In this study, the effective (dominant) discharge for maximum sediment transport is calculated for 14 stations in the Godavari basin (for monsoon) situated on the major tributaries using the mean and rating (power law) curve methods. The return interval of the calculated effective discharge is studied. In addition, the discharges with 1.5- and 2.08-year return intervals are compared with the effective discharge resulting the fact that 2.08-year discharges are more related to effective discharge. Scaling law for sediment yield with the drainage area curve of the entire Godavari basin is developed with the best available data and compared with the scaling laws developed by Hugo (World Environmental and Water Resources Congress, 2011) for world rivers. In this paper, the estimated values of sediment yield with the drainage area are found to be 0.3 times lesser than the values obtained from the equation given by Hugo. In order to estimate the influence of the rainfall and vegetation density on the sediment yield of the basin, a similar model is adopted which was developed by Langbein et al. (39: 1076–1084, 1958); for basins in USA. As a result, it is concluded that the precipitation is responsible to the 17.5 inches of runoff, which mostly influence the sediment yield in the Godavari basin.

在这项研究中，使用均值和额定（幂定律）曲线方法计算了位于主要支流的戈达瓦里盆地（季风）中14个站点的最大泥沙输送有效（主要）流量。研究了计算出的有效放电的返回间隔。此外，将回报间隔为1.5年和2.08年的放电与有效放电进行了比较，得出的事实是2.08年的放电与有效放电更为相关。利用可获得的最佳数据制定了整个戈达瓦里盆地流域面积曲线的沉积物产量比例定律，并与雨果（世界环境与水资源大会，2011）针对世界河流制定的比例定律进行了比较。在本文中，流域的泥沙产量估算值为0。比从雨果给出的方程式获得的值小3倍。为了估算降雨和植被密度对流域沉积物产量的影响，采用了由Langbein等人开发的类似模型。（39：1076–1084，1958）；适用于美国的盆地。结果，得出的结论是降水是造成径流17.5英寸的原因，径流主要影响戈达瓦里盆地的沉积物产量。
