The ordinates of rainfall mass curve of a storm over a basin of area 850 km2 measured in mm at 1 hour intervals are 0, 10, 22, 30, 39, 45.5, 50, 55.5, 60, 64 and 68. If the infiltration during this storm can be represented by horton’s equation with fo=6.5 mm/hr, fc=1.5 mm/hr and k=0.15 /hr. Estimate the resulting runoff volume.

The flow hydrograph ordinates observed in a basin with a
precipitation area of 500 km2 for a
3-hour showers are given in the table below. Assuming the base flow
is constant and 10
m3/h;
a) Calculate the total volume of flow as m3, which consists of
precipitation.
b) Calculate excess rainfall height and duration.
c) Determine the unit hydrograph which is equal to the
precipitation period of excess
rainfall.

A tidal power plant of single-basin type, has a basin area of
(24+n1000) km2. The tide has
a range of 10 m. The turbine stops when the head on it falls below
3m. Calcualte the average power generated during one
filling/emptying proces in MW. Assume the turbine-generator
efficiency is 70% and the time taken as 22350 seconds. Take sea
water density = 1025 kg/m3. n=57

If the pH of a 2.54-cm rainfall over 3700 km2 is 3.20, how many
kilograms of sulfuric acid, H2SO4, are present, assuming that it is
the only acid contributing to the pH? For sulfuric acid, Ka1 is
very large and Ka2 is 0.012.
