The United States Army Corps of Engineers (USACE) is a direct reporting unit and engineer formation of the United States Army that has three primary mission areas: Engineer Regiment, military construction, and civil works. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the chief of engineers/commanding general. The chief of engineers commands the Engineer Regiment, comprising combat engineer, rescue, construction, dive, and other specialty units, and answers directly to the Chief of Staff of the Army. Combat engineers, sometimes called sappers, form an integral part of the Army's combined arms team and are found in all Army service components: Regular Army, National Guard, and Army Reserve. Their duties are to breach obstacles; construct fighting positions, fixed/floating bridges, and obstacles and defensive positions; place and detonate explosives; conduct route clearance operations; emplace and detect landmines; and fight as provisional infantry when required. For the military construction mission, the chief of engineers is directed and supervised by the Assistant Secretary of the Army for installations, environment, and energy, whom the President appoints and the Senate confirms. Military construction relates to construction on military bases and worldwide installations.

The Rough River is a 136-mile-long (219 km) tributary of the Green River in west-central Kentucky in the United States. It's located about 70 miles southwest of Louisville, and flows through Breckinridge, Hardin, Grayson, and Ohio counties. Via the Green and Ohio rivers, it is part of the watershed of the Mississippi River. According to the Geographic Names Information System, it has also been known historically as "Rough Creek". In the 1950s it was dammed, creating Rough River Lake.
An hydrological transport model is a mathematical model used to simulate the flow of rivers, streams, groundwater movement or drainage front displacement, and calculate water quality parameters. These models generally came into use in the 1960s and 1970s when demand for numerical forecasting of water quality and drainage was driven by environmental legislation, and at a similar time widespread access to significant computer power became available. Much of the original model development took place in the United States and United Kingdom, but today these models are refined and used worldwide.
HEC-RAS is simulation software used in computational fluid dynamics – specifically, to model the hydraulics of water flow through natural rivers and other channels.

The St. Lucie River is a 35-mile-long (56 km) estuary linked to a coastal river system in St. Lucie and Martin counties in the U.S. state of Florida. The St. Lucie River and St. Lucie Estuary are an "ecological jewel" of the Treasure Coast, central to the health and well-being of the surrounding communities. The river is part of the larger Indian River Lagoon system, the most diverse estuarine environment in North America with more than 4,000 plant and animal species, including manatees, oysters, dolphins, sea turtles and seahorses.
The Waterways Experiment Station (WES) in Vicksburg, Mississippi, is a United States Army Corps of Engineers research campus. The 673-acre (272 ha) campus hosts the headquarters of the Engineer Research and Development Center (ERDC) and four of its seven laboratories. Congress authorized the research complex in 1929 to develop flood control methods on the Mississippi River, as part of the Mississippi River and Tributaries Project. Subsequent research delved into topics, including coastal engineering, dredging, weapons effects, and geotechnical engineering.
UTEXAS is a slope stability analysis program written by Stephen G. Wright of the University of Texas at Austin. The program is used in the field of civil engineering to analyze levees, earth dams, natural slopes, and anywhere there is concern for mass wasting. UTEXAS finds the factor of safety for the slope and the critical failure surface. Recently the software was used to help determine the reasons behind the failure of I-walls during Hurricane Katrina.
The Barren River is a 135-mile-long (217 km) river in Southcentral Kentucky, United States, and a tributary of the Green River. The watershed of the Green River is the largest of the twelve major river watersheds in Kentucky. The Barren River rises near the Tennessee border in Monroe County and flows into the Green in northeast Warren County. The drainage basin consists of Southcentral Kentucky and north-central Tennessee.
XMDF is a library providing a standard format for the geometric data storage of river cross-sections, 2D/3D structured and unstructured meshes, geometric paths through space, and associated time data. XMDF uses HDF5 for cross-platform data storage and compression. It was initiated in Engineer Research and Development Center (ERDC) and is developed by Aquaveo . API includes interfaces for C/C++ and Fortran.
The Hydrologic Modeling System (HEC-HMS) is designed to simulate the precipitation-runoff processes of dendritic drainage basins. It is designed to be applicable in a wide range of geographic areas for solving the widest possible range of problems. This includes large river basin water supply and flood hydrology, and small urban or natural watershed runoff. Hydrographs produced by the program are used directly or in conjunction with other software for studies of water availability, urban drainage, flow forecasting, future urbanization impact, reservoir spillway design, flood damage reduction, floodplain regulation, and systems operation.
GSSHA is a two-dimensional, physically based watershed model developed by the Engineer Research and Development Center of the United States Army Corps of Engineers. It simulates surface water and groundwater hydrology, erosion and sediment transport. The GSSHA model is used for hydraulic engineering and research, and is on the Federal Emergency Management Agency (FEMA) list of hydrologic models accepted for use in the national flood insurance program for flood hydrograph estimation. Input is best prepared by the Watershed Modeling System interface, which effectively links the model with geographic information systems (GIS).
HEC-1 is software that was developed by the US Army Corps of Engineers to estimate river flows as a result of rainfall. It was written in the FORTRAN language and until 1984 could only be run on a mainframe computer.
