Stormwater Exam 1 Questions With
Verified Solutions
Precipitation is any product of the condensation of atmospheric water vapor that falls
under the gravitational pull from the clouds. (T/F) CORRECT ANSWERS True
What are forms of precipitation CORRECT ANSWERS rain, snow, sleet, hail, drizzle
What is the one main difference between drizzle and rain CORRECT ANSWERS
Droplet size. Rain droplets are larger than drizzle droplets.
Which process moves the moisture upward in the water cycle CORRECT ANSWERS
Transpiration
What are the measurements of rainfall CORRECT ANSWERS intensity, depth, duration
A plot that illustrates the variability of rainfall depth over time is called a hydrograph
(T/F) CORRECT ANSWERS False. A Hyetograph illustrates it
How do we determine a random event CORRECT ANSWERS
What is used to determine the exceedance probability of an event and get the
cumulative distribution function for a set of samples CORRECT ANSWERS Plotting
position formulas
What is the basis for choosing a theoretical probability distribution CORRECT
ANSWERS Goodness-of-fit to the samples
IDF curves are developed based on CORRECT ANSWERS Historic Rainfall Data
For a given return period, the average intensity decreases as the duration increases
(T/F) CORRECT ANSWERS True
