The data observed at station C were doubtful because of some topographical changes there. Verify whether the data observed at C is consistent and correct it, if necessary.

Ques 3) Following figure shows a typical layout of a catchment area ABCDF, Six rain gauge stations are  established at A, B, C, D, E and F.The precipitation observed at these six stations in july 2004 is as follows:

Find the average precipitation over the catchment during July 2004 by Thiessen’s polygon method.

Ques 4) For a drainage basin of 600 km2, isohyetals drawn for a storm gave the following data:
Isohyetals  interval (cm)
15--12

Estimate the average depth of precipitation over the catchment.

Ques 5) Estimate the constant rate of withdrawal from a 1375 ha reservoir in a month of 30 days during which the reservoir level dropped by 0.75 m in spite of an average inflow into the reservoir of 0.5  million m3 per day. During the month the average seepage loss from the reservoir was 2.5 cm, total precipitation on the reservoir was 18.5 cm and the total evaporation was 9.5 cm.

Ques 6) A catchment has four sub-areas. The annual precipitation and evaporation from each of the sub-areas are given below. Assume that there is no change in the groundwater storage on an annual average (i) precipitation, and (ii) evaporation. What are the annual runoff coefficients for the sub-areas and for the total catchment taken as a whole?
