【Abstract】 This paper makes use of a method of modelling still water level with contours generated from DEM, simulating flooding by reservoir and quake lake resulted from earthquake. By overlaying two dimension and three dimension geographic information on the model, GIS synthetical analysis is carried out for flood loss analysis and evaluation, flooded area prediction and emergency schedule.更多还原
