Tools

Various Federal, State, and local governmental entities and non-profit organizations have developed tools to assist in water resource management and stormwater planning efforts.  The tools that have been developed provide assistance with calculating runoff, estimating cost of green infrastructure, determining land use best management practices for the protection of aquatic resources and much more.  Links to various tools are provided here:

     

EPA Stormwater Calculator

EPA’s National Stormwater Calculator is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States (including Puerto Rico). Estimates are based on local soil conditions, land cover, and historic rainfall records. It is designed to be used by anyone interested in reducing runoff from a property, including a) site developers, b) landscape architects, c) urban planners, and/or d) homeowners.

Additional EPA Green Infrastructure Modeling Tools

A range of models are available to assess the costs and environmental outcomes associated with green infrastructure approaches. Here we emphasize models that can predict the water quality and water quantity impacts of green infrastructure approaches.  A few models addressing cost, air quality, and energy consumption are also included.  Modeling approaches are arranged from simpler, less resource-intensive approaches, to more complex approaches that require greater time and expertise.

SUSTAIN

A decision support system was developed to: 1) assist stormwater management professionals in developing implementation plans for flow and pollution control to protect source waters and meet water quality goals and 2) assist watershed and stormwater practitioners to develop, evaluate, and select optimal BMP combinations at various watershed scales on the basis of cost and effectiveness.

3 Rivers Rainways Homeowner Tool

This tool is for the ALCOSAN Service area in Allegheny County.¬† The Property Owner’s Tool will help you find, select, plan, and share green projects for your property that will help reduce runoff and will improve the environmental health of our area.

USDA Web Soil Survey

Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soil survey information.

BASINS (Better Assessment Science Integrating point & Non-point Sources)

Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) is a multipurpose environmental analysis system designed to help regional, state, and local agencies perform watershed- and water quality-based studies. It was developed by the U.S. Environmental Protection Agency to assist in watershed management and TMDL development by integrating environmental data, analysis tools, and watershed and water quality models.  Through the use of GIS, BASINS has the flexibility to display and integrate a wide range of information (e.g., land use, point source discharges, and water supply withdrawals) at a scale chosen by the user.

Methods, Models, Tools, and Databases for Water Research

Researchers provide sophisticated models and tools that are widely used to manage and protect water resources across the Nation. Models provide Clean Water Act implementation assistance to regional managers, offering technical expertise for the development of pollution and waste load limits and watershed protection plans. Water tools and databases also provide key information to regulators, utilities, scientists and the public regarding pollutant sources and fate; water quality and aquatic toxicity; contaminant information; water treatment options; climate change predictions for water resources.

i-Tree

i-Tree is a state-of-the-art, peer-reviewed software suite from the USDA Forest Service that provides urban forestry analysis and benefits assessment tools. The i-Tree Tools help communities of all sizes to strengthen their urban forest management and advocacy efforts by quantifying the structure of community trees and the environmental services that trees provide.

Stormwater Manager's Resource Center

This site is designed specifically for stormwater practitioners, local government officials and others that need technical assistance on stormwater management issues. Created and maintained by the Center for Watershed Protection, the SMRC has everything you need to know about stormwater in a single site.

EPA’s Technical Tools for Watershed Management

This site provides information and tools developed by EPA to assist with the development and implementation of effective watershed management plans. It is designed for people who are involved in watershed management activities. These activities include the development and implementation of watershed plans, the analysis of data, and the implementation of management practices. Each piece of this website provides specific information or helps you perform a task.
