TY -的T1 -估计设计洪水的河流Saurashtra地区贡献到墨西哥湾的Khambhat Y1 - 2016-10-29 N2 -设计洪水已经估计了河流Saurashtra地区贡献到墨西哥湾的Khambhat使用确定性以及统计方法进行规划、设计和管理的水工建筑物。通过比较这些方法得到的结果,可以很容易地估计给定设计返回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。在本研究中,我们分析了sauurashtra地区的9个流域和20个大坝。虽然索罗拉斯特拉是印度最缺水的地区之一,但它却遭受着洪水问题的困扰,因为下雨的天数非常少,降雨强度非常高。由于是一个调整盆地,大坝明智的研究是首选。采用中央水利委员会(CWC) 2001年报告中提供的3a分区的合成单位水文曲线(SUH)和区域洪水公式(RFF)方法进行了确定性方法。统计方法采用降雨量频率分析,采用gumbel的ev1分布。由于这些水工建筑物并没有溢出,而上游的蓄水坝又严重影响了九大河址的年度洪水数据。因此,这些数据违反了原始流的基本原理。因此,没有对这些数据进行进一步的分析。 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.
