7. When just full, a reservoir has a surface area of 0.8 km², and this area is approximately constant as the water depth above this level, h, increases (where his in metres). The outflow from the reservoir is given (in m³/s) by the formula O = 90 h¹². Consider a scenario in which this reservoir is subjected to a flood with flow rates given in the table below. 0 1 2 3 4 5 Time (hours) Inflow (m/s) 0 18 22 12 6 0 a) What is the total volume of water represented by this flood? b) Carry out a flood storage routing calculation. Find the maximum water depth in the reservoir and its maximum outflow rate, and the time when this occurs.
