Abstract

Using the given method by SCS to examine the effects of abstraction of RAINFALL on soil and how to form flood hydrograph for hydrulic structure is the main subject of this research. In this field, climatic factors as severe RAINFALL have been applied and related physical factors and soil vegetative cover have also important role to change RAINFALL into RUN OFF and have been analyzed in a specific geographical zone Bagh malek watershed basin. One of the major methods used to examine the way of forming RUN OFF because of RAINFALL on the earth, is a common method of (SCS). On the whole, this method considers the conditions of soil and its vegetative cover to change RAINFALL into RUN OFF. In this study, the results of estimation in the filed of changing RAINFALL into excess RAINFALL has been studied as curve number (CN) by using 2 different methods estimating CN has been documented with soil’s characteristics and surface vegetative cover and another method accompanied by observations and hydrulic conditions related to flood which is an estimation of CN method and has been analyzed. On one hand, the process of forming RUN OFF using SCS method and estimation of excess RAINFALL of hydrographs has been studied and compared. Existing difference in the process of estimation and observation of RUN OFF has also been examined. By using the phenomenon of “RAINFALL-flood” some observations have been performed for the calibration of HEC-HMS model, by which curve number (CN) has been estimated. The results of estimation of CN method by the mentioned model is compatible with those of observed CN.
