基于分布式水文模型的阿伦河流域输沙模拟
Simulation of sediment transport in the Alun River Basin based on a distributed hydrological model
摘要
Abstract
To reveal the characteristics of the sediment transport for the medium-scale basins in the cold region of the northeast China,a suspended and bedload sediment transport model,coupled with a self-developed phys-ically-based distributed hydrological model for calculating the rainfall and runoff coupling process,was con-structed in the Alun River Basin.The model was validated by comparing the sampling survey results of the particle size distribution and the calculation results in a control case,and was used to calculate the rainfall-runoff combined with sediment transport process in 2016.The results indicate that the root mean square error(RMSE)in model calibration is mostly smaller than 0.1.The sediment transport process in the study area is dominated by the runoff process and suspended sediment is the primary transport form,with over 90％of the total sediment transport during the flood period in 2016,and over 80％during the period of normal water level across the outlet of the study area.The monthly sediment discharge in winter accounts for less than 0.15％of the annual total value;while the contribution of the monthly sediment transport in June,July,September and October to the annual total value is larger than 15％in the rainy season.The results can provide the basis for the research on flow and sediment coupling processes in the cold region of the northeast China.关键词
