摘要

通过水文模型可以更好地了解世界各地的河流流域。然而，水文模型的开发和应用，特别是在气候变化的影响下，是一项艰巨的任务。本研究描述了使用HEC-HMS水文模型模拟Bhagirathi河流域的流量。该次盆地是恒河盆地的一部分，位于印度北阿坎德邦喜马拉雅山脉。Tehri大坝水库是一个季节性调节水库，流域水文状况的变化需要改变其运营策略。HEC-HMS模型模拟了2010年至2015年的单年和三年时间窗口，包括模型的校准和验证。模拟结果表明，观测数据与模拟数据非常吻合。HEC-HMS模型在模拟Tehri出口流量方面的效率已在本研究中得到明确证明。

Hydrological modelling of Bhagirathi River basin using HEC-HMS

River basins around the world are better understood through hydrological models. However, the development and application of hydrological models, particularly under the influence of climate change, is a daunting task. The present research describes the simulation of streamflows in the Bhagirathi River basin using HEC-HMS hydrological model. This subbasin is a part of the Ganga basin and is situated in the Himalayan state of Uttarakhand, India. The Tehri dam reservoir is a seasonally regulated reservoir, and changes in the hydrological regime of the river basin would necessitate changes in its operational strategies. The HEC-HMS model is simulated for single and three-year time windows from 2010 to 2015, including calibration and validation of the model. Results of the simulation indicated a close agreement between the observed and simulated data. The efficiency of the HEC-HMS model in simulating the streamflows at the outlet of Tehri has clearly been demonstrated in this research.
