Simulation of rainfall-runoff process using HEC-HMS model for Balijore Nala watershed, Odisha, India。
近些年，由于气候变化和人类活动的双重作用改变了流域下垫面的水文特性，探讨研究下垫面变化的水文响应过程具有重要的理论和现实意义．河南伊河洪水虽然量级不大，但发生几率较高，对水库运用和河道冲淤的影响较大．如果洪水变小，伊河下游的造床流量也相应减小，水库控制中常洪水的流量及所需的防洪库容可做相应调整，反之亦然．因此，为了科学治理和管理伊河，开展伊河中下游洪水变化研究也是非常必要的．通过HEC模型对伊河上...
