Understanding sediment wash-off in road drainage systems under intense rainfall and high sediment masses: Insights from a large-scale modeling facility.

The main objective of this paper is to analyze, through a unique large-scale modeling facility, the RDS wash-off under various scenarios of intense rainfall and high RDS masses. A 1:1 scale physical modeling facility was used to allow precise measurement of the RDS wash-off phenomenon under two different rainfall intensities (30/50 mm/h) and three initial RDS masses (100/150/200 g/m). The accumulated and discharged masses of RDS in the different components of the modeling facility (roadway/RW, gully pot/GP and manhole/MH) were collected at the end of the wash-off simulations.

Macro-Morphological Traits of Leaves for Urban Tree Selection for Air Pollution Biomonitoring: A Review.

Urban trees provide different ecosystem benefits, such as improving air quality due to the retention of atmospheric particulate matter (PM) on their leaves. The main objective of this paper was to study, through a systematic literature review, the leaf macro-morphological traits (LMTs) most used for the selection of urban trees as air pollution biomonitors. A citation frequency index was used in scientific databases, where the importance associated with each variable was organized by quartiles (Q).

[Climatic analysis of heavy metal concentration associated with urban road-deposited sediment].

Objective To climatically assess (daily) the concentration of heavy metals (Pb and Cu) in sediment deposited on road surfaces of the localities of Kennedy and Puente Aranda (Bogota, D.C., Colombia).
