Question 3
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.

The area between the two isohyetes 45 cm and 55 cm is 
, and that between 55 cm and 65 is

, and that between 55 cm and 65 is . What is the average depth of annual precipitation over the basin of ? Question 5
A Catchment of area 250ha received rainfall of 10.5 cm in 120min due to a storm. At the outlet of the catchment, the runoff lasted for about 15hr with an average discharge of 2.20 cumec/sec. what is the amount of water which was not available for runoff due to the combined effect of infiltration, evaporation and transpiration? (in m3 )
Question 6
The rainfall on six successive days on a catchment was 6.5, 2.35, 4, 9.8, 7.2 and 2.67 cm. If the ∮- index value for the storm can be assumed to be 3.78 cm/day. The total direct runoff (mm)from catchment is
