Factors Influencing River Life
A river's speed determines which species of plants and animals can live in it. Normally, the faster the river flows, the more oxygen it contains. But fast-flowing water is more difficult for some species to swim in.
A river may pass over several types of rock. Each rock type influences both water and species of animals and plants it can support. For example, the freshwater crayfish needs lots of oxygen and lime to build up its thick outer skeleton, a fast flowing river going over chalk is ideal. Man also influences river life . Some rivers are used by large industrial boats and have to be dredged deeply to maintain a deep channel, preventing natural development of the river bottom. Smaller boats require the removal of water plants, reducing habitat for wildlife. The wash from fast motor boats erodes the riverbanks, flooding nests and washing away wildlife.
Finally, population has great effect on river life. The most common types: sewage, chemicals and other waste from industry, oil, pesticides, litter, detergents, large amounts of hot water, animal waste and dense or decaying plant growth.
