Question 1
In order to ensure that no scouring takes place in the bed of a channel of bed slope 'S', constructed in an incoherent alluvium of size 'd' cm, the flow velocity should be restricted to
Question 2
A channel has an inflow of 50 cumec at time t=0, at the same time the channel has an outflow of 30cumec after certain time it was observed to have an inflow of 60 cumec with an outflow 45cumec. The change in storage depth is 20m3. The flood hydrograph with the weighing factor 0.3. Determine the storage time constant.
