A river reach had a flood wave pass through. At a given instant, the storage of water in the reach was estimated as 15.5 x 104 m3. Determine the storage in the reach after an interval of 3 hours if the average inflow and outflow during the time period are 14.2 m3/s and 10.6 m3/s respectively.
Water budget equation:
Inflow - outflow = change in storage
