1) a) A wide channel conveys water at 8m's-'per metre (m) width of the channel. Assume the velocity distribution coefficient is unity (1.0). i) Stating any necessary assumptions, determine the specific energy for a range of flow depths between 0.5m and 4.0m. (10 marks) Plot the variation between depth of flow and specific energy for the conditions specified. (8 marks) iii) Determine the critical depth. (4 marks) iv) For the value obtained in (iii) verify that at this depth the Froude number is unity (1.0). (8 marks) b) When designing a flood relief channel to carry floodwater an engineer has a number of factors to consider. State TWO and explain the impact of each on the evaluation of the decision.
