Question
Chapter 6, Problem 1CR
To determine
The process by which Portland, Oregon has managed to become a more sustainable city.
Expert Solution & Answer
Answer to Problem 1CR
Portland, Oregon managed to become a sustainable city after it reduced the dependence of people on automobiles, started mass transit, developed an extensive network of bike lanes and walkways, and implemented the recycling system.
Explanation of Solution
Portland, Oregon has managed to become a more sustainable city by the following ways given below:
(i) Portland used strong land-use policies to control its growth, reduce the dependence on automobiles, and preserve green space.
(ii) Portland encouraged the development of mixed-use neighborhoods with stores, light industries, professional offices, high-density housing, and access to mass transit, which allowed most people to meet most of their daily needs without using a car.
(iii) The city constructed excellent light-rail and bus lines. It further reduced car use by developing an extensive network of bike lanes and walkways.
(iv) Portland implemented the recycling system in 1987. This resulted in recycling and composting of 67% of the municipal solid waste by 2013.

Figure 9.9 is a stereogram showing a portion of the area covered by the Whitewater, Wisconsin, topographic map (Figure 9.10, page 160). Use the stereogram and the map to complete the following.
7. The streamlined, asymmetrical hills composed of till, labeled B, are what type of feature?
8. Examine the shape of the features labeled B on the map in Figure 9.10. How can these features be used to determine the direction of ice flow in a glaciated area?
9. Using the features labeled B in Figure 9.10 as a guide, draw an arrow on the map to indicate the direction of ice movement that occurred in this region.
10. What is the likely location of the outwash plain on the map? Identify and label the area "outwash plain." (Hint: Refer to Figure 9.7.)
11. Label the area covered by ground moraine.
12. What term is applied to the numerous almost circular depressions designated with the letter C?

Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day?
