Optimizing runoff and pollution mitigation through strategic low-impact development (LID) integration in the Bouznika city development plan

Abstract

This study evaluates the effectiveness of Bouznika's (Morocco) urban development plan in mitigating stormwater runoff and pollution. The plan incorporates Low Impact Development (LID) strategies like green roofs, permeable pavements, and rain gardens. Utilizing the Storm Water Management Model (SWMM), the research simulates their impact on runoff volume and pollutant reduction for various scenarios, both individually and combined. The results highlight that combining multiple LIDs achieves substantial pollutant reduction, with green roofs emerging as the most effective single solution. This research seeks to incorporate effective water management techniques by embracing LID practices as part of a sustainable urban development plan.
