Lecture 46: Groundwater Exploration 8

This lecture expands the previous discussion by focusing on the impact of structural features like faults and folds on groundwater distribution. It explains that faults create secondary permeability and can act as hydrologic boundaries or conduits for groundwater flow, with their presence often indicated by springs, seepages, or displacement in rock layers. The lecture also covers how folds, such as synclines and anticlines, complicate aquifer distribution, making detailed subsurface information necessary for accurate predictions. Additionally, it discusses unconformities as critical features that mark erosional surfaces and affect the continuity of aquifers, often influencing the productivity of groundwater resources. Understanding these structural elements is essential for effective groundwater exploration and management.
