Abstract

A water budget model was applied to the San Juan basin aquifer New Mexico and Colorado. Direct recharge was estimated at the mouth of 272 surface basins. Mean annual winter precipitation for each surface basin was weighted upon the respective basin area and the isoline intersecting each basin using a Geographical Information System (GIS). Overall winter precipitation component was estimated at 8,600 cubic feet per second for the aquifer basin.Mean annual discharge for three distinct physiographic regions were used to estimate the streamflow component. The overall streamflow component was estimated at 2,670 cubic feet per second for the aquifer basin.A snowpack loss component was determined from a relation of April 1 water content and a corresponding relation of average basins mean annual winter precipitation. The snowpack loss component was derived.
