With the threat of global warming and ever-increasing demand for a limited resource, accurate accounting of surface water and ground water in arid environments is more important than ever. Numerical models are increasingly being used in the quantitative evaluation of availability, vulnerability, and sustainability of surface water and ground water resources. Models provide valuable insight into the surface water/ground water interaction and provide the user with methods for understanding impacts of future development and allocation. Global warming introduces additional uncertainty to the forecasts that may be best addressed with models. This session studies models evaluating these applications in arid environments: regional models for water use/consumptive use permits; estimating natural recharge and sustainable yield (safe yield); artificial recharge via infiltration basins and recovery; aquifer storage and recovery (ASR) via injection/recovery wells; and incorporating climate change effects into water resource planning.
