Question

QUESTION1 a) channel is 10.0m2/s (Q = 100m3/s/m). The channel consists ng bed slope, Sol =0.0001 (for ABC), and S02 = 0.008 for (CDE), eates to control the flow and the flow depth at the vena Specific discharge of a wide rectangular channel is 10.0m7s( . The channel consists of two long reaches having the following bed slope, Son -0 (Q 10.0m2/s/m (see Figure 1) respectively. There are two gates to con contractor after each gate is approximately 0.3m. Take the Manning's coefficient s approximately 0.3m. Take the Manning's coefficient as 0.015 sketch and name the water surface g location using the profiles along the channel. Indicate flow depth at each flow changin Tabulate, flow d plot specific energy variation along the channel (not to scale). Note: it is requi notations (dni, dn2, de, dup, ddown, di, d2 etc.) 2. epths at flow changing locations. If energy loss due to the gate is negligible, red either to tabulate or indicate energy values on the graph. b) Sketch a typical hydrological cycle and name the main processes/storages Draw a Hydrograph and a Hyetograph (name the axes of each plot) The mean annual rainfall measured at Stations A, B, C and D are 80mm, 120mm, 100mm espectively (see Figure 2 catchment ns A, B, C and D are 80mm, 120mm, 100mm and 70mm ). Construct Theissen polygon and estimate mean annual rainfall of this

Explanation / Answer

CONCLUSION:-

a)

1) MILD SLOPE

2)STEEP SLOPE

ALL CALCULATIONS REGARDING THIS SHOWN IN THE ABOVE IMAGES

b) FIGURES AND PROCESS ARE WRITTEN IN THE ABOVE IMAGES

c)

PRESECENTAGE INCREASE IN 20 YEAR =65%

ITS CALCULATIONS ARE SHOWN IN THE ABOVE IMAGES

d)

QP IS CALCULATE ABOVE IN THE IMAGE

RUNOFF=QP*TIM

=11.2*30*60

=20160 m3

Phi INDEX= (P-Q)/T

=20160/(1.4*104*30*60)

=.8 mm/sec.
