使用确定性和统计方法对流入康巴特湾的索拉什特拉地区河流的设计洪水进行了规划、设计和管理。通过比较这些方法获得的结果,可以很容易地估计给定设计回归期的流量或峰值流量,并可以确定该方法对该研究区域的适用性。本研究以索拉斯特拉邦9个流域20座水坝为研究对象。虽然索拉什特拉邦是印度最缺水的地区之一,但它却受到洪水问题的困扰,因为雨天的数量非常少,降雨强度非常高。由于是一个受管制的流域,大坝研究是首选。采用中央水利委员会(CWC) 2001年报告中提供的综合单位线(SUH)和区域洪水公式(RFF)方法对3a分区进行了确定性分析。统计方法采用降雨频率分析,采用gumbelo ev1分布。由于这些水工设施没有溢出,而且上游的蓄水大坝严重影响了9个河流站点的年洪水数据。因此,这些数据违背了原生流的基本原理。因此,没有进一步尝试对这些数据进行分析。 The main objective of study was to carry out the rainfall frequency analysis for these river basins to get 24 hour rainfall for a return period of 25, 50 and 100 years for an individual basin instead of using the value obtained by iso-pluvial map to estimate the design flood. The overall results reveals that due to construction of number of dams in 9 river basins, design flood estimation on each dam by using deterministic approach is more feasible.Revised design floods using SUH and RFF method on the basis of estimated rainfall indicates over-estimated and under-estimated design floods. Since the percentage difference is very less between revised SUH and revised RFF method. So, for safety purpose one with higher value should be used.
