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.
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 Federal Support Toolbox is an online portal that connects and provides resources for individuals interested in or working on water resources issues in the United States and abroad. The toolbox is a useful resource for all phases of adaptation, as well as for visitors from different sectors. This toolbox facilitates both education and collaboration among the water resources community.
Extreme Water Levels in an online product that allows users to analyze the likelihood that local tides will exceed a given elevation (mean high or low water) at different monthly and yearly time scales. Extreme Water Levels calculates these likelihoods based on over 30 years of monitoring data, and provides viewers with a rough idea of extreme tide heights expected every year, every other year, every 10 years, and every 100 years.
The Drought Risk Atlas is an online visualization tool that allows users to analyze and compare historical and contemporary droughts at the local level to better understand drought risk. The atlas allows users to explore past drought characteristics for specific geographic regions by compiling data from numerous monitoring stations; users can select a monitoring station within their area, as well as select other stations that exhibit similar precipitation patterns.
