Riprap causes morphological changes in the riverbeds they surround. One such change is the reduction of sediment settlement in the river channel, which can lead to scouring of the river bed as well as coarser sediment particles.
The Uranium Mill Tailings Remedial Action (UMTRA) Project was created by the United States Department of Energy (DOE) to monitor the cleanup of uranium mill tailings, a by-product of the uranium concentration process that poses risks to the public health and environment. The Uranium Mill Tailings Radiation Control Act passed by Congress in 1978 ...
The Hanford Site occupies 586 square miles (1,518 km 2) – roughly equivalent to half the total area of Rhode Island – within Benton County, Washington. [1] [2] It is a desert environment receiving less than ten inches (250 mm) of annual precipitation, covered mostly by shrub-steppe vegetation.
The tailings and other contaminated material are being buried near Crescent Junction, Utah, northeast of the junction of Interstate 70 and U.S. Route 191, about 30 miles from the tailing pile. [13] Excavation occurs in phases, two of which are complete as of July 2014. Each phase is about 45 acres (18 ha) and is excavated to about 25 feet (7.6 m).

The Great Man-Made River Project (GMRP) was conceived in the late 1960s and work on the project began in 1984. The project's construction was divided into five phases. The first phase required 85 million m³ of excavation and was inaugurated on 28 August 1991. The second phase (dubbed First water to Tripoli) was inaugurated on 1 September 1996.
Rip Raps was originally built in 1817 as part of the harbor defenses to provide a setting on the south side of the navigation channel for Fort Wool (built originally in 1830 and named Fort Calhoun but renamed during the Civil War and rebuilt in 1902), the companion to Fort Monroe (on the northern side of the channel) in protecting access to Hampton Roads with an anti-submarine net.
