The Water Supply Stress Index (WaSSI) Ecosystem Services Model is an online tool that models potential impacts of climate change, land use change and water consumption alteration (i.e., population growth and water withdrawals) on flow volumes, water supply stress, and ecosystem productivity. The WaSSI Ecosystem Services Model can be used technically to model impacts in the United States, Mexico, Rwanda, and Burundi, but can also serve as an educational tool to demonstrate linkages between water use, climate change, water availability, and carbon storage.
The Water Evaluation and Planning (WEAP) System is a software tool designed to help users with integrated water resources planning. WEAP uses a GIS-based interactive platform to allow high user customization, and helps users generate, integrate, and analyze watershed-specific information related to water supply, demand, and quality, as well as ecological information.
The Alliance for Water Efficiency (AWE) Water Conservation Tracking Tool is a program that allows water utilities to analyze various water conservation strategies and design conservation programs to maximize water savings and benefits while minimizing costs. The tool operates through Microsoft Excel and integrates real data from individual water utilities, allowing personalized and standardized analyses of water savings, costs, and benefits in two different units (i.e., English and metric).
The U.S. Drought Portal is an online portal that connects users to a variety of drought-, hydrological-, climate- and climate impact-related tools, products, regional programs, and resources. User-friendly and accessible products include current drought and climate monitoring platforms (e.g., the U.S. Drought Monitor), drought impact reporting and monitoring databases (e.g., the Drought Impacts Reporter), and forecasts related to drought and other climatological conditions.
SWMM-CAT allows users to evaluate climate change impacts on stormwater runoff volume and quality, and to explore how the application of various low-impact development (LID) options can be used to alter these hydrological parameters. SWMM provides a spatial and temporal analysis of runoff quality and quantity by dividing basins into multiple sub-catchment areas and analyzing runoff at different time steps.
The USGS National Water Information System (NWIS) is an online water resources monitoring database that compiles site-based information on surface water, groundwater, water quality, and water use metrics. Within these categories, users can explore current conditions, historical trends, daily summaries, and field measurements, as well as conduct statistical analyses and examine other category-specific features (e.g., peak daily flows for surface water). Data housed on this platform are gathered from over 1.5 million USGS monitoring stations located in U.S.
The EPA Stormwater Calculator (SWC) is a desktop tool that can be used by individuals looking to reduce stormwater runoff at the local level. The SWC generates rainfall runoff volume and frequency estimates for any location in the United States or Puerto Rico using historic rainfall data, local soil properties, and land use cover inputs. Users can manipulate the land use category and evaluate how seven different green infrastructure methods can alter runoff volume and frequency on their property.
U.S. Environmental Protection Agency, states, and tribes are conducting a series of surveys of the nation's aquatic resources. Often referred to as probability-based surveys, these studies provide nationally consistent and scientifically-defensible assessments of our nation’s waters and can be used to track changes in condition over time. Each survey uses standardized field and lab methods and is designed to yield unbiased estimates of the condition of the whole water resource being studied.
