Brian's research focuses on developing decision support tools for evaluating various operational strategies in managed water resources systems. He has participated in the development and application of databases and tools used for water resources analysis in a variety of domestic and international settings. Prior to joining SEI-US, Brian worked at the Natural Heritage Institute, where his research focused on defining creative strategies for balancing agricultural, urban and environmental water demands in managed water resources systems. He has worked extensively with the water resource systems simulation model of the California water system used by government agencies for statewide integrated water planning. Brian has used this model to investigate groundwater banking and conjunctive use potential, and to identify promising operational flexibility to enhance river flows for fish and riparian habitat restoration. His other research includes developing management practices to mitigate water and pesticide runoff from orchards. Brian received his Ph.D. in hydrologic sciences from the University of California, Davis in 2005.

Analysing stakeholder driven scenarios with a transboundary water planning tool for IWRM in the Jordan River basin

In: Integrated Water Resources Management: Concept, Research and Implementation, pages 413-433

Author(s): Bonzi, C. ; Joyce, B. ; Onigkeit, J.; Hoff, H.; Tielbörger, K.
Year: 2016

Research Area(s): Water Resources

Description: This book chapter presents the application of a transboundary spatially explicit water resources simulation and planning tool in support of decision-making in a contentious setting. Although integrated water resources management (IWRM) has become the mainstream concept for water management, its implementation in transboundary, politically tense settings, such as the Jordan River basin, is still limited. In this study, the authors integrated socio-economic scenarios and water management strategies resulting from a stakeholder process, thereby including socio-economic uncertainty, using the WEAP modelling software. Tool development was supported by an active transboundary dialogue between scientists and stakeholders.

Evaluating Resource Management Strategies for Update 2013 of the California Water Plan

Proceedings of the World Environmental and Water Resources Congress 2013, 2391-2403

Author(s): Bloom, E. ; Joyce, B. ; Yates, D. ; Draper, A.; Groves, D.; Juricich, R.; Rayej, M.
Year: 2013

Research Area(s): Water Resources

Description: This paper describes the analytical approach developed by the California Department of Water Resources (DWR) to evaluate the performance of alternative regional resource management strategies in meeting future water management objectives as part of the 2013 Update of the California Water Plan. The plan, mandated by state law and updated every five years, is used to guide regional and statewide water policy decisions. It has identified 30 resource management strategies that California's regions can invest in to help reduce water demand, improve operational efficiency and water transfers, increase water supply, improve flood management, improve water quality, and practice resource stewardship. The evaluation of these strategies in Update 2013 will provide decision support and guidance to California's regions and the State legislature.

Irrigation demand and supply, given projections of climate and land-use change, in Yolo County, California

Agricultural Water Management 117, 70-82

Author(s): Mehta, V. ; Joyce, B. ; Purkey, D. ; Haden, V.R.; Jackson, L.E.
Year: 2013

Research Area(s): Water Resources

Description: This article assesses the potential effects of climate change and adaptive management on irrigation water supply in the Cache Creek watershed in California. The authors built a model using the Water Evaluation And Planning (WEAP) system, and calibrated it using historical data (1971-2000) on streamflow, irrigation deliveries, and reservoir operations. Results show irrigation demand increasing by 26% and 32% under B1 and A2 baseline climate scenarios respectively in the latter part of the century. Increases in demand from climate change alone exceed applied water reductions from changing cropping patterns by an order of magnitude. Maximum applied water savings occur by combining a diversified water-efficient cropping pattern with irrigation technology improvements.
