Pengembangan Sistem Drainase Berkelanjutan untuk Mengatasi Banjir Perkotaan

Abstract

Urban flooding has become a major challenge due to rapid urbanization, climate change, and inefficient water management systems. Conventional drainage systems, which primarily focus on channeling rainwater away as quickly as possible, often fail to accommodate extreme precipitation, leading to severe inundation and environmental degradation. This study explores the integration of natural drainage systems and ecological engineering in urban design to enhance rainwater absorption and mitigate flood risks. By implementing bioretention zones, permeable pavements, and infiltration systems, this approach significantly reduces surface runoff by 46% and increases groundwater recharge by 30%, as demonstrated through hydrological simulations and case studies. The findings indicate that nature-based drainage solutions are not only effective in controlling urban floods but also contribute to long-term water conservation and ecological sustainability. Furthermore, the study highlights the importance of policy interventions, urban planning strategies, and community engagement in ensuring the widespread adoption of sustainable drainage systems. Future research should focus on optimizing design configurations across diverse urban landscapes and integrating real-time monitoring technologies to enhance adaptive water management in flood-prone areas
