IDS AWAS - Alluvial Water Accounting System

AWAS can calculate river depletions using the Stream Depletion Factor method (Jenkins, 1968) or the The Analytical Stream Depletion method developed in 1987 by Dewayne R. Schroeder. The latter method uses analytical equations described by Glover (Glover, 1977) and others. The AWAS model can calculate depletions using daily or monthly time steps. The user has the option to evaluate a number of different boundary conditions: alluvial, infinite, no flow, and effective SDF. Model input for AWAS can either be in the form of pumping records for each well consisting of a pumping rate and duration or net consumptive use or recharge in a daily or a monthly time step. Year type can be set to calendar, irrigation, or USGS. Data can be projected into the future or past based on historical records, and the effect of turning off the well by specifying an end date beyond the period of record can be simulated.
