The development and initial application of a computer model of the hydrology, water rights, and operation of the Provo and Weber rivers in Utah are described. The new FORTRAN model PROSIM (Provo River Simulation Model) makes use of all pertinent meteorological, hydrological, land use, and system facility data to describe and simulate the operation of the 700 square mile Provo basin and the upper 1,600 square miles of the Weber basin. Water rights information comes from a detailed review of the previous adjudications of the basins, and an investigation and interpretation of the existing and future institutional arrangements and procedures on the river systems. The model itself continuously calculates the availability of water throughout the river system, and allocates water in prioritized basin-rank order. The simulation capabilities in the model include (1) direct diversion water rights, (2) transbasin diversions, (3) irrigation demand estimation, (4) return flow calculation, (5) reservoir, ditch/canal, and stream channel operation and accounting, (6) equal allocation of water shortage, and (7) instream flow requirements. The PROSIM model development study was performed by Montgomery Watson, under contract to the Central Utah Water Conservancy District (CUWCD) with funding from the federal government.
