By conducting flume experiments, we obtained the time changes of flow profiles with water and two type of viscous liquids. We reproduced the time changes of experimental flow profiles by computing with both the numerical model with Bingham model and the numerical model with Manning model. The results said that the numerical model with Bingham model could reproduce the experimental flow profiles including both rarefaction waves and shock waves. And the numerical model with Bingham model could reproduce more accurately than the numerical model with Manning model.. |

Due to heavy rainfall, floods and sediment disasters such as collapses and debris flows occurred predominantly in the Kuma River basin of Kumamoto Prefecture. We conducted field investigations at four sites in Ashikita Town and Tsunagi Town, Kumamoto Prefecture, where collapses and debris flows caused deaths. We also conducted field investigations in the Kawauchi River branch of the Kuma River, where vast amounts of sediment discharge caused damage to houses. The objectives of these investigations were to clarify the situation and mechanism of the disasters and to propose procedures to recover from the disasters. This report briefly summarizes the results of these investigations.. |

In volcanic areas with tephra deposits, landslides expose tephra and not bedrock. Therefore, the immunity of landslides in volcanic areas may be different from that of landslides in non-volcanic areas. Herein, we developed landslide inventory maps (LIMs) for 6 periods during 1955–2016 using aerial photographs and digital elevation models in northern Aso Volcano. In this area, landslides were found to continuously occur due to rainfall events and a large earthquake. Using the 6 LIMs, we examined the terrain attributes (i.e., slope angle, slope aspect, and normalized distance to ridge) and the overlap of landslides. Among the terrain attributes, slope angle was a dominant factor affecting the occurrence of landslides caused by both rainfall events and an earthquake. The total landslide areal density in 2016 was 50% for a slope angle of 35%–45%. 2 atypical events (a rainfall in July 2012 and an earthquake in April 2016) caused landslides to occur on slopes that were relatively resistant to landslides by typical amounts of rainfall, resulting in high landslide density in 2016. The intensity of rainfall for an event in July 2012 was considerably higher than that for other rainfall events. The type of landslides caused by an earthquake in April 2016 was different from that of landslides caused by rainfall. The depths of some landslides caused by this earthquake were deeper than those of landslides caused by the rainfall in July 2012. The overlap ratio was |

This study aims to optimize causative factors using logistic regression (LR) and an artificial neural network (ANN) to produce a LSM. The LSM is produced with 11 causative factors and then optimized using forward-stepwise LR (FSLR), ANN, and their combination (FSLR-ANN) until eight causative factors were found for each method. The ANN method produced superior validation results compared with LR. The ROC values for the training data set ranges between 0.8 and 0.9. On the other hand, validation with the percentage of landslide fall into LSM class high and very high, ANN method was higher (92.59%) than LR (82.12%). FSLR-ANN with nine causative factors gave the best validation results with respect to area under curve (AUC) values, and validation with the percentage of landslide fall into LSM class high and very high. In conclusion, ANN was found to be better than LR when producing LSMs. The best Optimization was combination of FSLR -ANN with nine causative factors and AUC success rate 0.847, predictive rate 0.844 and validation with landslide fall into high and very high class with 91.30%. It is an encouraging preliminary model towards a systematic introduction of FSLR-ANN model for optimization causative factors in landslide susceptibility assessment in the mountainous area of Ujung Loe Watershed.. |

For example, the highest daily rainfall was 803 mm on July 5, 2017 at Kurokawa, Asakura-City of Fukuoka Prefecture. The heavy rainfall caused many slope failures, debris-flows, sediment-flows and floods, which killed 37 people at the current stage. Phenomena such as surface slope failures and sediment-flows were concentrated around the eastern part of Asakura-City. They flowed down as floods and damaged many residential areas. The bedrock where the phenomena occurred was not only weathered granite but also weathered schist included in Sangun metamorphic rocks. It is a very important feature that enormous driftwood has discharged by sediment-flows, floods and so on. Some large failures also occurred out of Asakura-City. In Hita-City of Oita Prefecture, a large failure with a width of ca.200 m, a length of ca.350 m and a depth of ca.15 m occurred and blockaded Ono-river. Because this disaster caused serious damage to surrounding areas, the comprehensive countermeasures such as construction of sabo-facilities and setting warning-evacuation system must be needed.. |

Water and sediment go down streams that have conjunctions, curves, narrow and wide parts, so that the numerical simulation has to treat the complex geometry. Moreover, it is necessary for the numerical simulation to be applied for not only very fast flows such as debris flows and floods but also very slow flows such as still water. The numerical simulation needs to be based on unstructured mesh and to be improved in order to handle very slow flow such as still water. This study aims to develop a numerical model for still water and to verify the numerical model by reproducing the experimental results. In the developed numerical model, it is assumed that the averaged gradient of flow surface is equal to the resultant force of the hydrostatic force acting on the boundaries of element. It is found that the numerical simulation with the developed numerical model can reproduce the still water and the surges triggered by the flow going into the reservoir.. |

However, this method has some problems, for example, when the sediment rate is high, the sound level is continuously high, and thus, the number of pulses decreases or becomes zero. This problem can be eliminated by recording and integrating the sound pressure. Results of flume experiments carried out using glass beads have confirmed the existence of a relationship between the sediment rate and sound pressure. When the number of beads is small, the sound pressure is proportional to the sediment rate. As the number of beads increases, the detection rate, which is the ratio of the experimental value of the sound pressure to the anticipated value calculated with the proportional relation, decreases due to the influence of the interference of sound waves. These results agree well with those of a numerical simulation carried out using the wave data of the individual collisions. These results suggest that the transformed data whose sediment rate is equal to the integral multiple of that of the original data can be calculated by dividing and superposing the original data. In this study, we propose a method involving the use of the ratio between the detection rate corresponding to the transformed data and original data to calculate the detection rate and number of beads. We thus compute the sediment rate and average grain diameter.. |

Also, Typhoon Namtheun brought heavy rainfalls to the Kinki and Shikoku regions between July 30 and August 1, 2004. Total rainfall in the upper reaches of the Nakagawa River exceeded 1, 000mm. These rainfalls triggered a number of sediment related disasters. The NILIM and PWRI investigated these sediment related disasters shortly after they occurred. Here we report on (1) characteristics of sediment related disasters in Fukui and Tokushima, (2) spatial distributions of sediment related disasters and their relation to rainfall amount variability in Niigata and Fukui, and (3) effectiveness of sabo dams against debris flows.. |

The mixture of sediment and water was set so the simulated muddy debris flow would maintain Froude similarity with the May 1998 debris flow near Sarno, Italy. The flume was 20 cm wide, 40 cm deep, and 500 cm long, and it was set at two different slopes of 5° and 10° . The wooden dam models included three slit types with widths of 5 cm, 10 cm, and 15 cm and three square conduit types with sides of 5 cm, 10 cm, and 15 cm. After the sediment and water were mixed for 6 minutes with two electric drills equipped with a special propeller in the upstream space from a gate, the gate was opened manually to create a muddy debris flow in the flume. Sampling boxes on a roller at the bottom end continuously collected the muddy debris flowing from the dam models. Both the slit and conduit dams lowered the peak flow volume. The smaller the dam dimensions, the lower the peak discharge rate. Surges were observed forming upstream from the dam models. Equation of continuity, momentum equation, and energy equation for positive surge obtained equations representing the surge formation conditions and discharge rate. Their application to the experimental results showed that the calculated values generally reproduced the test results.. |
