Groundwater spatial variability within an atoll island: assessing shallow aquifer heterogeneity with geophysical and physicochemical measurements

This study examines the spatial variability of shallow groundwater on Dhigelaabadhoo Island using Electromagnetic Induction surveys, groundwater monitoring, and sediment analyses. The research reveals how variations in island morphology—such as differences in elevation, reef flat width, and sediment composition—affect the spatial distribution of groundwater lenses and the overall aquifer dynamics. Dataset description: the dataset consists of five zip files. Each contains raw data for each sensor used in the study and a readme.txt file describing the data.
