An erosion-deposition model, originally developed for a mainframe computer, was adapted for an Apple IIe. With minimal adjustment it can also be used on other personal microcomputers. The model is user oriented and utilizes readily available data. It predicts distribution of erosion and deposition on a watershed and provides information for selecting optimal management practices. Its application is illustrated using rainfall, topography, and soil data from a mined and reclaimed watershed in Pennsylvania. The model satisfactorily predicted sediment load at the outlet of the watershed and at the holding ponds. The simulation package can be used to plan location of detention basins, in channel design studies, and in land use planning.
