Watershed Central, run by the U.S. Environmental Protection Agency (EPA), is an online portal that houses a large variety of information related to watershed management. Useful for regional, state, and local officials as well as the public, Watershed Central provides links to resources, tools, data, guidance, funding recommendations, training opportunities, and online support communities focused on developing and implementing comprehensive watershed management plans.
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.
WEPPCAT is a free, online erosion simulation tool that allows users to analyze potential stream sediment loading in response to various climate change and land management scenarios. WEPPCAT leverages the existing USDA Water Erosion Prediction Project (WEPP) Model, but has additional features that allow analysis of climate impacts and various land management practices on soil yield and loss.
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.
Tidal Flooding is an educational, online, narrated presentation provided by the NOAA Office for Coastal Management that describes tidal flooding and the risks communities may face with increased tidal flooding from heavy rains, sea level rise, and continued coastal development. The presentation outlines the formation of extreme high tides, potential impacts of extreme high tides, and how flooding will change with sea level rise.
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 Soil Climate Analysis Network (SCAN) is a network of monitoring sites established in agricultural and other areas across the United States. Soil moisture, soil temperature, precipitation, wind, and soil radiation data from these sites is collected, compiled, and presented via the online SCAN mapping tool. Using the mapping tool, users can access and explore real-time and recorded hydrological and climatological trends taking place in various areas of the county.
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.
