Aquifer Identification in Basement Complex and Sedimentary Environments focuses on the methods and principles used to locate and characterize groundwater-bearing formations within two major geological settings: basement complex terrains and sedimentary basins. It examines how aquifers in basement complex areas are typically found in weathered or fractured rocks, while those in sedimentary environments occur in porous and permeable layers such as sand, gravel, or limestone. The topic highlights the use of geological, geophysical, and hydrological techniques to distinguish between these environments, evaluate groundwater potential, and ensure efficient water resource development. Course objectives include enabling learners to understand the characteristics of aquifers in both basement and sedimentary settings, identify suitable exploration and evaluation methods, analyze factors influencing groundwater occurrence, and develop skills for effective aquifer mapping and sustainable groundwater management.
Exploring the Application of Geophysical Principles to Subsurface Groundwater Investigation, Hydrological Concepts, Aquifer Identification, and Field Procedures focuses on the use of geophysical methods and hydrological principles to study and assess groundwater resources beneath the earth’s surface. It examines techniques such as electrical resistivity, seismic surveys, and magnetic methods used to detect and map subsurface water-bearing formations, alongside key hydrological concepts like groundwater flow, recharge, and storage. The topic also highlights the processes of identifying different types of aquifers and conducting field procedures for data collection, analysis, and interpretation to support sustainable water resource management. Course objectives include enabling learners to understand the basic geophysical principles used in groundwater exploration, analyze hydrological processes related to subsurface water, identify and classify aquifer systems, and develop practical skills in applying field methods for groundwater investigation and evaluation.
