Note : (i) Attempt any five questions. All question carry equal marks.

(ii) Assume suitable data necessary and state them clearly.

Q.1 (a) What are the causes of failure of earthen dam and what are the design criteria?

(b) Discuss step by step the analytical procedure, adopted for analysis of stability of gravity dam?

Q.2 (a) How will you calculate the capacity of reservoir by mass inflow and mass demand curves?

(b) Describe briefly the component parts of design procedure of “Ogee Spill Way”?

Q.3 (a) Write short note on –

(i) Draft tube (ii) Surge tank

(b) Enlist various hydro power plant and describe any one in details with neat sketch?

Q.4 (a) Explain rock fill dam? And discuss soil suitable for earthen dam? (b) What is

the purpose of providing canal structure?

Q.5 (a) Explain the design details of a “Syphon Spillway”

(b) List different turbines used in hydro power station and mention their selection criteria.

Q.6 Write short note on :-

i) Galleries in gravity dam ii) Foundation treatment for gravity dams?
