Abstract

Inaccessibility of data regarding sediment distribution during rainstorms is an ever prevailing problem in soil and water conservation projects in IRAN. Sofar, the relationship between sediment discharge and water discharge has only been investigated through employing exponential equations, in which the positions of studied discharges have not been taken into account. In this paper, an attempt has been made to investigate the relationship between sediment and water discharge in rising as well as falling limbs of HYDROGRAPH using field measurements as well as by the help of regression concept. The endeavor was implemented in a part of CHAHARMAHAL AND BAKHTIARI Province, namely zarinderakht watershed in Western IRAN. The results revealed that the application of Regression Model is an easy and suitable technique for promoting the accuracy of sediment estimation through which the generation of total SEDIMENT GRAPH is achievable. Besides that, the transformed exponential equation bearing a regression coefficient of 90% was found to be a better interpreter for the relationship between water and sediment discharge than the one whose regression coefficient was 78%, only. The relative error of estimation of the developed models was also less than the acceptable level of 32.6%.
