1.A 5-m wide rectangular channel is carrying a flow of 5 cubic meter per second. If the Manning n=0.013 and the bottom slope, So=0.0001, determine the normal depth using a converging iteration. Use conveyance method to verify your result.
2.The depth of flow in a long canal with a trapezoidal across section is 2 meters. The discharge is 15 cubic meters per second with a bottom width=10m and side slopes of 1V:2H. If the discharge is increased to 20 cubic meters per second determine the new depth of flow?
