1.	The area of a sloping surface of a protective embankment of mean height d, side slopes S: 1 and length L is _________(a) d x d x s(b) (d2 x (ds)2)1/2(c) L.D (1 + s2)1/2(d) 2 L.D (1 + s2)1/2This question was addressed to me in my homework.Question is from Accounts topic in section P.W.D of Civil Engineering Drawing
Answer» Correct option is (c) L.D (1 + s2)1/2 Explanation: An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic MOUND of various compositions of soil, sand, clay, or ROCK. It has a semi-pervious waterproof NATURAL COVERING for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles BINDS the particles together into a stable mass rather than by the use of a cementing substance.
