Question

1. A hyetograph
   1. is a record of daily precipitation at a location as a function of time.
   2. records storms of varying intensity and duration.
   3. indicates precipitation intensity as well as precipitation depth during a storm.
   4. can be measured by a tipping bucket gage.

2. If the return period of a given annual precipitation at a given location is 10 years, then:
   1. the exceedance probability for that value of annual precipitation is 0.1.
   2. that value of annual precipitation will occur exactly one time every 10 years.
   3. that value of annual precipitation cannot occur twice in any 10-year period.
   4. there is a 10% chance that the precipitation in a given year will be less than or equal to that value.
3. Evapotranspiration from continental land masses:
   1. is generally equal to about 1/3 of the precipitation input.
   2. is about 80% from land and 20%from open water such as lakes and rivers.
   3. is the process by which stomata release water to the atmosphere.
   4. is the process through which the sun’s energy is introduced to drive the hydrological cycle.
