Abstract

The RAVAND RIVER DRAINAGE basin area with 2297 km2 is located in the southwest of Kermanshah province. Sometimes due to heavy and short-term precipitation, there is a risk of FLOODing and river FLOODing in this region. Survey of precipitation statistic of two rain gauge and synoptic stations and one hydrometric station during the period 1368-1384 showed that parameters such as time of precipitation, precipitation type, heavy and short-term precipitation and 24 hours precipitation can cause FLOODing in the region. With regard to Mediterranean climate of this basin area with 70 percent of annual precipitations, it should be mentioned that heavy rainfall in this study area is consistent with the precipitation so that in any year exceed the amount of rainfall has also increased as a result of heavy rainfall. Also, in this area 64.66 percent of the annual precipitation is more than 1 mm, 30.67 percent of precipitation is more than 10 mm and 4.66 percent of precipitation is more than 30 mm. This study will try to know what relationship there is between the amount of precipitation and number of raining days and how it changes. Do these changes whether any effect on FLOODing or not? After preparing the data, maps and required information from related organizations, the necessary operations were performed on them by using the software, Minitab, Smada, Gis and Spss. Return periods, process and forecasts of precipitation and DEBIT were studied for ten years. The results show that study area is getting low rainfall but rainfall intensity is greater. Furthermore, the human and natural factors are affected FLOODing rising.
