If the trend in total water withdrawal represented in the graph continues, which of the following is most likely to happen in the future?

Most countries will switch to desalination as a source of freshwater.

Use of groundwater resources will replace surface water resource use.

Aquifers will be depleted if demand is higher than recharge rate.

An increased reliance on groundwater resources to meet demand will cause the water table to rise in regions worldwide.

This type of irrigation is often used by small-scale farming operations, and it requires extensive labor to set up individual irrigation lines.

Drip irrigation

Flood irrigation

Spray irrigation

Furrow irrigation

Fish landings are defined as the total catch of marine fish that are brought into ports for sale. Bycatch refers to the unwanted fish and other marine organisms that are caught during commercial fishing operations, but are not harvested or sold. Which of the following methods would you use to calculate the percent of the total catch of all fish in 2012 that was bycatch?

Rapid runoff following a heavy rainfall may cause flooding downstream from urban areas. Which urban design strategy will most likely slow water runoff though an urban area and decrease the risk of downstream flooding?

Preserve open areas with intact vegetation

Add large drainage pipes near parking lots

Use large flat roofs in new construction

Widen concrete streets and sidewalks

Based on the diagrams above, which of the following best explains how urban runoff could be decreased?

Decrease the number of trees in urban areas to increase ground infiltration.

Increase the number of trees to decrease the amount of evapotranspiration.

Replace more porous pavement with traditional pavement to decrease the amount of evapotranspiration.

Replace traditional pavement with more porous pavement to increase ground infiltration.
