Question
Chapter 22, Problem 1CR
To determine
The method used to make Portland, Oregon a more sustainable city.
Expert Solution & Answer
Answer to Problem 1CR
Portland, Oregon, had developed its urban areas more sustainable by using three scientific principles. First was improving the energy efficiencies and depending on natural energy sources for electricity and heating. Second was developing vegetation and biodiversity parks, and the third was using low polluting transport services.
Explanation of Solution
Three scientific principles of sustainability that are used to make Portland, Oregon more sustainable city are as follows:
- (i) Improving energy efficiencies and relying on solar energy, wind, and the geothermal energy for electricity, cooling, and heating.
- (ii) The urban cities also were filled with vegetation and biodiversity parks.
- (iii) The usage of low-polluting transport also helped in the development of the eco-city.
Portland has employed smart growth approaches and strong land-use policies for controlling growth, reducing reliance on automobiles, and preserving green space. Portland encourages the establishment of mixed-use neighborhoods with stores, professional offices, light industries, high-density housing, and admission to mass transit. This enabled most of the people to meet many of their everyday needs without a car Moreover, the municipal solid wastes were recycled and composted. A Climate Action Plan was implemented to reduce the emissions of carbon dioxide.

D) discontinuous permafrost
Use the attached piezometer map to make your own, clean version of the map, and indicate the elevation of the water table at all piezometer locations.
Draw equipotential lines (lines of equal water table elevation) using regular intervals – creating a contoured map of the water table.
Determine the direction of groundwater flow based on the horizontal gradient. Label the areas of recharge and discharge directly on your map.
Flow lines: Draw flow lines on your water table map. The lines should be at right angles to the equipotential lines and extend from the recharge area to the discharge area.
Hydraulic Gradient, Specific Discharge (Darcy Flux), Average Linear Velocity:
Using your water table map, estimate an average hydraulic gradient between two locations, call them locations A and B, one at the eastern-most and a second at the western-most extent of your dataset (note the north arrow on the map).
Calculate the specific discharge, q, between the two locations. For this calculation…
Calculate all the values of table 1:
Q in (L/day)
Q out (L/day)
Residence time (days)
