SRM融雪径流模型在奎屯河流域洪水预报的应用
Snowmelt runoff model applied in Kuitun River catchment for flood forecasting
摘要
Abstract
The medium and small rivers in China generally have low flood control standards and urgently need strengthened flood forecasting,especially in high-cold mountainous areas with insufficient stations and data,where it is difficult to distinguish the runoff produced by snowmelt from that by precipitation,which enhances the difficulty of flood forecasting.Snowmelt Runoff Model(SRM)is a hydrological model for simulating and forecasting the snowmelt runoff in mountainous watersheds.It plays an important role in the study of mountainous watersheds with snowmelt and precipitation as the main runoff sources.Based on SRM and taking Kuitun River as a typical case of medium and small rivers in high-cold mountainous areas of Xinjiang,we simu-lated the daily runoff of the catchment by extracting the snow cover rate through MODIS remote sensing data and collecting me-teorological data.The results showed that the snowmelt runoff model could well simulate the runoff process of Kuitun River catchment,and its Nash efficiency coefficients in both calibration and validation periods exceeded 0.7,which means that the snowmelt runoff model can be applied to flood forecasting in Kuitun River.The model has some guiding significance for the flood prevention and early warning in medium and small river catchments of high-cold mountainous areas.关键词
