Hydrologic Land Use Classification Using LANDSAT.

This report describes the Hydrologic Engineering Centers experience with land use classification from LANDSAT multispectral imagery. Land use is required for the estimation of hydrologic model parameters. The land use classification procedure used, developed at the University of California, Davis, for the Corps of Engineers, is an unsupervised, noninteractive approach requiring no special image processing equipment. Watershed land use was determined from LANDSAT digital data, entered into a geographic data bank, and compared with a conventional land use classification. Hydrologic simulation model parameters were estimated from land use and other basin characteristics. The generated discharge frequency curves, corresponding to the alternative land use classifications, permitted the hydrologic significance of accuracy in land use identification to be assessed.
