Water enters the bioretention facility at the surface of the bioretention cell. The water then infiltrates into the bioretention soil top layer. To accurately calculate that infiltration rate, the modified _____________ equation should be used.
a. Infiltration regression plot
b. Green Ampt
c. base hydrologic determinant
d. basin scale
Knowledge Checks
The critical factors in bioretention design modeling are:
a. allowed surface ponding depth
b. the bioretention engineering soil mix
c. whether or not an underdrain is included
d. the infiltration rate to the native soil
e. all of the above
Knowledge Checks
The infiltration rate determines how much bioretention facility water disappears into the ground and how much is discharged as surface flow.
a. True
b. False
Knowledge Checks
Infiltration to the native soil is recommended as long as it does not:
a. cost more than expected
b. cause problems to adjacent structures or properties
c. reach the groundwater table
d. create a habitat for non-native plants
