In areas with heavy precipitation and rugged topography, these parameters control the occurrence of some natural hazards, from which the flash flood gets the most attention. Traditional methods for the assessment of the surface hydrological parameters are costly, time-consuming and provide information for limited geographic extent. On the other hand, remotely sensed data provide a cost-effective, rapid and wide aerial coverage with adequate accuracy. Geospatial analysis of these remotely sensed data provides a suitable and effective method for the reconnaissance determination of the surface hydrological parameters. In this work, digital elevation models, Landsat 8 satellite images as well as digital maps of soil and land use for Kyushu Island were acquired and analyzed using geographic information system. Surface hydrological parameters were determined in terms of watershed boundaries, soil moisture, initial abstraction as well as flash flood potentiality. Results of this research show a great correlation with historical flash flood events that occurred in the island. The northern parts of the island are subjected to the threat of flash floods. A follow-up is recommended in some areas on the island. As a conclusion, the geospatial analysis performs an accurate reconnaissance method for hydrological analysis at regional scale, which in turn guides the detailed field observation saving time and cost..

3-D gravity modeling using hexahedral element in Kinigi geothermal field, Rwanda, Arabian Journal of Geosciences, 10.1007/s12517-019-4249-8, 12, 3, 2019.02, [URL], It is important for geothermal exploration to know regional subsurface structures. The gravity survey is often used to narrow down the promising area at the early stage of geothermal exploration. The gravity survey was carried out to estimate subsurface density structure in the Kinigi geothermal field, Rwanda, in September 2015. In order to interpret the gravity anomaly distribution, 3-D gravity modeling was done by using the new program based on Gauss-Legendre integration using hexahedral elements. As the result, the computed gravity anomalies showed high gravity anomalies in northwest, the northeast, and east-southeast of the studied field and low anomalies in the southwest side of the studied field as Bouguer anomalies. The area was characterized by normal contacts with main boundary trending NW-SE direction. This boundary was estimated as main fault in Kinigi geothermal field, Rwanda. The detected fault could be a better place for installing geothermal wells for future geothermal development in the region..

The studied area is characterized by an intensive imbrication zone of serpentinites and metavolcanic rocks. The integrated use of aeromagnetic and spectral reflectance remote sensing data has proved effective for mapping geology related to ore deposits. Spectral reflectance maps have been produced to discriminate various rocks, such as serpentinites, gabbros, and metavolcanic rocks. 3-D inversion of aeromagnetic data acquired over the Um Salatit study area produced a 3-D magnetic susceptibility model showing magnetic bodies surrounded by less magnetic host rock. The magnetic features are elongated ENE-WSW parallel to the major thrust fault and mapped the Um Salatit serpentinized rocks. Remote sensing data allow investigating surficial geological features and mapping the mineralized areas. Remote results, in conjunction with 3-D inversion of aeromagnetic data, demonstrate that gold occurrence in the study area was effectively restricted to the highly magnetic zone interpreted as host rocks..

Jean d.Amour Uwiduhaye, Hideki Mizunaga, Hakim Saibi, Geophysical investigation using gravity data in Kinigi geothermal field, northwest Rwanda, Journal of African Earth Sciences, 10.1016/j.jafrearsci.2017.12.016, 139, 184-192, 2018.03, [URL], A land gravity survey was carried out in the Kinigi geothermal field, Northwest Rwanda using 184 gravity stations during August and September, 2015. The aim of the gravity survey was to understand the subsurface structure and its relation to the observed surface manifestations in the study area. The complete Bouguer Gravity anomaly was produced with a reduction density of 2.4 g/cm3. Bouguer anomalies ranging from −52 to −35 mGals were observed in the study area with relatively high anomalies in the east and northwest zones while low anomalies are observed in the southwest side of the studied area. A decrease of 17 mGals is observed in the southwestern part of the study area and caused by the low-density of the Tertiary rocks. Horizontal gradient, tilt angle and analytical signal methods were applied to the observed gravity data and showed that Mubona, Mpenge and Cyabararika surface springs are structurally controlled while Rubindi spring is not. The integrated results of gravity gradient interpretation methods delineated a dominant geological structure trending in the NW-SE, which is in agreement with the regional geological trend. The results of this gravity study will help aid future geothermal exploration and development in the Kinigi geothermal field..
16. Biruk Abera Cherkose, Hideki Mizunaga, Resistivity imaging of Aluto-Langano geothermal field using 3-D magnetotelluric inversion, Journal of African Earth Sciences, 10.1016/j.jafrearsci.2017.12.017, 139, 307-318, 2018.03, [URL], Magnetotelluric (MT) method is a widely used geophysical method in geothermal exploration. It is used to image subsurface resistivity structures from shallow depths up to several kilometers of depth. Resistivity imaging using MT method in high-enthalpy geothermal systems is an effective tool to identify conductive clay layers that cover the geothermal systems and to detect a potential reservoir. A resistivity model is vital for deciding the location of pilot and production sites at the early stages of a geothermal project. In this study, a 3-D resistivity model of Aluto-Langano geothermal field was constructed to map structures related to a geothermal resource. The inversion program, ModEM was used to recover the 3-D resistivity model of the study area. The 3-D inversion result revealed the three main resistivity structures: a high-resistivity surface layer related to unaltered volcanic rocks at shallow depth, underlain by a conductive zone associated with the presence of conductive clay minerals, predominantly smectite. Beneath the conductive layer, the resistivity increases gradually to higher values related to the formation of high-temperature alteration minerals such as chlorite and epidote. The resistivity model recovered from 3-D inversion in Aluto-Langano corresponds very well to the conceptual model for high-enthalpy volcanic geothermal systems. The conductive clay cap is overlying the resistive propylitic upflow zone as confirmed by the geothermal wells in the area..

18. Mohammad Shehata, Hideki Mizunaga, Flash Flood Risk Assessment for Kyushu Island, Japan, Environmental Earth Sciences, 10.1007/s12665-018-7250-8, 77, 3, 2018.02, [URL], Using advanced geospatial analysis technologies, flash flood risk is assessed for the island of Kyushu, Japan. In this study, the flash flood risk is redefined in terms of the flash flood potential index (FFPI) and the flash flood residential hazard (FFRH). The island experiences rainy weather, especially in the summer (June–August), when catastrophic flash flood events have historically occurred. Studies of the surface hydrological properties of the island are very rare and localized; hence, geospatial techniques are most appropriate for the assessment process. The Soil Conservation Service rainfall-runoff model was used to estimate hydrological responses on the island. Four factors were included in the flash flood assessment. A multi-criteria analysis was carried out to map the FFPI and FFRH from the evaluation factors. The results show that the highest flash flood risk occurs in the northern parts of the island, where the soil displays relatively low infiltration rates and relatively high curve numbers, despite the comparatively low precipitation rates that occur there. The results indicate that soil hydrological properties are the main driving forces of flash floods, especially in regions with low precipitation rates. The results of this research are consistent with previous in situ measurements of runoff made at several sites on the island. The results also show a strong geographic correlation with historical flash flood events on the island. This research validates the use of geospatial analysis for large geographic regions where in situ measurements cannot be taken due to time or cost constraints. The results of this study provide decision makers with the information needed to select a management strategy to address possible future flash flood events that considers safety and water harvesting..

Society of Exploration Geophysicists - SEG International Exposition and 76tth Annual Meeting 2006, SEG 2006
, 1318-1322, 2018.01, This paper deals with the application of neural network technique for the three-dimension interpretation of mise-à-la-masse data from the Takigami geothermal field in Kyushu, which is one of the most active geothermal area in Japan. To understand the structure of the geothermal field, a 4-layers neural network had been developed. The training algorithm for the network is back-propagation with five paradigms, e.g. on-line back-propagation, batch back-propagation, delta-bar-delta, resilient propagation (RPROP) and quick propagation, were applied to find out the most efficient one. The network was trained with 3-D mise-à-la-masse simulation data set, including 864 cases of a single anomalous resistivity block of 10 Ohm.m moving in the model mesh with background resistivity of 100 Ohm.m. To generate the training data set, a high accuracy algorithm for 3-D numerical simulation, based on finite difference method and the algorithm of the singularity removal, was used. The trained network was tested by a synthetic data and then applied for the real field data set of the study area. The obtained results are remarkably correlated with the other available data from the field such as previous geoelectrical data, formation temperatures, lost circulation zones, hence, promising zones for production or re-injection can be indicated quickly at site of Takigami geothermal field..

Subsurface total count gamma-ray (GR) data were recorded in nine wells, seven of which possessed spectrometric data (eU, eTh, and K). The data show that RHP estimated from GR logs (ABR) varies from 0.13 to 1.73μW/m3, with an average of 0.7μW/m3 and a standard deviation of 0.26μW/m3. In addition, 72.9% of RHP values fall within the range of 0.6-1.0μW/m3. RHP estimated from the concentrations of radioactive elements (AR) vary from 0.13 to 2.1μW/m3, with an average 0.71μW/m3 and a standard deviation of 0.38μW/m3. 50% of these RHP values fall within the range of 0.6-1.0μW/m3. Cross-correlation of ABR and AR calculations yielded a moderate fit of 0.75. The three-dimensional (3D)-slicing of the reservoir shows that the northern and north-western parts of the study area have higher RHP compared to other parts. The estimated RHP can produce enough heat which has an effect on the hydrocarbon potential in Rudeis Formation..

, 2016-January, 590-594, 2016.01, In this paper, the authors propose a novel exploration system for ocean floor resources using an autonomous underwater glider and OBEM (Ocean bottom electromagnetometer). Studies on the gliding performance and the hydrodynamic characteristics of several kinds of body shape were carried out for the preliminary design of the system. Gliding ratios in a steady flow were estimated based on CFD calculation for different main wing shapes. The effects of the size of the body and the camber of the main wing were examined as well. It was confirmed that designed vehicle had efficient gliding performance to achieve the autonomous OBEM measurement..

The algorithm is distinctive for the level of accuracy it attains while bypassing the sensitivity matrix update. A common sensitivity matrix for homogeneous half-space is used in all iterations. Instead of updating the sensitivity matrix, the smoothness filter coefficients at each model element are updated, based on the spatial variations in resistivity in the model derived from the latest iteration. This substitution is expected not only to reduce the computation time required for large-scale inversions, such as those for 3D surveys, but also to allow the resolution of sharp boundaries in resistivity structures. Our algorithm was applied to 3D magnetotelluric inversion in order to confirm its effectiveness. Using synthetic examples under several conditions, we demonstrated that the method can reduce the number of forward calculations required to reduce data misfits to noise level, and that the method is robust for constructing target models even with sharp boundaries without generating fatally false resistivity structures or boundaries under noisy conditions..

, 2, 1494-1504, 2006.12, An advanced geoelectrical technique for imaging potential fractures has been developed by Engineering Geophysics Laboratory in Kyushu University. The method, Fluid Flow Tomography (FFT), has been applied to monitor fluid flow behaviors in a reservoir during water injection and steam production operations in geothermal areas. Distribution and extension of major fractures can be evaluated by 3-D inversion of induced self potential (SP) anomalies with a function of time and resistivity structures can be determined by 3-D inversion of the charged potential data in a surveyed area. It is concluded that fluid flow behaviors in a reservoir could be continuously traced and visualized as a function of time by the FFT method..

, 1615-1623, 2006.12, Mine clearing is an urgent matter to be tackled internationally not only from the humanitarian point of view but also from the viewpoint of reconstruction and economic growth in the area where a cessation of armed conflicts was achieved. Operations are already underway to clear landmines, but currently they rely heavily on human works due to a lack of safer and efficient demining techniques. Various geophysical exploration techniques have been applied to the problem of detecting and mapping underground mines and UXO with practical success. The most productive techniques are magnetic, electromagnetic and Ground Penetrating Radar methods for which the mine target exhibits the greatest physical contrast with the host geological formation. Developments of more sensitive geophysical equipments for detecting mines is required to meet the geophysical conditions of lower contrast with the environment and at the scale of the target. Starting from May 2004, a channel of communication between the Egyptian embassy in Tokyo and the Kyushu University Mine Action Group (QMAG) team on the topics of landmines in Egypt has been established on how to apply geophysical techniques newly developed geophysical techniques in Japan to solve the problem of landmines in Egypt. We arranged a campaign for landmines detection technology in Egypt, conducted by research teams of QMAG of Kyushu University. During the campaign three geophysical techniques, DC resistivity, magnetic and ground penetration radar were tested and evaluated..

, 2, 1374-1377, 2006.12, Several geophysical exploration methods have been applied to the problem of detecting and mapping underground archaeological remains with practical success. The most productive techniques are those for which the archaeological target exhibits the great physical contrast with the surrounding formation. Most widely used in archaeological prospection include Magnetic, Electromagnetic, Ground Penetrating Radar and Electrical Resistivity methods applied at the shallow surface. However, these conventional geophysical measurements for an archaeological prospection has been tried with relatively limited success. Therefore, we have developed an automatic imaging system named as Handy-ARM (Archaeological Resistivity Meter) for an archaeologist based on electrical resistivity techniques..

Supriyanto Suparno, Hideki Mizunaga, Keisuke Ushijima, 3-D MAM inversion in Sibayak geothermal field, Indonesia, Memoirs of the Faculty of Engineering, Kyushu University, 66, 2, 99-113, 2006.08, Sibayak geothermal field is located about 65 km to the southwest of Medan in the North Sumatra Province, Indonesia. Starting from 1998, a small-scale geothermal power plant (2 MWe) has been installed in this area. Since electricity demand increases in the North Sumatra Province, Pertamina Geothermal Energy plans to increase the capacity to 20 MWe. Accordingly, detailed knowledge of the reservoir structure and its extension must be determined for a new production target. The mise-a-la-masse (MAM) surveys were carried out in this field using the exploration well SBY-1 and the production well SBY-4 to delineate a new production target for further field development. A conventional one-dimensional MAM data processing has been done to obtain lateral variation of subsurface resistivity. However, the result is not satisfied to image real condition of the geology on the subsurface. Therefore, we carried out an advanced 3-D MAM inversion based on the smoothness-constrained least-squares method using a homogeneous earth as the simplest assumption of the starting model. Interpretation of the 3-D MAM model was done by combining the results with previous geo-electrical data and borehole information to image a promising reservoir zone. The resistivity model obtained from this study is characterized by a very low resistivity cap rock beneath a resistive layer and rather high resistivity layer of the reservoir. The very low resistivity layer is due to clay minerals such as montmorillonite. This interpretation result of the 3-D MAM model indicates that reservoir zones trend to the north-northeast direction of the study area, between Mt. Sibayak and Mt. Pratektekan, and shows a good correlation with the formation temperature and the lost circulation zone. This geophysical information is useful for the task of selecting sites for the promising zone in the Sibayak geothermal field..

Ho Trong Long, Hideki Mizunaga, Keisuke Ushijima, Borehole-to-surface electrical data interpretation at Takigami geothermal field in Kyushu, Japan using neural network, SEG Technical Program Expanded Abstracts, 10.1190/1.2369763, 25, 1, 1318-1322, 2006.01, [URL], This paper deals with the application of neural network technique for the three-dimension interpretation of mise-à-la-masse data from the Takigami geothermal field in Kyushu, which is one of the most active geothermal area in Japan. To understand the structure of the geothermal field, a 4-layers neural network had been developed. The training algorithm for the network is back-propagation with five paradigms, e.g. on-line back-propagation, batch back-propagation, delta-bar-delta, resilient propagation (RPROP) and quick propagation, were applied to find out the most efficient one. The network was trained with 3-D mise-à-la-masse simulation data set, including 864 cases of a single anomalous resistivity block of 10 Ohm.m moving in the model mesh with background resistivity of 100 Ohm.m. To generate the training data set, a high accuracy algorithm for 3-D numerical simulation, based on finite difference method and the algorithm of the singularity removal, was used. The trained network was tested by a synthetic data and then applied for the real field data set of the study area. The obtained results are remarkably correlated with the other available data from the field such as previous geoelectrical data, formation temperatures, lost circulation zones, hence, promising zones for production or re-injection can be indicated quickly at site of Takigami geothermal field..

The MT measurements have been conducted with irregular grid stations covering the Takigami area. The two-dimensional (2-D) inversion results of the MT data show that the resistivity structures in Takigami area are composed mainly of three layers, that is, high resistivity in the first layer overlying low resistivity in the second layer and resistive electrical basement in the third layer. The results are also in a good agreement with electrical resistivity logs, temperature distribution and lost circulation zone during the course of drilling. It is revealed from the interpretation of MT data that the geothermal reservoir of Takigami field is located at two different depths separated by Noine fault zone, which divides the subsurface of the area into eastern and western parts according to the characteristics of resistivity, permeability, temperature and depth of reservoir. The reservoir in the east of Noine fault zone is shallower than that in the west..

Ushijima, Comparative study of resistivity inversion at hamam faraun area, Egypt, Memoirs of the Graduate School of Engineering, Kyushu University, 60, 3, 117-128, 2000.12, DC resistivity method is commonly used for acquiring subsurface resistivity data in environmental and engineering investigations. However, its interpretation is hampered by a variety of factors of which the non-linear nature of the process and bias effects on the data; mainly due to the noise; are the most problem, which limit the model resolution to a large extent. The ability to invert resistivity data successfully depends on many factors such as the uniqueness of the model as well as the robustness of the inversion algorithm. Hereafter we are investigating this problem using three different 1-Diversion algorithms. The three algorithms have been applied to a numerical model of 4 layers to determine the optimum solution produced by each of them. A random noise of 5, 10 and 20 percents has been added to the model in a forward step to determine the most stable, robustness algorithm. Those algorithms have been applied to the field data set measured at Hamam Faraum hot spring area, Egypt, aiming to make a refinement to the previous 1-D inversion done before for the same data set (E1-Qady et. al, 1998). We could conclude that the algorithm of Meju, (1992), is the most effective one in this study. The resulted 1-D geoelectrical cross section could elucidate the subsurface structure and explain the origin of the hot water in the area..

The Fluid Flow Tomography survey method utilizes a casing pipe itself as a charged current electrode similar to the mise-a-la-masse method. The method has been applied to monitor fluid-flow behaviors during massive hydraulic fracturing operations and fluid-circulation experiments from injection to production boreholes. In the automatic recording system controlled by a personal computer charged potentials (mV/A) and spontaneous potentials (mV) can be simultaneously measured as a function of time at multiple stations (120ch) surrounding an operating borehole. Fluid-flow behavior in the subsurface could be visualized as a function of time by using contour maps of residual potentials from SP data and relative changes of apparent resistivity due to dynamic reservoir stimulations..
