摘要
采用水力学模型,对溃坝流量以及溃坝后下游各断面的淹没水深和淹没范围等水力风险要素进行计算,基于ArcGIS技术开发了江苏省句容市北山水库洪水风险图管理系统,对GIS空间属性表字段进行渲染,自动绘制出溃坝洪水淹没风险信息,为下游句容市区防洪减灾提供技术支持。
The flood discharge and downstream flooded depth and scope are calculated by using hydraulic models after dam failure, and the results are used to establish the ArcGIS-based information management system for flood risk mapping of Beishan Reservoir in Jiangsu Province. The flood risk information is automatically mapped through dressing up the field of attribute table of spatial data. The flood risk information management system can provide technical support to the flood control and disaster mitigation of Jurong City in downstream.
