The MOSES code Version 1.0 is an interactive, menu-driven code for microcomputers. The code estimates the probability that spills of mineral oil or other fluids from substations or above ground storage tanks will or will not reach nearby surface waters. A range of spills can be simulated (i.e., from small leaks to failure of an entire above ground storage unit or the maximum volume of one unit). The code can also be used to help design substations by predicting the effect of changes in substation features (e.g., increasing the size of the on-site gravel bed or adding additional on-site sumps). Output of the model includes the probability that a spill will remain on-site or reach surface water and graphs showing selected characteristics of spills which reached surface water (e.g., spill size, volume reaching surface water, and distance to river). The distribution of the spill sizes contained on-site can also be plotted. The processes considered in the simulation include on-site and off-site storage, infiltration, evaporation, off-site retention, transport by overland flow, and the effect of rainfall (i.e., decrease in available storage and increase in transport by surface water runoff). The code uses a Monte Carlo approach for selecting input parameter values from user-defined ranges. The values used in the simulations for the cases where mineral oil reaches surface water can be saved as output files for later review. The code operates on IBM-compatible microcomputers equipped with a color monitor and an EGA or VGA video card, at least 640K memory, and a math coprocessor. The code is distributed in an already compiled/linked form and is available on one 5-1/4 in. high density diskette, on three 5-1/4 in. double density diskettes, or on one 3-1/2 in. high density diskette. This manual includes instructions for installing and using the code, example applications, methods for estimating the input data, and the theoretical basis for the code. 4 refs., 19 figs., 3 tabs.
