waterfalls are temporary features of rivers because stream erosion is greatest at waterfalls and rapids. The water that falls at the base of the waterfall erodes rock there, leaving the rock at the tops of the waterfalls to overhang. Overall, undermining causes waterfalls to recede farther upstream.

A confined aquifer has a specific storage of 2.4 x 10-S ft and a thickness of 300 ft. How much water (in acre-ft) would it yield

Georgia [21]

Answer:

water it yield is 244290.45 ft

Explanation:

given data

specific storage SS = 2.4 × $10^{-5}$ ft

thickness b = 300 ft

water declined ΔH = 4.8 ft

radius r = 1,500 ft

to find out

How much water would it yield

solution

we know that

volume of water is

Vw = S × Area × ΔH ..............1

here S = specific storage × thickness

S = 2.4 × $10^{-5}$ × 300

S = 7.2 × $10^{-3}$

and

area = πr² = π 1,500² = 7068589.471 ft²

volume of water is

Vw = 7.2 × $10^{-3}$ × 7068589.471 × 4.8

Vw = 244290.45

so water it yield is 244290.45 ft
