Application of ArcGIS in the Calculation of Basins Rainfall-Runoff.

Abstract: It is key issue to predict the rainfall-runoff process on the Kuronagi River before the joint sediment flushing and sluicing of Dashidaira and Unazuki dams at the downstream of the Kurobe River. In this paper, the ArcGIS system is used to produce the digital basin of the Kuronagi River, the distributed Kinematic Wave hydrological model is used to calculate the rainfall-runoff process on the Kuronagi River, and the results are in good agreement with the observations. The results show that with the progress of rainfall observation techniques and computational methods, the development of digital land information and the effective application of GIS technology, a relatively simple rainfall-runoff model can get higher precision results.
