Floodplain restoration is the process of fully or partially restoring a river's floodplain to its original conditions before having been affected by the construction of levees (dikes) and the draining of wetlands and marshes.

Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
Third step: Flood Risk Management Plans: Flood Risk Management Plans are meant to indicate to policy makers, developers, and the public the nature of the risk and the measures proposed to manage these risks. However, they are not formally binding (e.g. to land-use planning). The Flood Risk Management Plans [3] are to be complete by December ...
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.
Flood management is a broad term that includes measures to control or mitigate flood waters, such as actions to prevent floods from occurring or to minimize their impacts when they do occur. [4] [5] Flood management methods can be structural or non-structural:
It is important to note that the gradually varied flow equations and associated numerical methods (including the standard step method) cannot accurately model the dynamics of a hydraulic jump. [6] See the Hydraulic jumps in rectangular channels page for more information. Below, an example problem will use conceptual models to build a surface ...
In England and Wales, the Environment Agency requires a professional Flood Risk Assessment (FRA) to be submitted alongside planning applications in areas that are known to be at risk of flooding (within flood zones 2 or 3) and/ or are greater than 1ha in area, planning permission is not usually granted until the FRA has been accepted by the Environment Agency.
