What else can I help you with?
The lowest level to which a stream can erode its channel?
The base level is the lowest point to which a stream can erode its channel. This can be the level of the body of water into which the stream flows, such as a lake or ocean, or an artificial structure like a dam. At base level, erosion stops and sediment deposition begins.
What is the name of the large artificial lake that was create by the Aswan high dam project?
Lake Nasser
Did the aswan dam create lake nasser?
Yes. The dam holds back water that would normally flow down the river, leading to water accumulating behind the dam: an artificial lake.
What artificial land form is created when a dam is built?
The dam retaining wall is an artificial land form.
What are the world's artificial largest waterfalls?
The spillway of the Grand Coulee Dam is the HIGHEST, artificial waterfall in the world. The crest of the dam is 550 feet above the lowest bedrock.
Why the base of the dam is made wider?
The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
Why are the walls of dam thickened near the base?
why are the walls of a dam thickened near the base
What is an artificial lake that holds water usually by a dam?
Resevoir
How can you make an artificial lake?
depends on the size, if its in a natural depression , install a dam, if its on level land dig a hole, and cover the bottom with clay, or dig down to bedrock,
What is a dam How is it useful to us?
A dam is used to make an artificial lake in a river which can be used to generate hydroelectric power or as a reservoir.
Can a river create a dam?
no it can not
Why do dams have a very broad base?
Dams must hold back water of a certain depth, determined by the height of the dam. The pressure exerted by this water on the dam is dependent in part by its depth, since the base of the dam must be able to hold pressures exerted by the weight of all the water above the base. Since the pressure is greater at the base, the dam is broader at the base.
