Abstract

Precipitation is the main component input of watershed in flood, water balance and water resources computation. Any rainfall-runoff simulation of basin response by models needs the accurate amount of rainfall over the basin. Therefore the simulation of SPATIAL DISTRIBUTION of rainfall is an important factor. Measuring rainfall in scattered point stations and generalizing it to arial extent often causes considerable errors. Such source of error is one the most important in both rainfall-runoff simulation and continues hydrologic process and water balance modeling. A number of methods of interpolation and extrapolation of rainfall data has been developed which have some limitations and need to be evaluated accurately for finding the most appropriate one based on specific local conditions. For the purpose of the research a wide range area in the south west of IRAN with about 258552 km2 was selected and different methods of interpolation were evaluated in regional homogeneity analysis. The results show that delineation of regional homogenity partly improves the SPATIAL DISTRIBUTION of rainfall. Another conclusion is that using estimated data for data compellation has not improved the overall results.
