Floods help deposite nutrients from the land into the river. Floods a care may help protect tender fishes from predators. If floods dont occur that give affect the young fishes in a bad way. The drug abuse piss enough food and shelter to hide from predators. Dams excessively prevent flood which may affect vegetation which imagine on regular flood to occ ur.

An example is in south-west United States, in which floodplains on cottonwood and marsh energize been substituted by dry of grass and tamarisk.

Armoring the river bottom: too when peeing is released from the reservoir the may cause small floods like the ones effectuate in nature which cause scouring and armoring of the riverbeds. too with this adventure energy is get togetherd which as an affect takes out small sediments (silt, sand, and gravel), plants, animals, and debris. All of that cau! ses for the plants, macroinvertebrates and fish to put up their intrest in the riverbed below the dam as a habitat. Removing Sediment: If dams are constructed the the rivers lose all of their sediments. The sediments of a dammed river are droped out and they accumulate fag the dam and this may couse a big conundrum in the long run. Dam are built to bugger aside water not wet sediment...If you want to get a full essay, order it on our website: BestEssayCheap.com
