Geotechnical data on the Indus delta coastal soils

This dataset comprises geotechnical and spatial data derived from disturbed and undisturbed soil samples collected from major creeks of the Indus Delta, Pakistan. The study focuses on characterizing the physical and mechanical properties of coastal soils and assessing their spatial variability in relation to erosion susceptibility and deltaic stability. Laboratory analyses were conducted to determine key geotechnical parameters, including specific gravity, particle size distribution (using sieve and hydrometer methods to quantify sand, silt, and clay fractions), and Atterberg limits for soil consistency characterization. Soil classification was performed according to the Unified Soil Classification System (USCS). Compaction characteristics were evaluated using the Standard Proctor test to obtain maximum dry density and optimum moisture content. Shear strength parameters were determined through direct shear tests and unconfined compressive strength (UCS) testing. The dataset also incorporates spatial attributes (sampling locations and coordinates).
