Abstract

The increase in flooding events in major cities has driven the search for new strategies that incorporate Low Impact Development (LID) units into urban drainage. This research analyzes the performance of infiltration trenches to determine flow and infiltration physical parameters in different soil types in the Federal District of Brazil (FDB), comparing urban area and preserved Cerrado biome. The results show that most soils in the Federal District of Brazil have good infiltration conditions, particularly the Red Latosol and Red-Yellow Latosol. Infiltration trenches were effective in storing significant volumes of water, especially during initial runoff events where favorable soil moisture conditions exist. The Regolithic Neosol exhibited low infiltrability, making its use for infiltration trenches not recommended.

Keywords: cerrado, infiltration trench, red latosol.
