Answer 2

Answer:

Dams are classed as (i) storage dams (ii) diversion dams (iii) detention dams, depending on the usage of the reservoir created by the dam.

Explanation:

Storage dams:

• This dam is constructed mainly to impound the excess river water on its upstream side during floods.
• The stored water is used when the river runs with a deficient supply.
• These are used to store water.

Diversion Dam:

• The purpose of this dam is not to store excess water behind it but to raise the level of water so that water may be diverted into a system of canals.
• The height of this dam is, therefore, relatively small as no reservoir is to be formed to store water.

Detention dams:

• This dam was built to keep floodwaters under control.
• During floods, the flood water is kept behind the dam.
• When the floodwaters recede, the water is gradually released at a safe rate.

Hence, there are three types of dams namely storage dams, diversion dams, and detention dams.
