WebFor Questions 9 through 13, refer to Figure 7-E2 below, which shows a hill, an intermittent stream, and two index contours (darkened contour lines). Assume the contour interval for this map is 5 m, and the index contour that is crossing the stream has an elevation of 70 m. Review overview section 7.3 prior to doing this exercise. WebBased on the elevations of the contour lines that cross the stream and the general nature of the topography, state the compass direction in which you think the stream flows., Do …

WebNov 1, 2024 · Which direction do contour lines bend when they cross a stream? Contour lines “point” upstream when they cross a river or stream. Look at the Mill River in the map to the right. The V points toward the area of higher elevation. Notice how the contour lines bend uphill where the river crosses them. WebContour Lines To number contours, you must always start with a point or contour line whose elevation is known. In the following exercises, only the solid lines are contours. Number all of the contour lines with the correct elevation. * 438 Contour Interval 10' Contour Interval 20m X448 X 716 X485 Contour Interval 10' Contour Interval 20' River ... cl joias plaza niteroi

If you are making a 1:10.000 map or even a 1:5.000, you can use your phone to take points with coordinates along the river and measure its depth approximately at the center of the river or, in curves, at the exterior curve. ... WebAug 30, 2024 · To calculate the vertical exaggeration in the topographic profile shown in Figure 3.6 we divide the horizontal scale by the vertical scale: ( 1000 f t 1 i n c h) ( 100 f t i n c h) = 10. Therefore the topographic profile in Figure 3.6 represents a profile of the map surface (along the A-B line) that has been vertically exaggerated by 10 times ... cl im tv
