The dynamic nature of urbanizing watersheds is documented by analysis of thirteen small watersheds in the Denver suburbs for the percent area of ten surface materials using aerial photographs at five to ten year intervals (concrete, asphalt, rooftop, gravel, lawn, natural, agricultural, forested, bare soil, and water). The results clearly show the changes in impervious areas in these watersheds as a function of year and time of year. A method is outlined whereby remote multispectral imagery can be used to map these surface characteristics which in turn can be related to surface hydrologic units and used as input into a watershed simulation model.
