I understand how to do #1. the answer is 500 when converting meters to kilometers. I am not sure how to do #2. Please I need help.
1. A stream starts out 2000 meters above sea level and travels 250 kilometers to the ocean. What is the average gradient in meters per kilometer?
2 Suppose that the stream mentioned in question 3 developed extensive meanders so that its course was lengthened to 500 kilometers. Calculate its new gradient. How does meandering affect gradient?
formula
discharge (m3/second)= channel width (meters)
X channel depth (meters)
X velocity (meters/second)
