Common Types of Infiltration Systems

Each type has distinct failure mechanisms that climate stresses can increbate. For example, extended drough can cause soil craccing in bioretention media, leading to preferential flow pathways that bypass treatment, while intensie rainfall can wash out fine sediment that clogs the surface of permeable pavements.

Climate Groźby to Infiltration System Longevity

Climate change directly impacts infiltration infrastructure through gh five primary mechanisms: changes in precipitation intensity, prolonged dught, increaged freeze- thaw cycles, rising sea levels in coasural zone, and shifting temperatur thatt affect vegetation and microbial activity.
