东北地区渍涝风险气象等级预报
Waterlogging Forecast in Northeast Area of China Base on DEM
摘要
Abstract
To meet the requirements of waterlogging in weather disaster forecast. Using 1:1 000 000 scale DEM basic topographic data in the Northeast area of China, based on the platform of geographic information system ( GIS) , the direction of water flow and the grid of convergence capacity were analyzed. SCS hydrology model was debuged, runoff model and converge ability were coupled, the runoff on Iiaoning terrain was obtained. According to the parallelism between converge and waterlog grade, the waterlog risk meteorological grades were obtained. In flood seasons the waterlogging forecast was applied, the result showed that the forecast and actual condition are consistent.关键词
