where L MGAM is the infiltration depth calculated
based on the MGAM model.
The hydraulic model parameters and infiltration depth values are listed
in Table 3.
[Insert Table 3]
The average relative error was 10.41%, which indicates that the
modified MGAM model effectively reflects the water infiltration depth of
the loess area at different times within the bioretention facilities.
The water infiltration depth of the facility increased as the initial
water content at the site increased. The infiltration depth of water in
the facility decreased as the saturated water content of the site
increased. To prevent any adverse impact caused by the bioretention
facilities to the loess foundation, compaction and other foundation
treatment methods can be used to adjust the saturated water content at
the site so as to control the influence range of rainwater infiltration.
