Burge formula  cumecs is based upon

For the estimate of high floods in fan-shaped catchment, the formula used is

For calculating the evaporation rate over a reservoir surface E = 0.771 (1.465 - 0.00732 B) (0.44 - 0.007375 V) (pe - pa), the equation is given by

Consumptive use of a crop during growth, is the amount of

The efficiency of a pump may be taken as

Shrouding is provided in

A well penetrates to 30 m below the static water table. After 24 hours of pumping at 31.40 litres/minute, the water level in a test well at a distance of 80 m is lowered by 0.5 m and in a well 20 m away water is lowered by 1.0 m. The transmissibility of the auifer, is

In the derivation of Thiem's formula  the following assumption is not applicable
