Abstract:
turkey has very different geomorphologic hydrologic and climatic conditions so the runoff coefficient should be different from one basim to another but only a constant value 0.37 is being used for all the basins in turkey in this study monthly seasonal and annual runoff coefficients of 48 sub -basins in western and southern part of anatolia are determined by using synchronous rainfall -runoff data of 26 years record period and their temporal and spatial distributions are investigated . the relationship between the basin parameters and the runoff coefficient is also examined.
