AbstractNew and growing demands to finite and fully allocated water resources in the semi-arid southwestern United States mean that existing water resources must be managed with increasing efficiency to minimize shortages and associated social conflict. Computer based simulations can provide a powerful tool to aid in policy related decisions. This dissertation describes the development of a simulation model of the Rio Grande surface water and groundwater system for use in scenario evaluation. The primary model goal is to integrate cross disciplinary science at a basin scale, and make it easily accessible to a wide range of stakeholders. To achieve this at a river basin scale, three existing groundwater models and one surface water model were simplified and combined in a system dynamics framework using the commercial software package Powersim Studio 2005. To this physical model, a simple human behavioral model and user interface was added. The resulting scenario evaluation tool runs 40 year simulations on a laptop computer in tens of seconds, with inputs that are easily changed by non-expert users via a graphic, user friendly interface.
