Course Content (Syllabus)
•Works of groundwater exploitation from antiquity to the present (springs, wells, qanat, boreholes).
•Pumping tests (constant flow-Dupuit method, non-constant flow-Theis and Jacob methods), recovery test, Radius of influence.
•Characteristics of a pumped borehole (characteristic curve, critical discharge, specific drawdown, linear and nonlinear aquifer losses).
•Groundwater uses - Water needs assessment.
•Natural Recharge - Groundwater Balance - Groundwater Reserves.
•Artificial recharge of aquifers (purpose, hydrogeological conditions for the application of artificial recharge, methods, the clogging problem).
•Coastal aquifers - Seawater Intrusion - Ghyben-Herzberg Law - Measures of protection.
•Groundwater aquifers management (groundwater aquifer functions, renewable and non-renewable groundwater, over-extraction, groundwater exploitation, groundwater management).
•Types of aquifers in Greece.
•Pumping test analysis- (Steady flow)
• Pumping test analysis- (Unsteady flow- Theis method)
•Pumping test analysis- (Unsteady flow- Cooper-Jacob method)
•Radius of influence- Recovery test
•Characteristics of pumped borehole
•Coastal aquifers- Interface fresh and seawater
•Calculation of water needs
•Groundwater reserves-Groundwater balance
•Design of borehole
In the frame of the course, a one-day field trip takes place in the Axios River basin. The field trip includes pumping test of borehole with constant rate and recovery test.
