Flood Pulsing In Restoration : A Feasible Option for India

Abstract

Flood pulsing, which involves the restoration of natural flood conditions in wetlands has been attempted in a few places around the world, but has often been hindered by political and economic factors. Many wetlands have been destroyed by engineering projects such as dams, embankments, and channelization, and these projects often need to be reversed in order for flood pulsing to be successful. Flood pulsing is important for the survival of many plant and animal species that are adapted to or dependent on these conditions. In India, the idea of incorporating flood pulsing in riverine restoration is new, but it is worth considering for the benefit of the animals and plants that depend on these wetlands. Wetlands are also important for human use, such as for washing, bathing, drinking, livestock, and irrigation. The removal of embankments (levees or bunds) that separate the channel and floodplain can be a step towards restoration, as can the inclusion of flood pulsing in river management plans. However, these efforts must also consider the needs and potential impacts on local communities.
