Studies

(FPMS) Floodplain Management Services: Through the FPMS program, the Corps provides information on flood hazards to local interests, state agencies, and other federal agencies to guide development of the floodplains of the rivers of the United States. Hydraulic & Hydrology Studies proposed with USACE for 2024

Fourpole Creek Watershed- Huntington and Cabell County Completed September 2022

The Fourpole Creek watershed experiences frequent flooding in the Huntington, WV, area with impacts to residential and commercial properties, roads, utilities, and recreation facilities. Flooding within the watershed has been studied by multiple organizations since the 1960s. This study was conducted by the US Army Corps of Engineers under the Flood Plain Management Services program, to assist State, County and local government officials make informed decisions to address flood risks within the watershed. This effort is focused on the development of comprehensive hydrologic and hydraulic modelling which provides data on peak discharges during storm events of varying frequencies, resulting water surface profiles and geographic extent of flooding. The modelling includes evaluation of existing infrastructure which may be affecting water surface elevations such as culverts and bridges. The modelling also evaluates the hydrologic effect of a conceptual detention structure and evaluated its potential to reduce flooding impacts.

Left Form Marrowbone Creek Watershed- Kermit, Mingo County Completed December 2023

The primary purpose of this study was to examine conceptual structural mitigation measures for managing flood risk and associated impacts of stormwater flooding within the Left Fork Marrowbone Creek Watershed, which is located in Mingo County, West Virginia. This study was conducted in cooperation with the West Virginia State Resiliency Office (WV SRO) and West Virginia Voluntary Organizations Active in Disasters (WV VOAD). This watershed was identified by WV SRO and WV VOAD as an area to do preventative flood risk mitigation. This study is intended to be a pilot study for other areas in West Virginia with similar topography and flood risk.

The City of Madison, WV experiences frequent flooding from the Little Coal River in addition to local runoff from surrounding hills with impacts to residential and commercial properties, community facilities, roads, and schools. Under the Floodplain Management Services Program, the US Army Corps of Engineers analyzed and evaluated potential flood risk management measures to help reduce the risk associated with flooding in the watershed, specifically in the Madison area. This effort is focused on the development of hydrologic and hydraulic modeling which provides data on peak discharges during storm events of varying frequencies, resulting water surface profiles, and geographic extent of flooding. This includes evaluation of existing infrastructure such as culverts, which may affect water surface elevations. Furthermore, the modeling investigates the hydrologic effect of a conceptual detention structure and its potential to reduce flooding impacts.

The City of St. Albans, WV, experiences frequent flash flooding that overwhelms their existing municipal stormwater system resulting in flooding impacts to residential and commercial properties, community facilities, roads, and utilities. In an effort to identify potential flood risk management measures the U.S. Army Corps of Engineers conducted a technical study under the Floodplain Management Services program that analyzed flood sources upstream of the existing municipal stormwater system. The study developed a comprehensive hydrologic and hydraulic model of watersheds upstream of the stormwater system at St. Albans City Park and Cunningham Memorial Park. Through modeling analysis, the study produced water surface profiles upstream of the stormwater system for select storm event frequencies. Lastly, the study evaluated conceptual structural measures to reduce the peak volume and slow the release rate of runoff into the stormwater system and the tributary that the stormwater system flows into.

The Feasibility Study is the first stage of development for a potential Federal water resources development project. The purpose of the feasibility study is to identify, evaluate and recommend to decision makers an appropriate, coordinated, and workable solution to identify water resources problems and opportunities. The following three-year studies are currently underway:
