A unique integrated modelling system has been developed and applied for environmental assessment studies in connection with the Gabcikovo hydropower scheme along the Danube. The modelling system integrates model codes for describing the reservoir (2D flow, eutrophication, sediment transport),...

By some estimates, there are 47,000 large dams in the world. India had 4,635 “large dams” as per ICOLD definition. Only technical criteria such as height and storage volume are used for this classification. Large dam projects increasingly face opposition from the environmental lobby from...

Geographic Information Systems (GIS) have been recognised as a powerful means to integrate and analyse data from … modelling capabilities in GIS. This is still a rather complex task and research is being done on the full integration of these … models. Interfacing between these models and GIS may be a very efficient way of overcoming the difficulties and getting very …

The non-stationarity in runoff regime may be attributed to various causes such as climate change, land use change, and man-made runoff control structures. Degradation of land use can induce significant impact on infiltration and surface roughness leading to higher flood discharges. This study...
