5. Draw the sketch of the following cross section of channel and indicate the specified dimensions. a Semi-circular section with radius r = 3.0m b) Rectangular section : b=4.0m, and d = 2.0m C Trapezoidal section : Bottom width b = 3.0m Depth : Side Slope : 2 horizontal to 1 vertical d = 2.0m i. Calculate the area (A), wetted perimeter (P)and the hydraulic radius (R) of each channel. ii. If the discharge of these three channels are equal to 6.0m/s, determine the velocity of water flowing of each channel and identify which channel has the highest value of velocity 2, the lowest value of velocity ?

please solve for h and explain...thanks!

Question 2. Below shown is the profile for a road construction at a station. This is a fill section. Sometimes the letter C is used to designate cut and F to indicate fill for the vertical distance or depth. In other words, a point below the base would have a negative sign in a fill section. F 11.8 below corresponds to -11.8 ft. The baseline is 50ft. Calculate the area for the fill section. (Answer: 137.3 yd²) 50ft F 11.8 -42.5 F 14.3 -32.0 0 -25 25 olo F 15.8 25 25 Baseline F 16.3 65.4
