H14B:
Drought, Groundwater Management, and Long-Term Groundwater Sustainability in the Western United States: Assessment, Monitoring, Modeling, Planning, Management, and Policy I


Session ID#: 10585

Session Description:
Much of the Western United States has been in a long-term drought or series of multi-year droughts throughout the past two decades, a period that has also experienced significant shifts in urban, industrial, and agricultural water uses leading to unprecedented pressures on groundwater resources. This session examines drought impacts on groundwater resources, groundwater management, regional and state policy responses and implementation in the Western U.S., including implementation of the new Sustainable Groundwater Management Act of California. We invite studies that showcase innovative approaches to groundwater basin assessment, monitoring, modeling, and management under climate uncertainty, drought, and a changing water infrastructure landscape in the semi-arid Western US; analyze policy responses, effectiveness of management measures; evaluate best management practices for groundwater management agencies; define operational sustainability criteria for groundwater basins; and review roles of data collection, monitoring, and modeling/assessment.
