It is made up of impervious material and its object is to make the dam water tight. The particle size of material used in the core is small so that it can retain water and do not allow its further seepage.

Each of the 24 satellites emits signals to receivers that determine their location or range by computing the difference between the time that a signal is sent and the time it is received.

Dam should be feasible to construct e.g availability of labor, material, experienced and skilled personnel etc.

Shear wall is a structural member used to resist lateral forces i.e parallel to the plane of the wall. For slender walls where the bending deformation is more Shear wall resists the loads due to Cantilever Action and for short walls where the shear deformation is more it resists the loads due to Truss Action. These walls are more important in seismically active zones because

A slump test is a method used to determine the consistency of concrete. The consistency, or stiffness, indicates how much water has been used in the mix. The stiffness of the concrete mix should be matched to the requirements for the finished product quality. Slump is a measurement of concrete's workability, or fluidity. It's an indirect measurement of concrete
