Recessional agriculture, also known as flood retreat agriculture, is a form of agricultural cultivation that takes place on a floodplain. Farmers practice recessional agriculture by successively planting in the flooded areas after the waters recede. [1] Seeds are scattered on the fertile silt deposited by the receding flood.
Spate irrigation (from the English word spate, meaning: a. a flood or inundation. b. a river flooding its banks) uses seasonal floods of rivers, streams, ponds and lakes to fill water storage basins. It is an ancient method of irrigation in arid and semi-arid climates in the Middle East, North Africa, West Asia, East Africa and parts of Latin ...
Some dams only generate power and serve no other purpose, but in many places large reservoirs are needed for flood control and/or irrigation, adding a hydroelectric portion is a common way to pay for a new reservoir. Flood control protects life/property and irrigation supports increased agriculture.
Rainfed agriculture is a type of farming that relies on rainfall for water. It provides much of the food consumed by poor communities in developing countries.E.g., rainfed agriculture accounts for more than 95% of farmed land in sub-Saharan Africa, 90% in Latin America, 75% in the Near East and North Africa, 65% in East Asia, and 60% in South Asia.
The sediment from the delta has built up to form a giant aquifer during flood season and retains water in the wetlands. The wetlands created and sustained due to built-up sediment are a habitat for numerous species of birds. [11] However, heavy sedimentation can reduce downstream river water quality and can exacerbate floods upstream.
A study from LawnStarter compared over 940 counties in the U.S. with a relatively moderate to very high flood risk according to FEMA. Here's the list.
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non ...
