Question

A Trou Ran Drainage Basin I, Cornplete parts ? through h in F. A '1.2. TOPOGRAPHIC MAP REVIEW FOR DRAINAGE BASIN MAPPING a. This map is contoured in feet. The contour interval is: ft b. The elevation of point X is: c. The elevation of point B is: d. The elevation of point A is: e. The distance from A to B is f. The gradient from A to B is: g. Lightly shade or color the area ft ft ft mi(s) ft/mi inside each closed contour that represents a hilltop, then draw a dashed line to indicate the drainage divide that surrounds Trout Run drainage basin. h, Trout Run flows (drains down hill) in what direction? 1 mile Figure A11.2.1 2. Imagine that heavy rain fell on a saturated landscape at location X in Fig. A11.2.1. Is it likely that runoff water would flow from X downhill into Trout Run? Explain your reasoning. Figure A11.2.2is a portion of the Lake Scott 7.5-minute quadrangle, Kansas, that is centered around latitude 38.7'N longitude 100.95 W. This area is an ancient upland surface that slopes gently eastward from an elevation of about 5500 feet along the Rocky Mountains to about 2000 feet above sea level in western Kansas. Streams in western Kansas drain eastward and cut channels into the ancient upland surface. Small tributary streams merge to form larger streams that eventually flow into the Mississippi River

Explanation / Answer

Answers: a. 20 ft b. 240 ft c. 100 ft d. 180 ft e. 1.15 miles. explanation: 15mm= 1mile in scale. Measuring A to B in map, distance is 13mm. Therefore, the real distance is 1mile x (15/13) = 1.15 miles. f. 69.56 Explanation: graident = vertical difference / horizaontal distance = 180-100 / 1.15 = 69.56 ft/miles
