خلاصه	Hydrogeological survey is the systematic characterization of groundwater systems, including aquifer geometry, water quality, flow paths, and recharge-discharge dynamics. Rooted in Darcy's law (1856) and quantified by Theis (1935), this method is essential for water resource management, contaminant remediation, and hazard assessment. Modern surveys integrate geology, geophysics, geochemistry, and numerical modeling to understand complex subsurface flow systems.	Geologic mapping is the systematic observation and documentation of rock types, structures, and relationships exposed on the land surface. Pioneered by William Smith in 1799, this foundational field method remains essential for understanding subsurface geology, economic geology, hazard assessment, and paleoenvironmental reconstruction. Modern mapping integrates field observations with satellite imagery, digital logs, and GIS technology to create comprehensive three-dimensional geological frameworks.	Well log analysis is the systematic examination of measurements recorded by instruments lowered into a borehole to characterize subsurface lithology, fluid content, and petrophysical properties. Originating in the 1940s, this method has become indispensable for petroleum exploration, groundwater assessment, and engineering geology. Well logs provide direct depth-correlated data that anchor interpretation of seismic surveys and constrain reservoir models.
