A dam is a wall of solid material built across a river. As a result water is stored in a lake that will form upstream of dam. The main purpose of the most of the dams is to create a reservoir of water to use at a later time. There are different types of dams like concrete dams, arch dams and earth dams. The design and construction of a dam depends upon its purpose and location as well as materials and workforce available.
A dam must be waterlight, and must be also stable. The dam wall must have sufficient strength to firstly bear its own weight and secondly to resist the water pressure in the lake upstream of the dam. It must have an outlet valve to release water in controlled amounts as required. It also needs a spillway so that large volumes of flood water can flow around it without causing any damage to the structure itself.
Dams are extremely useful to us for they help to control floods and supply water to dams and cities. Dams also generate hydroelectric power, and the water stored in the lake is useful for irrigation of crops. The lake that forms behind the dam can be useful for water sports and leisure activities. Often, large dams become tourist attractions of their own sight.
Dams are helpful for us because the direct where the water flows to other places that don't have water
It will harm every organism in the salt marsh ecosystem. Salt marshes provide critical habitat, food, and protection for a variety of species, including birds, fish, crabs, and insects. Destruction of salt marshes can disrupt the entire ecosystem.
The beetle with red stripes on its back plays a significant role in the ecosystem as it helps control pest populations by feeding on insects that can harm plants. This beetle also serves as a food source for other animals, contributing to the overall balance of the ecosystem.
The black beetle with orange spots plays a significant role in the ecosystem as it helps control pest populations by feeding on insects that can harm plants. This beetle also serves as a food source for other animals, contributing to the overall balance of the ecosystem.
The black beetle with yellow spots plays a significant role in the ecosystem as it helps control pest populations by feeding on insects that can harm plants. This beetle also serves as a food source for other animals, contributing to the overall balance of the ecosystem.
Oil spills can harm the ecosystem by covering marine and terrestrial habitats in oil, causing physical harm to plants and animals. The toxicity of oil can also affect the health of species, disrupting food chains and causing long-term damage to biodiversity. Cleanup efforts can further disturb the ecosystem and may not fully restore the environment to its original state.
harm
because the dams drive away the fish and makes the ecosystem FUNKY
Dams can have various negative effects on ecosystems, such as altering the natural flow of water, disrupting fish migration patterns, and reducing water quality downstream. They can also lead to habitat loss, changes in sediment flow, and impact the overall biodiversity of the ecosystem. Additionally, dams can contribute to the decline of certain species and disrupt the balance of the ecosystem.
They can harm fragile ecosystems
because they want to
yes but some organisms can harm a ecosystem
No, giraffes do not harm the Earth. No species in its proper ecosystem is harmful to the Earth as a whole. Rather, every species in its natural ecosystem helps to support the ecosystem. The only exception to that rule is humans.
I think so but im not to sure
I think so but im not to sure
Dams harm ecosystems surrounding the river.
Yes kinda, It is more commonly known as the marine ecosystem or biome and includes all large water masses. (Lakes, dams, oceans, river ect.)
yes because it harm us as well as ecosystem.
