IMPORTANT NOTE : I want to solve this exercise step by step described with his words by a professor of course of fundamentals of river engineering. Don`t worry, you will have a few days in a position to solve this task so important to me. ONLY SOLVE TRUE.

CHANEL DESIGN - ASSIGNMENT

EXERCISE ONE : Rigid channels: 1. Design a RIGID channel under uniform flow conditions. Consider the hydraulically efficient shape 2. Channel Sketch. 3. Determine the specific energy in the channel. Determine the critical depth and the minimum energy. 4. Determine the flow condition if: a) There is a hump (0.10m) what will be the water flow profile? b) There is a contraction of 5% 5. Determine the choking conditions

Given: o Discharge Q (m3/s) o The channel lining o The bottom slope from the map.

Half-Circular cross section; discharge 4 m3/s. The channel will be concrete finished; S0= 0.0015. EXERCISE TWO : Unlined (Erodible) channels: Design an irrigation channel using permissible velocity method. Explain all the steps.

Given: (The same as for the first case) Discharge Q m3/s Topography The soil through which the channel is to be excavated
