Building the dam :

Concrete dams will need a large quantity of ready concrete, so, a concrete batching plant is often built on site. Concrete is then transferred to the dam either using a system of convey or belts or using trucks and cranes. The traditional method of placing the concrete is to pour it into a formwork mould made in the required shape of the dam. The dam is built upwards 1-2 m at a time, and the concrete left to cure before the next section is formed on top.

Strip Irrigation Method :

In strip irrigation method, fields are divided into strips of different size. A boundary called ‘Med’ is formed to separate the strips. These strips are constructed according to the slope. The source of water is situated at the highest place in the field from where the whole field can get the flow of water. The width of strips is decided as per quantity of water. More wastage of water is caused if strips are wider. Length of strip is decided by the slope of land and its structure. Effect of soil composition is also visible on it.
