Studying the Relationship between the Runoff, Precipitation, and Basin Flow Index in Wave Basin of Marg River in Mahidasht using S.C.S Method
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 1
Abstract
This study is aimed at evaluating loss methods affecting the runoff volume and hydrograph shape produced resulting from effective hydrological methods. Here, the effective parameters in the volume of runoff and were studied in Marg wave basin and Debi and precipitation values of the basin were prepared and arranged with common basis and their units were converted into millimeters. Correlation coefficient of the runoff was calculated with precipitation height and average annual precipitation was determined using calculus mean, Tisen and precipitation curves, and the annual aquatic volume of the basin was calculated based on each of the methods. To exactly recognize flood characteristics of the basin under study (beginning, continuance, end, and amount), hydrograph of Mahidasht Marg River was prepared. Then the hydrograph characteristics calculated including runoff volume and peak time was observed in corresponding hydrographs with the same properties. And the unit hydrograph was gained using Soil Conservation Service (S.C.S) method.
