Analysis of Hydrological Characteristics of River Basin Based on Arcgis: A Case Study of Qinhe River Basin
On the basis of understanding the basic principles of hydrological analysis based on DEM data, this paper introduces the method, steps, and process of using 10.8 for hydrogeological analysis. According to the rich topographic and geomorphic information in DEM, the hydrological analysis tool provided by 10.8 is used to simulate and analyze the hydrological characteristics of the Qinhe River basin without depression, extract the real flow direction, Cumulant of confluence, and river network information of the region, simulate the Qinhe River basin, quickly and accurately identify all sub basins, and determine the location of the basin outlet, so as to realize the simulation and analysis of the hydrological characteristics of the region. The research contents and results provide help for hazard prediction, soil quality research, precipitation analysis, and application analysis of Hydrological model.
