  ABSTRACT: Seawater intrusion is a major threat to coastal aquifers, particularly in rapidly urbanizing regions where groundwater abstraction and sea level rise interact. This study evaluates the combined influence of sea level rise and groundwater abstraction on seawater intrusion dynamics in the Tudor aquifer, Mombasa County, Kenya. Hydrochemical data, abstraction records, and spatial proximity to the coastline were analyzed using regression and correlation models to quantify relationships between chloride concentration, abstraction rates, and distance from the shoreline. Results indicate a strong positive correlation between groundwater abstraction and chloride concentration (r > 0.85), and a strong inverse relationship between distance from the coast and salinity levels (r
