An inflow hydrograph is routed through a reservoir to produce an outflow hydrograph. The peak flow of the inflow hydrograph is PI and the time of occurrence of the peak is tI. The peak flow of the outflow hydrograph is P0 and the time of occurrence of the peak is t0. Which one of the following statements is correct?

The outflow from the reservoir if uncontrolled will result in the peak of outflow hydrograph at the junction of inflow and outflow hydrograph.

From the given graph, it can be clearly observed that PI > Po­ and tI < to.

During rainy season, huge inflow of water takes place into a reservoir. Measures are taken to clear the reservoir while water keeps flowing into it at a constant rate. It has been observed that seven and five men can clear the reservoir in 20 and 50 days, respectively, with the initial quantity of water in the reservoir being 24 and 36 kilolitres, respectively. What is the rate of inflow of water into the reservoir in litres per day?
The water level in a municipal reservoir has been decreasing steadily during a dry spell, and there is a concern that the drought could continue for another 60 days. The local water company estimates that the consumption rate in the city is approximately 107 L/day. The state conservation service estimates that rainfall and stream drainage into the reservoir coupled with evaporation from the reservoir should yield a net water input rate of 106 exp (-t/100) L/day, where t is the time in days from the beginning of the drought, at which time the reservoir contained an estimated 109 liters of water. Integrate the balance to calculate the reservoir volume at the end of the 60 days of continued drought.

A peak flow of a flow of a flood hydrograph due to a six-hour storm is 470 m3/s. The corresponding average depth of rainfall is 8 cm.Assume an infiltration loss of 0.25 cm/hour and a constant base flow of 15 m3/s. What is the peak discharge of 6 hour unit hydrograph for this catchment?

A reservoir can be loaded up to the brim by using two cylinder tubes filling in 10 and 32 minutes respectively. Both tubes are allowed to fill reservoir together for a certain time but being choked, only 5/8 of full amount, liquid runs through the former and only 2/5 through the latter tube. The hindrance, however, being suddenly removed, the reservoir is filled in 6 minutes from that moment. How long was it before the full flow started?
An inlet pipe A originating from a river can fill a reservoir in 30 days.
