Lessons 5: How Does the Contour of the Land Affect Runoff?
Contour refers to changes in elevation of the land in a given area. Topographic maps present land contours through the use of various elevation lines. How do you think contour impacts the runoff of transported pollutants in a watershed?
Doing the science
- Study Figure 1 below, which is a portion of an island in Rhode Island. Each contour line represents an elevation change of 10 meters.
- Determine the elevation above sea level of the following locations: Oliphant, Aquidneck Centre, Wyatt, Green End, and Paradise. Record your results in Table 1 below.
