$ii. a. Look at the terrain and elevation trends along the length of the river. Which part of the river crosses the steepest terrain? Which part crosses the gentlest terrain? iii. IDO b. Look at the shape of the river. How does the shape of the river channel and its valley change along its length? stelbs of inslavlupa el buong gein en oloma les) 0001 anoesigen gem 1691 to hdmun orth easte sisos ledsov A al boassiqxo ed nao 11 qsm c. Calculate the gradient of the river over the entire length as well as between points 1 and 2, points 2 and 3, and points 3 and 4. Look at your numbers for the river's gradient. Where does the river have the steepest gradient? Where is its gradient gentlest? f. When the vertical and horizontal scales are not the same, a profile is said to have a vertical exaggeration. To calculate vertical exaggeration, divide the vertical fractional scale by the horizontal fractional scale: i. Now draw a longitudinal profile on a separate sheet of paper (blank or graph paper). A longitudinal profile allows you to visualize the changing gradient along a river's length. A longitudinal profile is a graph of a river's elevation versus its length, and the slope of the profile is related to the segment gradient you calculated in the previous section of the lab. The vertical scale is 1 inch = 600 ft. This equals 1 inch = 1200 fractional scale is therefore 1/ 1200 (same number as above). The horizontal scale is 1 inch = 30,000 ft. This equals 1 inch = 360,000 inches. The fractional scale is therefore 1/360,000 (same number as above). Vertical exaggeration = V scale/H scale = =-0.02 inches. The 59$
