• During July, 1996 monthly inflow to Tarbela Reservoir was 20 billion cubic meters and outflow was 18.70 billion cubic meters. Find the rate of change of storage and change in storage during the period. o At Basha Reservoir the storage volume is 11,410 million cubic meters at elevation of 1,180 m. If inflow is 11,500 cubic meters per second. Find the time to fill the reservoir up to mentioned elevation. Assume that losses are negligible.
