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-structural type. Structural methods hold back floodwaters physically, while non-structural methods do not.
From the ecological perspective, the most distinctive aspect of floodplains is the flood pulse associated with annual floods, and so the floodplain ecosystem is defined as the part of the river valley that is regularly flooded and dried. [19] Floods bring in detrital material rich in nutrients and release nutrients from dry soil as it is flooded.
The essential goal of the concept was to further assess and explain the various communities in the system. Vannote himself described the current situation as follows, "in those days, most people studied a square meter of water to death [22] ”. Meaning that previous research was always only on small pieces of water and only rarely was the ...
Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel. [1] The term "at flood stage" is commonly used to describe the point at which this occurs.
The flow of water through the planet’s nearly 3 million rivers is changing rapidly, with potentially drastic implications for everything from drinking water supplies to flood risks, according to ...
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 ...
Flooding could impact food security for more than 5.6 million people across multiple African nations, a new study has found. While these impacts are usually negative, the researchers also ...
It is completely surrounded by flood water and protected only by earth dykes. There is some food aid, but many in the area survive by foraging for water lily roots and fish to supplement their ...
