Abstract

Floodwater is alwage one if the Natural disasters. And put people at risk and created more Financiql and Spirit loss por human. Damming is on of the effective wag in reducing of Flood water damage and also for using of waters in bock of the dam for various consumpotation. The aim of this Studg is to determine of chenching hgdrologic Flow charaacteristics to the constrction of the dam using the continuitg curve in the rivers South Loke urmia. For this reason we ar Studied hgdrometric deta in Studied Station thaht their total number is 31 Station. And Damming is determined on each of Station using Google earth Software and Station under effect of dam are determined with mentioned software. From 31Station in South of urmia Lake, 10 Station were under effect of dam. After determining of Station under effect of dam, their Continuitg Current curve was drawn up. Anjin excel area Studied 19 index for under effected dam Station. That divided in to group: peak flow, Flow duration, Low flow, Flow variability and of final this indexs analgsed via Spss Software. Results showed that Station under effect of dam are along with current Change. Also according to drawn continuity current curre for this to Station and usage of 50% debi in this curve that divided current to minimum and Maximum part, debi mass before construting of dam and after constructiong of dam is more than is mass in debi with low amount. Mass after dam constructing. Keg words Flood water, hgdrologic index, continuitg current curre, damming.
