USGS Groundwater Resources Program

2008

The U.S. Geological Survey (USGS) GroundWater Resources Program (GWRP) supports applied research into the effects of climate variability on groundwater availability. The purpose of GWRP is to conduct and synthesize groundwater investigations on regional and national scales.

A Sustainable Path: Meeting Nevada's Water and Energy Demands

2008

In this report, Western Resource Advocates (WRA) assess future water demands for municipal water use, agricultural water use, and water use in electricity generation for Nevada. Under several scenarios, the water demands in each sector are projected for 2015 and 2030. The scenarios developed include alternate scenarios that demonstrate the positive impact of water use efficiency, energy efficiency, and renewable sources of energy.

Water Supply and Stress Index Model (WaSSI)

2008

WaSSI is a tool that models historical, current, and future watershed stress for a particular zip code by comparing water supply and demand. Planners can select which of two climate models to use (HadCM2SuL - warm & wet; or CGC1 - hot & dry) to assess possible effects on supply and stress created by climate change under these scenarios. WaSSI uses historical USGS or state water bureau data to estimate past demand; future demand and supply scenarios are based on modeled changes in land use, land management, population, and climate change.

Climate Change in Colorado: A Synthesis to Support Water Resources Management and Adaptation (2008)

2008

This report is a synthesis of climate change science that is important for evaluating impacts on Colorado's water resources. This document provides scientific analyses to support state and regional efforts to develop a water adaptation plan, while presenting scientific analyses on observed trends, modeling, and projections of hydro-climatic variables - including temperature, precipitation, snowmelt, and runoff. This analysis includes a record of Colorado climate that covers trends in temperature, precipitation, snow and stream flow; a section describing climate models, emissions scenarios, and downscaling; followed by climate attributions, projections, and implications for the state.

Climate and Land Use Change Effects on Ecological Resources in Three Watersheds: A Synthesis Report

August 2007

The effects of global change drivers differ by place and in scale, necessitating place-specific impacts information to enable stakeholders to respond appropriately. Place and scale also determine appropriate adaptation strategies and expected outcomes. Three watershed case study assessments were conducted to advance the capability of managers to consider climate and land use change in watershed management decisions. The case studies were of the San Pedro River Watershed, the Sacramento River Watershed, and several small watersheds in Maryland (see Related Links).

Colorado River Basin Water Management: Evaluating and Adjusting to Hydroclimatic Variability

February 2007

This brief from the National Research Council of the National Academies summarizes an assessment of existing sources of scientific information - including temperature and streamflow records, tree-ring based reconstructions, and climate model projections - and how they relate to Colorado River Basin water supplies and demands, water management, and drought.

Climate Change Impacts on Water for Agriculture in California: A Case Study in the Sacramento Valley

March 2006

This study presents an application of the Water Evaluation and Planning (WEAP) system for California's Sacramento River Basin. The WEAP modeling system was used to evaluate the impact of four future climate scenarios on agricultural water management in the region, and to investigate whether water management adaptation could reduce potential impacts. This paper demonstrates how internalizing adaptation in a model that includes both the hydrologic and water management conditions associated with climate change can help assess potential tradeoffs in multi-objective water management systems.

TreeFlow

TreeFlow is an online resource for tree-ring reconstructions of stream flow and climate. By providing a longer window into the past, tree-ring reconstructions describe the natural variability of climate (precipitation, drought) more completely than gaged records. While projected changes in precipitation may be uncertain in some area, projections for temperature changes due to climate change are highly useful and relevant when added to the range of natural flow variability seen in the reconstructions.

Aquarius: A Modeling System for River Basin Water Allocation

Aquarius is a software application developed by the Rocky Mountain Research Station of the U. S Forest Service and Colorado State University. The modeling system depicts the temporal and spatial allocation of water flows among competing traditional and nontraditional water uses in a river basin. The program can be used to determine economically efficient water destination strategies by systematically examining, using a nonlinear optimization technique, the feasibility of reallocating unused or marginally valuable water storage and releases in favor of alternative uses.
