Method and apparatus for determining runoff using remote geographic sensing

摘要: Images of a selected geographic region are obtained using remote sensing apparatus and processed to determine characteristic spectral reflectance patterns associated with different ground covers soil types in the region. The image processing means compares pixel values order classify each cover or type class, corresponding pattern for which matches value. In preferred embodiment invention, Geographic Information System (GIS) software is utilized combine remotely sensed providing classifications same generate rainfall loss function. function can then be used runoff curve number (RCN) region, probable maximum flood (PMF), various design hydrographs precipitation events computer water shed model.
