A REVIEW OF THE IMPACT OF CLIMATE CHANGE AND URBANISATION ON DRAINAGE SYSTEM IN OMAN
Main article
Abstract
The impacts of climate change have become increasingly evident, significantly altering the environment in unpredictable ways. One of the most affected infrastructures is drainage systems, which are struggling to cope with the rising frequency and intensity of extreme weather events. Rapid urbanization further exacerbates the issue, as expanding paved surfaces increase runoff, placing additional strain on drainage networks. Oman has witnessed a notable rise in extreme rainfall, resulting in frequent flash floods with severe economic, social, and environmental consequences. This paper examines the combined effects of climate change and urbanization on Oman’s drainage systems, highlighting key challenges and vulnerabilities. The findings indicate a sharp increase in catastrophic events between 2009 and 2014 compared to 2000–2008, primarily due to climate change. These events have resulted in numerous fatalities, extensive infrastructure damage, and substantial economic losses. More pavement areas and poor drainage infrastructure and inadequate management in many Omani cities further exacerbate the problem, leading to widespread flooding during extreme rainfall events. Given the rising occurrence of flash floods, it is crucial to reassess Oman’s urban development and infrastructure planning to enhance resilience against future climate challenges.
