The Uncertainty in Spatial Rainfall Distribution––A Case Study for Binh Dinh Province, Vietnam
The rainfall is considered as the key factor, greatly affecting the hydrological regime of the basin. This has been confirmed through many previous studies. Therefore, the distribution of rainfall by space has a certain impact on the study results and analyses of the flow regime of the basin, especially for large basins. The quality of rainfall data which is distributed by space depends on many factors, within a basin, the density of the rain gauge station is considered as the most important factor and has the greatest influence on the formation of the flow. The more the density of the rain gauge station, the more detailed the rainfall process takes in the basin, from that give for more accurate results in researching on the hydrological regime of the basin. For the purpose of improving the quality of distribution of rainfall by space, building a spatial rain database for the study of hydrological regime of basins in the province. This research conducts comparison about advantages and disadvantages of different rainfall distribution method. The study is realised with 21 rain gauge station over 6071 km2 of Binh Dinh province. The study is expected to provide useful basics for the catchment hydrological modelling, as well as demonstrating the uncertainty of different spatial interpolated methods in rainfall distribution.
