Question 3
When 3.5 million m3 of water was pumped out from an unconfined aquifer of 6.3 km2 areal extents, the water table was observed to go down by 2.5m. the specific yield of the aquifer is best approximated as
Question 4
Double mass curve are used
Question 5
The coefficient of variation of the rainfall for six rain gauge stations in catchments was found to be 29.54%. the optimum number of stations in the catchments for an admissible 10% error in the estimation of the mean rainfall will be
Question 6
