Effect of Morpho-Climatic Parameters Interaction on Particle Concentration within a Canyon Street in Algiers
https://doi.org/10.35627/2219-5238/2025-33-6-65-74
Abstract
Background: Algiers, like most cities in the world, suffers from the problem of ambient air pollution. Road traffic is the main source of atmospheric pollutants and fine particulate matter (PM) in urban street canyons, endangering the health of pedestrians. This phenomenon also depends on factors relating to site-specific conditions and morpho-climatic variables.
Objective and methods: Our study aims to assess the correlation between the concentration PM and morpho-climatic parameters in two streets, located in the 19th-20th century urban fabric specific to the city, using in-situ measurements during the summer season and statistical methods.
Results: The findings showed that canyon geometry and trees were the main factors affecting PM concentration in urban street canyons, compared to temperature, which acted as a secondary parameter.
Conclusion: This study could serve as a guide for future urban planning by taking into account the morphological, microclimatic and roughness parameters of urban canyons when designing future urban projects in order to improve local air quality and protect human health.
