Hydrogeology QUIZ

Practical problems solved by hydrogeology

• Analyse rock stability

• Evaluate groundwater reserves

• Determine mineral resources

• Utilise mineral and thermal groundwaters

Groundwater flow

• Groundwater flows through sediment and rock porosity

• Clay is water permeable

• Gravel has high porosity

Aquifer is a geological water-bearing environment completely or partially saturated with free groundwater

• True

• Not true

• Partly true

Groundwater recharge

• Decreases groundwater levels and water reserves.

• It is a process of infiltration of surface water into the aquifer

• Naturally occurs when water is injected through wells

Groundwater discharge

• Wells are cylindrical, vertically drilled tapping structures, used to tap drinking, mineral and thermal groundwaters

• Gravitational springs are with deep groundwater circulation and small regime changes

• Artesian springs are with shallow groundwater circulation, and strongly depend on rain infiltration
