Bank erosion is a natural process: with out river banks, rivers would not meander and change course. But, land management patterns which change the hydrograph and/or vegetation cover can act to increase or decrease channel migration rates. In many areas, whether or not the banks are unstable due to human actions, people attempt to keep a river in a single location. This can be done for environmental reclamation or to stop a river from shifting course into territory that’s being used by people. One way that this is achieved is by simply placing riprap or gabions across the bank.
Erosion controls are used in natural areas, agricultural settings or urban environments. In urban areas erosion controls are usually part of stormwater runoff management applications required by local authorities. They also involve building and keeping storm drains. On construction sites they are often implemented in combination with sediment controls such as sediment basins and silt fences.
