Introduction: role of groundwater in the hydrologic cycle, problems and
perspectives. Occurrence and movement of groundwater: origin, age,
distribution, hydrogeology of aquifers, Darcy's law, flow characteristics,
general flow equations, unsaturated flow. Groundwater and Well
Hydraulics: steady and unsteady radial flows in aquifers (confined,
unconfined and leaky), multiple well systems, partially penetrating wells,
characteristic well losses, specific capacity. Surface and Subsurface
investigations of Groundwater: Geologic methods, remote sensing,
geophysical exploration, electrical resistivity and seismic refraction,
gravity and magnetic methodsÍž test drilling, various logging techniques
including geophysical and resistivity methods. Water wells: methods of construction, completion and development, yield tests, protection and
rehabilitation of wells. Quality of groundwater: measures of quality,
groundwater samples, physical, chemical and biological analyses, water
quality criteria, and salinity. Pollution of groundwater: sources and
causes, distribution, attenuation, evaluation and monitoring, remediation.
Management of Groundwater: concepts of basin management,
groundwater basin investigations, conjunctive use, mathematical
modelling, examples, artificial recharge of groundwater: concepts,
recharge methods, recharge mounds, induced recharge. Saline water
intrusion in aquifers: occurrence , shape and structure of the interface ,
upconing, control of saline water intrusion.
