Chapter 9 Stormwater Management
Correct 100%
What is the worst case scenario result of stormwater runoff? (Page 217) - ANSWERThe worst case for
stormwater runoff would be pollution and loss of life.
What is a dry well? (Page 230) - ANSWERA dry well is an underground structure that disposes
unwanted water such stormwater by recharging an aquifer.
What is meant by the term: flow attenuation? (Page 230) - ANSWERWhat is meant by the term flow
attenuation is prolonging the flow time of runoff to reduce the peak discharge.
What is the best case scenario of stormwater runoff? (Page 217) - ANSWERThe best case of
stormwater runoff is that it helps prevent flooding.
What is a flood plain? (Page 236) - ANSWERan area of low-lying ground adjacent to a river, formed
mainly of river sediments and subject to flooding.
Discuss Best Management Practices as it applies to stormwater. (Page 229) - ANSWERBest
Management Practices that applies to stormwater is anything that prevents stormwater runoff such
as procedures, protocols, structural devices, or site design.
List two stormwater preventative measures. (Page 229) - ANSWERTwo stormwater preventative
measures would include debris removal from streets, vegetated swales, and pervious soil buffers.
List two stormwater control measures. (Page 243) - ANSWERTwo stormwater control measures
would be source controls and treatment controls.
How does the development of land create more stormwater runoff? (Page 224) - ANSWERThe
development of land create more stormwater runoff by water running off faster and the time of
concentration of watershed decreases because the runoff flows faster to the outlet over modified
land surfaces
