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 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.
The atlas serves as an information sharing tool for communities and organizations interested in implementing low-impact development projects and addressing stormwater and growth-related issues that impact water quality. The tool allows user to enter data regarding existing low-impact development projects. These projects are displayed on a regional map that shows existing projects and provides information about the project type (e.g., swale/bioswale, permeable pavement, water conservation), location, land use type, construction date, and links to additional information about the project.
The Inundation Analysis Tool is a web-based tool that analyzes how frequently and for how long high tide events have historically occurred, allowing users to better understand saltwater inundation and flooding trends for certain elevations and locations. Users select the site (must be a NOAA CO-OPS tide station), time period of interest, and the elevation for inundation pattern analysis (e.g., mean high water, mean tide level).
This web-based toolkit is designed to help local water managers understand and address water management challenges related to climate change, urban development, pollution, interstate water rights, and more. It highlights key issues as well as providing access to the most current regulatory, educational, and decision support information, as well as discussing funding opportunities. It was developed for the State of Georgia.
The NWS Flood Inundation Map is an online tool that identifies the extent and severity of flood risk for a given location. Users select from a variety of national river gauges to view flood risk at a specific location. For a given area, users can explore and map three different types of flood data: inundation, flood categories, and current flood forecast.
The USGS Flood Inundation Mapper is an online flood mapping tool. Once a community develops a flood inundation map library through a collaborative effort with USGS, inundation maps are uploaded to the web-based mapper for broader viewing and access. Users can select a specific location and explore several different data sets, including current stream conditions, the estimated extent of historic flood events, and theoretical flooding scenarios.
The Drought Management Database collects and provides examples of how different U.S. regions and sectors are responding to and mitigating drought. This online database can be useful for various levels of government looking to engage in drought preparedness and response planning, as well as for sectoral decision makers looking to undertake similar planning efforts, as it provides real-world examples and lessons learned.
