An Introduction to Adaptation in the Water Sector
Climate change is changing our assumptions about water resources. As climate change warms the atmosphere, altering the hydrologic cycle, changes to the amount, timing, form, and intensity of precipitation will continue. Other expected changes include changes in stream flow and water supply, as well as the quality of aquatic and marine environments. These impacts are likely to affect the programs designed to protect water quality, public health, and safety.
Use the resources below as a starting point to better understand how climate change will affect the water sector.

Climate Resilience Evaluation and Awareness Tool (CREAT) 3.0
This risk assessment tool assists drinking water, wastewater, and stormwater utility owners and operators in understanding potential climate change impacts to the water sector; assessing related risks at their utilities; and evaluating adaptation options. CREAT allows users to perform these analyses using scenario-based decision making in multiple time periods using pre-loaded data and downscaled local climate information. CREAT can support utilities in initiating adaptation planning and provides suggested customizable adaptation strategies that can be implemented at the user’s utility.

Shifting Course: Climate Adaptation for Water Management Institutions
November 2011
This publication identifies a set of common principles for climate-adaptive institutions, specifically for water management. It was originally inspired by a session organized by the World Wildlife Fund (WWF), International Union for Conservation of Nature and Conservation International at the 2010 Stockholm World Water Week. This report is a provides operational guidance on how to make water management institutions more climate-adaptive. Although the climate debate is often centered on temperature, water is what will determine whether a community (a village, city, or region) or ecosystem can survive - according to the report.

Getting Climate Smart: A Water Preparedness Guide for State Action
April 22, 2013
This state action guide was developed by the Natural Resources Defense Council (NRDC) and American Rivers to provide water managers and state governments with information to help comprehensively plan and prepare for the water-related impacts of climate change. The guide combines practical advice and real-world case studies while outlining a six-step planning process for state governments, water managers, and other stakeholders to develop and implement climate preparedness plans.

Innovative Approaches for Adapting to Water Variability in the West
May 2012
This brief reviews three approaches that communities are pursuing to adapt to climate change:
- New Mexico's Active Water Resource Management program, which put rules into place that allow for temporary water use changes in real time in case of drought.
- The Water Utility Climate Alliance (WUCA), which was founded by water managers concerned by a gap in climate assessment and adaptation science needed to support their decisions.
- Colorado's Joint Front Range Climate Change Vulnerability Study, which brings together the state and water utilities to assess climate change's impact on local water availability.

Climate Change Handbook for Regional Water Planning
November 2011
Developed cooperatively by the California Department of Water Resources (DWR), the U. S. Environmental Protection Agency, Resources Legacy Fund, and the U. S. Army Corps of Engineers, this handbook provides a framework for integrating the impacts of climate change into water resources management. Key decisions, resources, tools, and planning options are presented to guide resource managers and planners as they develop means of adapting their programs to a changing climate. The handbook uses CA DWR's Integrated Regional Water Management (IRWM) planning framework as a model into which analysis of climate change impacts and planning for adaptation and mitigation can be integrated at a regional scale.

EPA National Stormwater Calculator
2014
The U. S. Environmental Protection Agency (EPA) National Stormwater Calculator (SWC) is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States (including Puerto Rico). The SWC is a simple to use tool for computing small site hydrology by estimating the amount of stormwater runoff generated from a site under different development and control scenarios over a long term period of historical rainfall. The analysis takes into account local soil conditions, slope, land cover and meteorology.

EPA Climate Ready Estuaries - Synthesis of Adaptation Options for Coastal Areas
January 2009
This 2009 report by the U. S Environmental Protection Agency (EPA) provides an overview of climate change impacts on coastal areas and presents adaptation options relevant to various estuarine management goals, including: maintaining/restoring wetlands, maintaining sediment transport, preserving coastal land and development (including infrastructure, maintaining shorelines (hard and soft measures), managing invasive species, preserving habitat for vulnerable species, maintaining water quality, and maintaining water availability.

Adaptation Case Studies in the Western United States
October 31, 2011
From the Georgetown Climate Center, this report contains two case studies from the Western United States that explore water shortages in the West, water rights along the Colorado River, and the protection of an endangered ground-dwelling bird: the greater sage grouse. In doing so, the report also examines the role of states in adaptation planning and the intersection between state and federal authority.

EPA Climate Change and Water Website
The U. S. Environmental Protection Agency's (EPA) Office of Water Climate Change page provides links to resources that can be used to learn more about current climate-related activities within the agency and beyond. One key document provided on the site is the National Water Program Strategy: Response to Climate Change which provides an overview of the likely effects of climate change on water resources and the nation's clean water and safe drinking water programs. Links to newsletters, meeting calendar, and other climate information from EPA are provided.
