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.
The Local Climate Analysis Tool (LCAT) allows users to explore local climate variability in relation to global climate trends and to investigate the linkages between local climate, weather, and water events. Intended to enhance local climate expertise of National Weather Service (NWS) staff, LCAT analyzes available climate data sets (provided and recommended by NOAA) via the NWS Virtual Lab platform, helping users conduct local climate or correlation studies through a scientifically credible process.
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).
i-Tree, developed by the U.S. Forest Service, is a peer-reviewed software bundle that facilities maximizing benefits from urban forestry efforts. i-Tree provides a variety of analysis tools, including urban forest ecosystem services and aesthetics benefits analyses, planting scenario evaluations, and canopy cover analyses. One tool, i-Tree Hydro, which is currently available only in a beta version, is of particular relevance to water resources management.
Flood Resilience: A Basic Guide for Water and Wastewater Utilities is an interactive PDF that can guide water utility managers through a flood risk reduction planning process. This digital resource, complete with worksheets, videos, and examples, takes managers through a four-step process to evaluate and enhance flood resilience of utility infrastructure and facilities. Steps include: identifying flood threats, evaluating vulnerable utility infrastructure and consequences of flooding, evaluating flood mitigation options, and developing a flood mitigation implementation plan.
