Floodplain restoration can also increase biodiversity by creating new or restoring degraded habitat and encourage growth of native species. [7] [8] Methods of wetland restoration in the floodplain, can help better water quality. [9] Reconnecting rivers to their floodplains promotes carbon storage in soil and regulates processes within soil. [8]
While flood control aims mainly on reducing or preventing the negative effects of floods, IFM aims on reducing the overall risk by means of land and water resources management with the goal of maximizing the benefits from the use of flood plains and minimizing the damage and loss of life due to flooding in a sustainable manner.

A floodplain or flood plain or bottomlands [1] is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge. [2] The soils usually consist of clays, silts, sands, and gravels deposited during floods. [3]
The map to the right shows a flood map for the City of York, including the floodplain for a 1 in 100-year flood (dark blue), the predicted floodplain for a 1 in 1000 year flood (light blue) and low-lying areas in need of flood defence (purple). The most sustainable way of reducing risk is to prevent further development in flood-prone areas and ...
Participation in the NFIP is based on an agreement between local communities and the federal government that states that if a community will adopt and enforce a floodplain management ordinance to reduce future flood risks to new construction in Special Flood Hazard Areas (SFHA), the federal government will make flood insurance available within the community as a financial protection against ...
The American Bottom is part of the Mississippi Flyway used by migrating birds and has the greatest concentration of bird species in Illinois. The flood plain is bounded on the east by a nearly continuous, 200- to 300-foot high, 80-mile (130 km) long bluff of limestone and dolomite, above which begins the great prairie that covers most of the ...
A river terrace is the remains of an old floodplain at a higher elevation than the present one. It typically results from river rejuvenation with further rejuvenation able to form new terraces, resulting in a step like profile around a river.
Gilbert Fowler White (November 26, 1911 – October 5, 2006) was a prominent American geographer, sometimes termed the "father of floodplain management" and the "leading environmental geographer of the 20th century" (Wescoat, 2006).
