Flowing Towards a Sustainable Future

Introducing WaterFALL®, a groundbreaking hydrologic modeling tool that combines cutting-edge science with the power of nature to simulate daily streamflow and water quality, offering invaluable insights for evaluating the impact of nature-based solutions and other management options on watershed sustainability under current and projected future scenarios.

Unleash WaterFALL for Enhanced Watershed Management

Comprehensive Watershed Analysis
Simulate daily streamflow at the catchment scale, evaluating runoff dynamics, surface storage, and subsurface processes.

Human Impact Consideration
Account for human alterations to the hydrologic network, including point sources, withdrawals, and reservoirs.

Water Quality Insights
Simulate sediment, nitrogen, and phosphorus loadings, both locally and cumulatively, from man-made and natural sources.

Nature-Based Solutions Modeling
Represent the effects of nature-based solutions within watershed modeling, enabling assessments for flood resilience.

Interactive Watershed Planning with WaterFALL

NBS Explorer for Louisiana

The first release of the NBS Explorer web application provides stakeholders within Louisiana the ability to evaluate nature-based solutions projects under current and projected scenarios across the flowing waters of the state.

Underlying WaterFALL model calibrated for streamflow and water quality to observations across 25 gages in over 30 basins within the state.
Mapping interface allows users to select specific stream reaches in which to implement one of over 22 different NBS practices across five NBS types (restoration, preservation, agricultural conservation, green infrastructure, and protection of wetland migration corridors).
On demand modeling evaluates the user defined project for both flood resilience and co-benefits including reduction in water quality loads, impacts to aquatic habitat health, and tracking of local and downstream social vulnerability characteristics.

Tailored solutions for clients of all sizes

Depending on a client's needs, RTI can use WaterFALL as a project tool to create customized analyses of watersheds, provide a calibrated set of models in a desktop application to allow clients to conduct their own analyses, or deploy one of our existing or customized web application interfaces into web WaterFALL to allow clients to conduct modeling analyses without modeling know-how.

Clients include:

NGOs

(TNC, EDF, WRF)

Government

(USEPA, USFWS, NCDEQ, LWI)

Utilities

(Exelon Corporation, Charlotte Water)

What our clients are saying

I am grateful for the hard work that has been poured into this project for the Village of Natchez. It is devastating every time we experience a flood because the folks who live within the city limits of Natchez are underserved residents who cannot afford flood insurance, old residents, and others who have no options or funds to be able to replace things once they experience a flood. Then they are stuck in living in a home that potentially has mold and other issues, which creates great concern for their overall health and quality of life.

—Monique Hamilton-Sarpy
Alderman for the Village of Natchez

The NBS Explorer Tool has been useful for Moncus Park in that it allows us a clear method of communicating our "green" approaches to stormwater management as a park conservancy. It also provides us with valuable data to communicate our impact as not only a public amenity, but as a functional space for flood mitigation and community resilience building.

— Abbie Judice Acosta
Conservation Director for Moncus Park
