This course focuses on the application of hydrological model. Starting from the principle of optics, and understand the way for image correction and image classification through the image interpretation processes. Then, we will learn the way to classify the land use from satellite image. At the same time, the basic concepts of distributed hydrological models will be introduced. The GIS satellite image will be introduced to explain the way to deal with the necessary hydrological factors of the hydrological model. Once the necessary factors of hydrological model were built, students can test the model response with different rainfall conditions, and discuss its possible reasons base on the runoff process.
