摘要
针对缺资料地区水电工程水文计算难题,以国外两个水电站设计为例,在掌握全球共享气象、地形、植被、土壤基础数据的前提下,以基于3S技术的分布式水文模型SWAT为工具建模,利用Nash-Sutcliffe效率系数及相对误差指标评估径流模拟精度,论证分布式水文模型在缺资料地区水电站径流计算的可行性。
Aiming at the difficult problem of hydrological calculation of hydropower projects in data-deficient areas, the paper takes two hydroelectric power projects abroad as examples. On the premise of global sharing basic meteorological, topographic, vegetation and soil data, the distributed hydrological model SWAT(Soil & Water Assessment Tool) is used as a tool to modeling. The paper uses the Nash-Sutcliffe coefficient and relative error index to evaluate the runoff simulation accuracy, and demonstrates the feasibility of the distributed hydrological model for runoff calculation of hydropower stations in data-deficient areas.
