Earth dams are generally built of locally available materials in their natural state with a minimum of processing. Homogeneous earth dams are built whenever only one type of material is economically available. The material must be sufficiently impervious to provide an adequate water barrier and slopes must be relatively flat to make it safe against piping and sloughing.

Piles are installed by a special pile driving device known as a pile hammer. The hammer may be suspended from the boom of a crawler crane, supported on a large frame called a pile driver or carried on a barge for construction in water.

It is usually the flow in an Open Channels Surface Flow: The flow which is above the ground level is called surface flow. Ground Flow: The flow which is below the surface of the earth is called ground flow. Open channel flow is not completely enclosed by boundaries, unlike pipe flow. Open channel is always under the action of gravity, while pipe can be under gravity

Cement can be defined as the bonding material having cohesive & adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly. Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in

Open channel can be said to be as the deep hollow surface having usually the top surface open to atmosphere. Open channel flow can be said to be as the flow of fluid (water) over the deep hollow surface (channel) with the cover of atmosphere on the top. Examples of open channels flow are river, streams, flumes, sewers, ditches and lakes etc. we can be said to be as
