Compute the change in water storage of surface water system of university of Goroka which precipitation of 2000mm, evaporation of 50cm, and transportation of half of the rate of evaporation. Neglect ground water flow in the stream and surface water flows into was flow in to system is equivalent to the following from the system. Assume that the soil in the areais saturated all throughout.

Answer 1

To compute the change in water storage in the surface water system of the University of Goroka, we need to consider the precipitation, evaporation, and transportation rates.

Given:
Precipitation = 2000 mm
Evaporation = 50 cm
Transportation = (1/2) * Evaporation

First, we need to convert the precipitation and evaporation values to the same unit of measurement. Since the transportation rate is already in centimeters, we will convert mm to cm.

1 mm = 0.1 cm

Therefore,
Precipitation = 2000 mm * 0.1 cm/mm = 200 cm

Now, we can calculate the change in water storage using the formula:

Change in Water Storage = Precipitation – Evaporation – Transportation

Change in Water Storage = 200 cm – 50 cm – (1/2)*50 cm
Change in Water Storage = 200 cm – 50 cm – 25 cm
Change in Water Storage = 125 cm

Therefore, the change in water storage of the surface water system of the University of Goroka is 125 cm.
