A Sustainable Path: Meeting Future Water and Energy Demands in the Arkansas River Basin - Executive Summary

2009

This Executive Summary outlines strategies for municipalities and the energy sector within the Arkansas River Basin to meet growing water use demands while conserving the Basin’s natural resources. The Arkansas River is a major tributary of the Mississippi River which traverses Colorado, Kansas, Oklahoma, and Arkansas. The river's initial basin starts in Colorado, specifically the Arkansas River Valley, where the headwaters derive from the snowpack in the Collegiate Peaks.

Climate Change Impacts on Water Management and Irrigated Agriculture in the Yakima River Basin, Washington, USA

2009

Utilizing a multi-model ensemble approach of downscaled climate model projections, hydrologic modeling, and water management models, this report presents results for changes in reservoir levels and snow pack in the Yakima River basin and resulting impacts to irrigated agriculture in the basin. The paper presents the analysis of  hydrological conditions and how climate change is projected to impact water supply for water users with junior water rights and - in the extreme years - users with senior water rights throughout the basin.

Assessing Reservoir Operations Risk Under Climate Change

April 11, 2009

A collaborative effort of the Bureau of Reclamation, USGS, USACE, and the California Dept. of Water Resources, this paper presents a flexible methodology for conducting climate change risk assessments involving reservoir operations.   The risk-based framework described in this paper provides a new context for climate change assessments. It is a flexible framework that advances methods for assessing scenario-impacts and/or characterizing uncertainties about projection scenarios or associated impacts.

Green Infrastructure for Los Angeles: Addressing Urban Runoff and Water Supply through Low Impact Development

April 17, 2009

This report was designed to help the City of Los Angeles use low impact development (LID) techniques to address water quality, flood control, and climate change issues. LID is a strategy for managing stormwater runoff that uses natural drainage features to capture and filter urban runoff. From an environmental standpoint, LID reduces water pollution, replenishes aquifers, and encourages water reuse. From an adaptation standpoint, LID reduces stress on water supply and can provide shade trees, helping to reduce urban heat islands.

Using Future Climate Projections to Support Water Resources Decision Making in California

May 2009

This paper presents advances in climate projection information that the California Department of Water Resources has made since their 2006 report, "Progress on Incorporating Climate Change into Management of California's Water Resources. " These advances include an improved understanding of how well selected climate models represent historical climate conditions and refined methodologies for representing stream flows, outdoor urban and agricultural water demands, and sea-level rise in planning tools, in order to assess their usefulness in decision making for water resource managers.

USGCRP Global Climate Change Impacts in the U.S. - Water Resources

June 2009

This report is one of seven sector-specific chapters from the United States Global Change Research Program's comprehensive 2009 National Climate Assessment, "Global Climate Change Impacts in the U. S. "  The 'Water Resources' chapter synthesizes current and projected impacts to the U. S. water cycle from climate change. Changes to the water cycle identified in the report include: changes in precipitation patterns and intensity, changes in the incidence of drought, widespread melting of snow and ice, increasing atmospheric water vapor, increasing evaporation, increasing water temperatures, reductions in lake and river ice, and changes in soil moisture and runoff.

Emerging Climate Change Impacts on Freshwater Resources: A Perspective on Transformed Watersheds

June 2009

This report discusses the increasing effects of climate change on freshwater resources and ecosystem services. It focuses on types of socioeconomic and biotic adaptations, and provides an overview of direct and cumulative impacts.   Perspectives on adaptive responses are offered, and the results of five case studies are included which demonstrate regional adaptation measures. The series of case studies - from Massachusetts, New York, Georgia, Florida, Colorado, and California - are used to illustrate ecosystem services that are able to adapt to to extreme variations in precipitation.

Options for Improving Climate Modeling to Assist Water Utility Planning for Climate Change

December 2009

This report, which was commissioned by the Water Utility Climate Alliance (WUCA), considers how federal investments in the science of climate change, and in particular climate modeling, can best be directed to help improve the quality of  research so that it may be more useful to water utilities and other possible users in adapting to climate change.   It explains how climate models work, describes how some WUCA members have used climate models and downscaling to assess impacts on their systems and develop adaptation options, and makes seven initial recommendations for how climate modeling and downscaling techniques can be improved so that these tools and techniques can be more useful for the water sector.

Decision Support Planning Methods: Incorporating Climate Change Uncertainties into Water Planning

January 2010

The Water Utility Climate Alliance (WUCA) developed this white paper to present multiple-outcome planning techniques to water utilities interested in incorporating climate change into their planning. Many water utilities currently are engaged in, or considering, vulnerability assessments and will be seeking guidance on how to incorporate the large range of new information into their planning. This white paper is intended to guide those wanting to move forward with the adaptation process.
