Effects of Stream Regulation on Channel Morphology

  • Daryl B. Simons


“The erosion cycle — detachment, transport, deposition — is described by the Second Law of Thermodynamics, which states each system tends to move in the direction of lowest energy. Because of the potential energy of soil (rock) in elevated positions and because of the kinetic energy of flowing water, all soil and water will move, eventually, to the lowest possible level, i.e., the ocean deeps, or to some temporary, intervening basin” (McHenry, 1964, 1969, 1974). The intervening basins, destined to be filled with sediment, include the reservoirs that we have become so dependent upon. We daily enjoy the benefits they provide, not fully realizing that they are continually filling and that, in the not so distant future, many will become useless. It is possible to accelerate or decelerate this process, but the filling is inevitable, given current knowledge. The reservoir’s life is dependent on sediment deposition. The under-standing of, and the ability to predict, both channel and reservoir response processes are extremely important. The rate and magnitude of changes experienced by watersheds and rivers depend on many naturally imposed factors, including floods, changes in the duration of specific flows, droughts, and changes in the water and sediment supply imposed by earthquakes, vertical changes in the earth’s crust, floods, and mass wasting.
