可靠降雨径流预报对降低洪水风险至关重要，本研究基于物理参数构建未校准的HEC-HMS模型，结合GIS技术对埃及萨法加河谷盆地进行水文模拟。结果显示百年一遇峰值流量达698.4 m3/s，其中子流域7最大达137.5 m3/s，总径流体积12288.5千m3。通过暴雨频率曲线（IDF）和SCS ...

为解决埃塞俄比亚巴罗阿科博河上游流域数据稀缺条件下的径流预测难题，研究人员创新性地将水文工程中心水文模型系统(HEC-HMS)与支持向量回归(SVR)相结合。研究显示：混合HEC-HMS-SVR模型性能最优，NSE达0.989、RMSE仅29.78 m3/s、R2为0.99，显著优于单一模型，为洪水 ...
