Exam Questions for Binford Lecture 23: Florida Water Resources

1. The Earth is 71% ocean, which is salt water. It seems that removing the salt from ocean water (desalination) would be an excellent way of providing enough freshwater for everybody. What is the most important reason that desalination is not widely used?

    a. Not everybody lives near the coast and transporting water inland to users would be very expensive.
    b. Desalination requires very large energy use to remove salt from water, and is therefore much more expensive than other sources of water.
    c. Desalinized water is still contaminated with toxins and bacteria making it unsafe for human consumption.
    d. The effluent from desalination plants is extremely salty and pollutes the rivers and oceans into which it is dumped.
    e. Desalination is impossible with today's technology.

2. The drainage basins of the rivers of Florida extend into Alabama and Georgia, but not beyond. The consequence of this spatial patterns is that

    a. water quality of river water in Florida is directly dependent on the geology, soils, vegetation, and human activity in every state in the southeastern part of the United States.
    b. management of surface water resources in Florida can be done without regard to any land area outside the state.
    c. there is no connection between the different areas of the state with regards to surface water resources.
    d. farmers and orange growers around Orlando should be concerned with water management decisions made by people in Alabama or Georgia.
    e. None of these answers is a consequence of the spatial distribution of the drainage basins of Florida rivers.

3. In the United States, the largest component of outflows in the water budget is

    a. actual evapotranspiration.
    b. consumptive use.
    c. runoff to the ocean.
    d. instream uses.
    e. groundwater recharge.

4. A stream's flow rate is called its

    a. water flow.
    b. runoff.
    c. discharge.
    d. rate of flow.
    e. flow velocity.

5. Which of the following is an example of the consumptive use of water?

    a. water which evaporates from an irrigated field.
    b. hydroelectric power production.
    c. using water for a bath.
    d. river navigation.
    e. all of these are consumptive use.

6. Runoff, in a hydrological and water resources sense, is:

    a. all water that leaves a drainage basin via surface flows.
    b. the water that flows across the surface as sheet flow.
    c. precipitation that hits solid rock or other impermeable surfaces and flows to nearby streams and lakes.
    d. the overland flow that fills up retention ponds.
    e. a term that is not used in water resources.

7. Which section of the state of Florida has a long-term average water budget deficit (defined as precipitation < potential evapotranspiration)?

    a. The entire state runs a water budget deficit, and depends on inputs from Alabama and Georgia.
    b. The extreme southeast of the state: Miami - Palm Beach area.
    c. The panhandle has a deficit.
    d. The central ridge.
    e. No place is the state has a deficit.

8. A map of potential evapotranspiration in Florida shows a general increasing trend from ________, which is caused mostly by ______.

    a. north to south; increasing level of insolation.
    b. west to east; increasing amount of rainfall.
    c. south to north; increasing amount of aquifer recharge.
    d. east to west; decreasing influence of the Atlantic Ocean.
    e. there is no trend of potential Et; the entire state is under the influence of the maritime tropical air masses.

9. The seasonality (difference between seasons) of rainfall is greatest in which section of the state of Florida?

    a. south
    b. central
    c. panhandle
    d. northeast
    e. around Tallahassee

10. Florida has two areas of very high precipitation. What causes this pattern?

    a. Summer convective thunderstorms drop rainfall all over the state but especially in the southeastern section, while winter cold fronts bring large amounts of moisture to the panhandle.
    b. Summer warm fronts bring large amounts of moisture to the southeastern part of the state while winter convective thunderstorms drop rainfall all over the state, especially in the southeastern section.
    c. Summer convective thunderstorms prevent rainfall in the central part of the state while water that evaporates from the Atlantic Ocean and the Gulf of Mexico is precipitated in the southeastern part of the state and the panhandle.
    d. Hurricanes and tropical storms disproportionally hit the panhandle and southeastern region of the state resulting in higher average annual rainfall.
    e. None of these answers is correct.

11.  The "normal" precipitation and temperature reported by the Weather Channel and the newspaper weather reports is based on

    a. averages of measurements made during the 20th century.
    b. the long-term results of climate models that predict "expected" precipitation and temperature.
    c. averages of measurements made during rolling 30-year periods, e.g. 1931-1960 and 1961-1990.
    d. a constant determined from the standard measurements made at one weather station in each state over the past 10 years.
    e. consensus values determined by an expert committee of the National Weather Service.

12. What states are currently experiencing "severe" or  "extreme" drought conditions (at least as of October 20)? You will have to look this up; try "U.S. drought monitor" in a Google search.
   
    a. Massachusetts, New Hampshire, Rhode Island, Connecticut, Vermont, Maine.
    b. Iowa, Florida, Michigan, South Carolina, New Hampshire
    c. Georgia, South Carolina, North Carolina, Tennesee, Kentucky, and parts of Texas.
    d. California, Texas, Arizona, Wisconsin.
    e. Arizona, Nevada, Utah, Wyoming, Montana

13. Evapotranspiration (ET) varies _________ from year to year because the major factor that influences ET is _________, which also is nearly constant from year to year..

    a. widely, windspeed
    b. widely, precipitation
    c. minimally, precipitation
    d. minimally, insolation
    e. widely, insolation

    a. variation in potential evapotranspiration
    b. variation in vegetation
    c. variation in land use
