Biography
Dr. Sampson is a systems analyst and process modeler; David creates and links algorithms (problem-solving instruction sets) that mimic social and biological processes of interest to water managers and stakeholders. These computer simulation tools permit real-time analyses of future, probable events and the social/ political responses to these trigger mechanisms (and potential ramifications). A recent project funded by the National Commission on Energy and Policy, in conjunction with Portland State University, evaluated the expected water and energy use for the Phoenix Metropolitan Area (and short-falls) under climate change. His current research focuses on the development and implementation of an urban water policy and planning tool labeled WaterSim 5, an open source software program that can be used by students, faculty, and water resource managers to examine tradeoffs in water governance and planning strategies for Central Arizona communities.Expertise
