  11. Derive an expression for principle stresses and shear stresses at the toe and
  heel of an Gravity dam
  12. What do you understand by the elementary profile of a Gravity dam? Derive the expression for determining base width based on stress criteria.
  13. A concrete Gravity dam has following details
  i)Maximum water level = 305m
  ii)Bed level = 225 m
  iii) Level at top of dam = 309 m
  iv)The D/S slope starts with reduce level of 300 m with slope 1V:0.75H
  v)The uplift pressure 100 % at the heel and 50% at gallery and 0 %at the toe.
  vi)The density of concrete is 24 KN/m3
  vi) Top width of dam = 8 m
  Check the stability of dam and calculate principle and shear stresses
  14. Compare “Gravity Dam” with “Earth Dam”
  15. Explain the measures for embankment seepage control and foundation seepage control in an Earth Dam.
  16. Explain with the help of neat sketch , the various component parts ,along with their functions, of diversion head work.
  17. What are the different types of spillways ?Explain the design criteria of an Ogee spillway in brief.
  18. Adischarge of 1750 cumec has to passed over an ogee spillway with co efficient of discharge of 2.25 at a head of 3.8m .What should be the effective length of spillway? Neglect velocity of approach.
  19. Define energy dissipation . Discuss various methods used for the energy dissipation downstream of spillways.
  20. Write short notes on
  i)Silt Excluder

  Great work CP. 👍
  
  I hope we get same collections for all branches in engineering.

  Great work! Now can we also have answers to above questions in separate threads? It will attract many engineers to CE.

  It is the ratio of the average discharge to the maximum discharge (design discharge).
  Mathematically, Capacity factor=Average Discharge/Design Discharge
  For example, a canal was designed or the maximum discharge of 50 cumecs, but the averagedischarge is 40 cumecs, then the capacity factor is
  40/50=0.8
