Jack Sieber is a Senior Scientist at SEI, developing computer-based tools to assist in long-range scenario planning, and working with researchers, policy makers and other stakeholders to help build a path to a sustainable future. Currently, his work focuses on integrated water resources planning at the watershed scale, with a special focus on the potential impacts of climate change. He is the developer of WEAP, the Water Evaluation And Planning system. Jack received an M.S. in Computer Science from Yale University in 1988.

Simulating High Elevation Hydropower with Regional Climate Warming in the West Slope Sierra NevadaJournal of Water Resources Planning and Management, online first Author(s): Rheinheimer, D. ; Sieber, J. ; Mehta, V. ; Viers, J. ; Kiparshy, M.; Ligare, S.Year: 2013 Research Area(s): Water Resources Description: This article describes the development of a water resources management model for the upper west slope Sierra Nevada to understand the potential effects of regional climate warming on hydropower at the watershed scale, and the results of that model. Water systems in snowmelt-dominated hydro-regions such as California's Sierra Nevada mountains are sensitive to regional climate change, hydropower systems in particular. The authors developed a water resources management model for the upper west slope Sierra Nevada to understand the potential effects of regional climate warming on hydropower at the watershed scale. The model was developed with the Water Evaluation And Planning system (WEAP) and includes most water management infrastructure in the study region. The study found that the highly productive northern Sierra Nevada would see large reductions in hydropower generation due to decreases in annual runoff related to climate change.More information External Link |

Climate Driven Water Resources Model of the Sacramento Basin, CaliforniaJournal of Water Resources Planning and Management 135:5, 303-313 Author(s): Yates, D. ; Purkey, D. ; Sieber, J. ; Young, C. ; Joyce, B. ; Huber-Lee, A.; Galbraith, H.; West, J. Herrod-Julius, S.; Rayej, M.Year: 2009 Research Area(s): Water Resources Description: An integrated modeling framework for addressing water resource planning and management issues in the Sacramento Basin, USA based on the Water Evaluation and Planning model Version 21 (WEAP21). WEAP21 provides a seamless integration of both the physical hydrology of the region and the water management infrastructure that governs the allocation of available water supplies to meet the range of different water demands.More information External Link |

Climate Warming, Water Storage, and Chinook Salmon In California's Sacramento ValleyIn Climatic Change, Vol.91, Issues 3-4 Author(s): Yates, D. ; Purkey, D. ; Sieber, J. ; Joyce, B. ; Galbraith, H.;Huber-Lee, A.;West, J.; Herrod-Julius, S.Year: 2008 Research Area(s): Water Resources Description: The Chinook salmon (Oncorhynchus tshawytscha) spawns and rears in the cold, freshwater rivers and tributaries of California's Central Valley, with four separate seasonal runs including fall and late-fall runs, a winter run, and a spring run. Dams and reservoirs have blocked access to most of the Chinook's ancestral spawning areas in the upper reaches and tributaries. Consequently, the fish rely on the main stem of the Sacramento River for spawning habitat. Future climatic warming could lead to alterations of the river's temperature regime, which could further reduce the already fragmented Chinook habitat.External Link |

Relations Among Storage, Yield and Instream FlowWater Resources Research. Author(s): Vogel, R ; Sieber, J. ; Archfield, S.; Smith, M.; Apse, C.; Huber-Lee, A.Year: 2007 Research Area(s): Water Resources Description: This study adapts the existing generalized water evaluation and planning model (WEAP) to enable general explorations of relations between reservoir storage, instream flow, and water supply yield for a wide class of reservoirs and operating rules.Download PDF |
