Nash model relation to horton order ratios

WitrynaNash used his model in 1962 for some British catchments. He has established experimental relations between watershed properties and n, k parameters and presented Nash’s synthetic model (Singh, 1988). THE SCS MODEL SCS method is one of the methods that can be used for computing UH in watersheds with insufficient data. http://yadda.icm.edu.pl/yadda/element/bwmeta1.element.agro-dada72c3-d646-4f49-b54d-84314bb2e14f
