基于MIKE SHE分布式水文模型的降水时间尺度对喀斯特流域径流模拟的影响研究——以红水河系六硐河流域为例
Research on the impact on runoff by time-scale of the precipitation in karst basin in view of MIKE SHE model:A case in Liudong river of the Hongshuihe system
摘要
Abstract
Runoff is the outcome of hydrological response to precipitation by river basin system. The essence is that the precipitation is reallocated spatially and temporally within the basin. As one of the greatest uncertainties , spatial and temporal characteristics of precipitation are the main factor that affects the runoff modeling and the other hydrological problems. To research the impact on runoff by precipitation time-scale in karst basin, MIKE SHE is applied to five floods in a typical karst basin, and the correlative parameter of the MIKE SHE is selected and calibrated in combine with the unique landforms and hydrological characteristics in the karst basin in this paper. Moreover, in order to study the impact on flood modeling process by variation in precipitation time, the time-scale of precipitation data is changed in this research. The result shows that runoff will increase and flood peak will delay with the increase in temporal scale.关键词
