Study on Digital Simulating Flood-Waterlog and Evaluating Damage Based on GIS
基于GIS的流域洪涝数字模拟和灾情损失评估的研究

Geographic information System (GIS) and remote sensing make it practicable for nonstructural measures, multidisciplinary, which is one of the effective methods for reducing damage caused by flood and waterlog disaster. The authors make a systemtic exposition of application of GIS in digital simulating flood-waterlog harzard and evaluating the loss within river basin from disigning of basin database, numeral simulating flood harzard forecasting and flood routing in river course and floodplain, modeling victims dispersion, etc. It provides a basic framework for developing similar research in the future.
