This document outlines the course units for two engineering courses: Ground Water Development and Management, and Pavement Analysis and Design.
The Ground Water course covers topics like the hydrologic cycle, aquifer types, groundwater flow, pumping test analysis, subsurface exploration techniques, artificial groundwater recharge, saline water intrusion, and groundwater basin management.
The Pavement Analysis and Design course covers flexible and rigid pavement stresses and designs, materials testing, construction methods, maintenance needs, and strengthening of existing pavements. It examines factors like loads, material properties, and failures.
