Abstract:
Climate change has intensified rainfall in Pakistan, necessitating innovative stormwater
management strategies. This thesis explores the potential of PCPs. They can sustainably reduce
surface runoff and boost groundwater recharge in urban areas. The study uses a mixed-method
approach. It integrates field experiments and computer simulations. They assess various factors
that affect PCP performance. We evaluate the effectiveness of PCPs in reducing runoff volume
and peak flow rates.
Findings reveal that PCPs significantly reduce surface runoff and delay peak discharge. It thereby
mitigates flood risks. Also, PCPs help recharge groundwater. They add to environmental
sustainability and urban resilience against stormwater challenges. PCPs emerge as a viable and
eco-friendly alternative for stormwater management. They offer benefits such as runoff reduction
and groundwater recharge. This addresses the dual challenges of urbanization and climate change.
Future research should focus on long-term performance and evaluation of PCPs. It should
establish broad guidelines for wider use.
