1) The discharges in a river at three points 100 m apart in the downstream direction are 65, 71 and 80 m3/s. If the depth of flow at the central point is 5 m and the width of the river is 100 m, using only the Continuity equation estimate the depth of flow in 5 minutes time.

2) A stream conveying a flood peak of 50 m3/s (velocity 1.25 m/s and depth 1 m) is divided into 1 km long reaches for solution of the unsteady equations. Determine the largest value of ?t for which the solution will be stable.

3) A channel 0.5 m deep is constructed in material with its threshold of motion defined by a shear stress of 12 N/m2. Determine the maximum allowable bed slope for this channel.
