Outline Activities
The research stands fundamentally on Hydrology and Environmental Hydraulics, and are related with the analysis, prediction and control of the water environment in closed waters and estuarine-coastal areas. Ongoing research topics are the hydraulic and hydrological functions in flat low-lying agricultural areas, the environmental hydraulics in closed waters, estuaries, irrigation and drainage canals, and the ecological function of hydraulic structures.
