Question

Please solve attached problem.

In the study of rivers, a very common indicator that physical geographers measure is discharge (Q). Discharge is the amount of water that moves past a given cross-section of a river per second. The measurement in the USA is cubic feet per second The waterfall viewed in flooding has a width of approximately 16 feet across. The channel depth during flooding is approximately 8 feet deep, and the velocity is approximately 15 ft/second. What is the approximate discharge of the water as it flows down the waterfall? 1920 f2/sec 1920 ft3/sec 1920 f2/sec 0 1920 R/sec

Explanation / Answer

Width = 16ft

Depth= 8ft

Cross sectional area= Depth* Stream = 128 square feet

Discharge= Cross sectional area * the flow velocity

= 128 sq. ft * 15ft/s

= 1920 cubic feet/sec.
