| Summary: | Land use and land cover are important factor influencing hydrologicalsimulation. In order to explore the influence of land use data with differentresolutions on SCS model for simulating rainfall and runoff and reducing the modelerror in rainfall and runoff simulation, taking the Yiluo River Basin as theresearch object, and combined with the land use data of 2005, 2010 and 2015, thispaper simulates the rainfall and runoff of these three years, and compares andanalyzes the influence of land use data sets based on different resolutions on theCN value of model parameters.The study shows that SCS model has a good simulationeffect on runoff generated by concentrated rainfall in the Yiluo river basin. Theresolution of land use data has a great influence on the CN value. The error ofmodel simulation can be reduced by applying land use data with higher resolution,with error reduction range between 5% and 10%. |
