Abstract: As climate change intensifies the hydrological cycle, coastal regions are increasingly vulnerable to extreme events such as rising temperatures, altered precipitation patterns, and sea level rise (SLR). Over the past 140 years, sea levels have risen by approximately 0.2 meters, with projections indicating an additional rise of 0.3 to 1 meter by 2100. This rise also affects groundwater levels, reducing soil infiltration capacity and increasing surface runoff. Additionally, the increase in impervious surfaces in urban areas further exacerbates surface runoff. Therefore, it is crucial to analyze the combined impact of these factors on surface runoff in coastal areas. This study aims to investigate the complex interactions between climate change, SLR, groundwater dynamics, and land use change on surface runoff in coastal regions, and to quantify the contribution of each factor to runoff increases. The findings will inform urban resilience planning, addressing the multifaceted impacts of climate change on coastal hydrology.
