Abstract

Prediction equations for RUNOFF depth from rainfall in small mountainous catchments located in the north and south face of the Alborz chain have been derived in this research. For this purpose two catchments were selected so as having full and reliable rainfall RUNOFF data and suitable regionally representative distribution over the studying area. The prediction equations have been obtained based on the RAINFALL DEPTH, ANTECEDENT PRECIPITATION INDEX and base flow. Statistical methods were used to obtain the multiple linear regression equations, correlation coefficients and the standard error for each of the techniques used for the watersheds. All peak events greater than 0.7 cms for Amameh representative catchment and also all peak events greater than 1.0 cms for Kasilian representative catchment were considered for analysis and deriving final equations. The standard error of the optimum prediction equations for RUNOFF was 0.248 and 0.205 mm for Amameh and Kasilian representative catchments, respectively. Also, the multiple correlation coefficient (R) was 0.842 and 0.857, respectively. Finally, the results of the developed regression equations were extended to the neighboring catchments of similar hydrological characteristics.
