  • (United States, California)   2001-2004
    Effects of Climate Change on Ecosystem Services in California: WEAP is used to better understand the combined effects of climate change and other stressors on the goods and services provided by aquatic ecosystems in the San Francisco Bay Watershed. Through a series of scenarios with varying climate, demographics and land use, WEAP is used to identify and evaluate the likely impacts of climate change and other stressors on the provision of aquatic ecosystem services such as water for agriculture, recreation, hydropower generation, water for municipal and industrial use, habitat function and health, biodiversity, and water purification.   http://cfpub.epa.gov/gcrp/recordisplay.cfm?deid=19886   
  • (Mexico)   1993-1994
    Water and Environment in the Rio San Juan: WEAP was used in an integrated water resources assessment of the Rio San Juan basin in Mexico, including the industrial center of Monterey. The study included the development of a supply and demand balance for the watershed, and the identification of alternative water development strategies and their environmental implications. The analysis also estimated the true cost of water in the region, reflecting opportunity costs, marginal costs, and scarcity costs.     
  • (United States, Texas)   1995
    Supply Augmentation in Texas: WEAP was used in a firm yield analysis Texas, which included an assessment of water supply augmentation through an inter-basin transfer. A WEAP based analysis determined how the existing and future supply options could be used together to maximize the system firm yield. By prioritizing the supply withdrawals between the two sources, the study predicted a ten percent increase in combined firm yield compared to original estimates which had simply added the two individual firm yields. As a result of this preliminary analysis, the region moved forward to the design stage.     
  • (United States, Southeast U.S.)   1991-1997
    Integrated Assessment of the Apalachicola-Chattahoochee-Flint River Basin: The entire Apalachicola-Chattahoochee-Flint River Basin was modeled in WEAP. The states of Alabama, Florida, and Georgia rely on the surface water and groundwater from the entire basin and conflicts are emerging between upstream and downstream users. After training in WEAP, the team analyzed water use and allocation scenarios among the states to establish sustainable and equitable allocation of the regions water resources.   Chattahoochee.pdf  
  • (United States, California)   1995
    Model Building for the Hydrologic Engineering Center: The Hydrologic Engineering Center (HEC) of the U.S. Army Corps of Engineers contracted SEI-Boston for enhancements to WEAP for use in the U.S. An international leader in water modeling, the HEC has developed numerous water resources models since the 1960s, known as the HEC model series. The HEC models have been used throughout the world. WEAP was selected for its unique design philosophy stressing integration, flexibility, and the environment. HEC has used WEAP in water resources planning cases in the United States.     
  • (United States, California)   1997-2009
    Water Planning for the State of California: The California Water Plan provides a framework for water managers, legislators, and the public to consider options and make decisions regarding California’s water future. The Plan, which is updated every five years, presents basic data and information on California’s water resources including water supply evaluations and assessments of agricultural, urban, and environmental water uses to quantify the gap between water supplies and uses. The Plan also identifies and evaluates existing and proposed statewide demand management and water supply augmentation programs and projects to address the State’s water needs. To support DWR in this effort, SEI is developing an application of the WEAP model that will be used as the analytical foundation for the California Water Plan Update process. This application will be used to conduct integrated scenarios analysis, wherein various management strategies are assessed within the context of a range of uncertainty relating to future trends in water demand and climate.     
  • (West Africa)   2002-2003

    Decision Support System for Sustainable Water Supply Planning for US Utilities: This research focuses on developing a decision support system (DSS) for three urban water utilities in the U.S. (Austin, Texas, Portland, Oregon, and Philadelphia, Pennsylvania) to facilitate long-term management of water supplies in balance with water demands, using a transparent set of tools that explicitly include analyses of the full range of issues and uncertainties that may be faced by utilities in the coming decades. WEAP is a central component of this DSS, providing a framework that is accessible to strategic planners, stakeholders and decision-makers. Two elements of this research objective distinguish this effort from the water supply planning efforts that drinking water utilities have pursued for decades: the long planning horizon and the focus on sustainability. The critical set of activities pursued by the research team in developing the Water Balance Tool centered around substantial and sustained interactions with drinking water utility planners in three test sites (Austin, Texas; Philadelphia, Pennsylvania; and Portland, Oregon) that were structured specifically to identify the features that needed to be added to WEAP in order to create a broadly useful DSS. In addition, these interactions provided the research team with a forum to test the system’s responsiveness to actual on-the-ground, long-range water supply planning challenges facing utility planners at each of the three test site locations.

    Climate Change Information To Affect Decision Outcomes In The San Francisco Bay Watershed: This project will develop a comprehensive inventory of environmental decisions related to water quality and quantity and/or aquatic species and ecosystem heath that are sensitive to climate change in this watershed. From this inventory, four case studies will be selected to introduce related climate research in an attempt to improve decision-making processes. We will seek input from participants in defining how climate change information could be used to set and attain targeted outcomes in their particular processes. We would solicit input on how DSS tools such as WEAP could be used or improved to attain desired outcomes. From the suggestions of this stakeholder dialogue, the study team will implement the recommendations into the project tools (e.g. reconfiguration of model schematic, refinement of model to reflect important components, additional climate change scenarios). The refined project tools would then be used to carry-out the analysis. As we engage the analytical process of each case study, we envision on ongoing dialogue between the study team and the decision making personnel of each case study.

  • (United States, California)   2008
    Agricultural Adaptation Strategies to Climate Change in the San Joaquin Valley, California: Under an executive order from the governor, the state of California is required to complete an assessment every two years of the impacts of climate change on California’s water supply, public health, agriculture, coastline, and forestry. Included in the assessment are reports on mitigation and adaptation strategies that may combat the anticipated negative effects of climate change. SEI was invited to participate in the most recent assessment, in 2008, and asked to evaluate the impacts of climate change on managing water supplies within the Sacramento and San Joaquin River basins, which together account for the bulk of the state’s available water supplies and irrigated land. The focus of SEI’s research was to use WEAP to assess how changes in climate may impact water supply reliability for irrigated agriculture, which represents the largest water user in the state. Since initial investigations suggested that climate change will make it increasingly difficult to meet agricultural water demands, this work was extended to consider how agricultural management practices could change in response to changing water supplies such that water shortages were minimized.     
  • (United States, Massachusetts)   2007-2008
    Application of WEAP for Holistic Water Resources Management in Massachusetts: A Pilot Study in the Town of Sharon: In making investment decisions about water supply development and wastewater management, towns in Massachusetts typically employ traditional engineering cost benefit analysis. These analyses typically externalize the costs and benefits associated with the implications of a particular plan on aquatic ecosystems. If these costs where internalized then perhaps towns would make water management decisions with less impact on the environment. SEI made some modifications to WEAP that allow for this sort of more holistic analysis and has tested the upgrade through a WEAP application in the Town of Sharon. The Commonwealth of Massachusetts will now promote WEAP to other towns in order to encourage this sort of planning.     
  • (United States, California)   2006-2008
    Eco-Regional Change in the Sierra Nevada Mountains of California Due to Climate Change and its Implications of the Management of Hydropower Facilities and Aquatic Ecosystems: The Sierra Nevada Mountain Range is the water tower of California. The accumulation of snow during the winter months, and the progressive melting of that snow during the late spring and early summer, provides a supply of water to which water management systems in California have been finely tuned. This includes a large number of hydropower facilities which provide a significant amount of power during the hot dry summer but which create many problems for the managers of aquatic ecosystems within the zone of water storage, diversion and release associated with hydropower production. The expectation in California is that climate change will result in a significant reduction in the amount of snow accumulating in the Sierra Nevada. This project is using a WEAP application of the entire Sierra Nevada Range to investigate how best to balance hydropower production and ecosystem management on an eco-regional basis in the face of climate change.     
  • (Asia: Southeast Asia)   2005-2008
    Mekong Basin Focal Project: The project aimed to articulate scientifically the extent of water-related issues influencing levels of poverty in the Mekong Basin and to specify how the Challenge Program on Water and Food (CPWF) could enable significant and measurable impacts, at basin and global scales on poverty, health and environment through improvements in water productivity and other aspects of water resource management. SEI undertook the work in collaboration with the Mekong River Commission (MRC) and Commonwealth CSIRO. Key components of the project were to: Assess the current condition of water use within the basin in both biophysical and socio-economic dimensions.

    Netherlands Climate Assistance Project-Yemen Country Support: Water resources are critically vulnerable to climate change impacts in the arid nation of Yemen, and identifying adaptation strategies to meet these challenges will be key to developing sustainable livelihoods and addressing poverty in the country. Three distinct geographic/socio-economic case study areas have been selected for stakeholder consultation and analysis and integrated modelling of water resource vulnerability, potential adaptation strategies, and resilience. For each of the case study areas, WEAP was used to develop scenarios that investigate the feasibility and impact of adaptation strategies that have been identified and prioritized by stakeholders via a multi-criteria analysis methodological tool.

    Water Poverty Modeling in the Mekong River Basin: This study assessed the current biophysical and socio-economic conditions of water use within the Mekong basin, focusing on water productivity and water poverty dimensions. Analyses will identify opportunities and risks of change in water management that will influence water poverty, with an emphasis on integrating across local to basin-wide scales. These analyses will utilize WEAP to integrate domestic, agricultural, and aquacultural water use and availability information at a basin-scale to inform development of scenarios outlined in the Basin Development Plan. Bayesian Belief Networks serve as the core of an innovative methodology to aid in determining likely livelihood impacts of proposed opportunities to increase water productivity in the basin. These impacts are measured in terms of changes to the five classes of livelihood asset profiles as defined under the Sustainable Livelihoods Framework. The study will attempt to implement a linked analytical framework incorporating the Bayesian Network, WEAP model, and the Knowledge Elicitation Tool (KnETs) to develop a robust decision support methodology for elucidating impacts and responses under a variety of water-centered livelihood strategies.

    WEAP in the Middle East and North Africa (MENA): Linking WEAP to MODFLOW and capacity building: In order to help promote integrated water resources planning in the MENA region, SEI is working closely with the Arab Centre for the Studies of Arid Zones and Dry Lands (ACSAD, based in Damascus) and the German Federal Institute for Geosciences and Natural Resources (BGR) to build capacity in the use of WEAP. In addition, in order to better address the issues in the arid regions of MENA, particularly those of groundwater, WEAP has been enhanced to dynamically link to MODFLOW, a finite difference groundwater modeling system.   http://www.bgr.bund.de/IWRM-DSS

    Innovative Management Options to Prevent Loss of Ecosystem Services Provided by Chinook Salmon in California: Overcoming the Effects of Climate Change: Chinook Salmon are the pinnacle species in the California’s riverine aquatic ecosystems. Historically these large fish spawned in most of the rivers and streams which flowed into the Pacific north Monterey Bay. Based on hydrologic and climatic conditions, individual streams accommodated genetically different salmon populations, or runs. The enormous amount of hydrologic manipulation in California over the course of over a century has lead to the decline of several of these runs, none more so than the Spring Run. Spring run salmon return form the ocean in March and April when the rivers are high and the water cold. They then swim up to deep pools where they hold over the hot Summer months before they spawn when the water cools in October or November. The extent of the spring run in California has been reduced to only a few streams, and these are a grave risk due to climate change. This project will use a WEAP application linked to model of salmon life cycles to investigate what management options are open to manage Spring run Chinook salmon and the implications for the total ecosystem if this pinnacle species is lost.

    Sharpening Drought Plans to Consider Climate, the Watershed, the Regulatory Environment, and the Forces of Change: SEI has established collaboration with the El Dorado Irrigation District, a water purveyor on the western slope of the Sierra Nevada Mountains, to investigate the potential impacts of climate change on a water system that depends to a large degree on the accumulation of snow at high elevation during the winter and the progressive melting of this snow during the late spring and early summer. A WEAP application of the system has already been developed in order to test drought management triggers and actions that were defined by the district assuming that historic hydrologic patterns will be representative of future conditions. Climate change calls this assumption into question. This project will attempt to help introduce notions of uncertainty and risk management into the definition of drought plan triggers and actions adopted by the district, as well as other long-term actions being contemplated by the district.     
  • (Peru)   2008-2009
    Water Management Adaptation to the Loss of Glaciers in the Andes of Peru: This project focuses on assessing potential changes in the watersheds of the Andes Mountains in Peru associated with the loss of glaciers due to climate change. An effort is underway to develop a module within WEAP that represents the evolution of glaciers under different future climate scenarios. This module will be used to developed WEAP applications of three Peruvian watersheds: the Santa; the Rimac; and the Mantaro. These applications will be run using climate scenarios developed for the region to investigate the water management implications of the loss of glaciers and possible water management adaptations.
