How can water diversion projects benefit developing countries?

What do diversion projects do?
Diversion programs are alternatives to initial or continued formal processing of youth in the juvenile delinquency system. Why Diversion Programs? The purpose of diversion programs is to redirect youthful offenders from the justice system through programming, supervision, and supports.
How dams and water diversion projects are used to manage freshwater resources?
Dams are used as a structure built across a river to ctrl the river’s flow. When river dammed = artificial lake or reservoir formed behind the dam, which is used for flood control, drinking water irrigation, recreation, industry, production of electrical energy (20% worlds energy by hydroelectric dams). 5.
How does a diversion dam work?
Diversion dams do not generally impound water in a reservoir; instead, the water is diverted into an artificial water course or canal, which may be used for irrigation or return to the river after passing through hydroelectric generators, flow into a different river or be itself dammed forming an onground or …
What are three advantages of dams?
- Power: Hydroelectric power is made when water passes through a dam.
- Irrigation: Dams and waterways store and provide water for irrigation so farmers can use the water for growing crops.
- Flood Control: Dams help in preventing floods.
- Drinking Water:
- Recreation:
- Transportation:
What are the positive and negative impacts of building a dam across a river?
Dam will replenish downstream ecosystems naturally. It deprives a river from the load of sediment, and seek to capture it again by corroding the river bed and banks. Deepening of riverbed lowers groundwater table that makes it inaccessible to the roots of aquatic plants.
What are the positive and negative impact on environment due to dam construction?
Greenhouse gases: The flooding of surrounding habitat around dams kills trees and other plant life that then decomposes and releases large amounts of carbon into the atmosphere. Because the river is no longer flowing freely, the water becomes stagnant and the bottom of the reservoir becomes becomes depleted of oxygen.
What are the effects of dam construction?
Dam construction could affect the biodiversity of microorganisms, benthos, plankton, fish (including aquatic mammals), botany and birds. Dam construction decreased the water fungal biomass and richness in reservoirs and downstream reaches, but increased the soil microorganisms in downstream lake wetlands.
What are the negative effects of dam construction?
Large dams have junction rectifier to the extinction of the many fish and alternative aquatic species, huge losses of forest, the disappearance of birds in floodplains, erosion of deltas, wetland, and farmland, and many other irreversible impacts.
What are the positive and negative changes in environment?
Humans affect the environment in positive and negative ways. Cutting down trees and littering have a negative effect on animals and plants. Protecting endangered species and cleaning lakes and seas has a positive effect on the environment.
How does your environment affect your personality?
