Question 1
Consider the following statements concerning precipitation:
1) The Isohyetal map method of determining the average precipitation is considered to be better than the Thiessen method.
2) There is no possibility of damaging the storms because of cloud seeding activity.
3) Water that percolates through the soil emerges as the dry weather flow in streams.
Which of the above statements are correct?

Question 3
An unconfined aquifer of porosity 35%, permeability 40m/day and specific yield of 0.15 has an area of 100 km2. If the water table falls uniformly throughout the aquifer area by 0.2 m during a drought, the volume of water lost from storage is
Question 4
An unconfined aquifer of porosity 30% permeability 35m/day and specific yield of 0.20 has an area of 100 km2. If the water table falls by 0.25m during a drought, the volume of water lost from storage, in million cubic metres, is
Question 5
The rainfall on 5 successive days in a catchment was 2, 7, 8, 4 and 3 cm. if the φ-index for the storm is 3 cm/day, the direct run-off volume generated from a 195 km2 catchment is
