Tidal Flooding

Tool Overview: 

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.

Storm Water Management Model Climate Adjustment Tool (SWMM-CAT)

Tool Overview: 

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.

National Stormwater Calculator

Tool Overview: 

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.

Georgia Water Toolkit


United States
33° 3' 50.1264" N, 83° 16' 34.9212" W
Georgia US
Tool Overview: 

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.

Flood Resilience: A Basic Guide for Water and Wastewater Utilities

Tool Overview: 

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.

Flood Inundation Maps

Tool Overview: 

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.

Drought Management Database

Tool Overview: 

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.

Coastal Flood Exposure Mapper

Tool Overview: 

The Coastal Flood Exposure Mapper helps communities understand their risks and vulnerability to coastal flooding. The mapper was first developed following Hurricane Sandy to provide a tool to show areas susceptible to coastal flooding, storm surge, and inundation, and to inform communities and local authorities about the risks their communities face. Users are able to explore maps that show how natural resources, communities, and infrastructure and development will be exposed to coastal flooding hazards.

Coastal County Snapshots

Tool Overview: 

Coastal County Snapshots is an online tool that produces user-friendly reports identifying and describing three categories of coastal hazards and change — flooding risk, wetland impacts, and ocean jobs impact — for selected coastal counties in the United States. Users select a coastal county, and the tool generates reports for the three categories identifying and describing changes that have occurred (e.g., changes in land cover, job trends) and important sectoral information (e.g., amount of coastal infrastructure at risk from flooding, how wetlands can be used to reduce flood impacts).

Tool Description: 

Land managers, natural resource managers, local authorities, planners, engineers, scientists, community members

Coastal Community Resilience Index

Tool Overview: 

The Coastal Resilience Index (CRI) is a self-assessment tool, in worksheet form, that evaluates community storm preparedness and recovery potential. Designed for quick and easy use by community leaders, the CRI guides discussion and self-assessment of important coastal assets — including infrastructure and facilities, transportation, community plans, mitigation measures, business plans, and social systems — in relation to self-defined storm scenarios, facilitating identification of areas where community resilience could be bolstered.
