Lecture figures Flashcards
What does a piezometer look like and what does it do?
Piezometers measure fluid pressure
Total head in a piezometer comes from which measurements?
Point water head vs. fresh water head
Fresh water head is what the head would be if all the water was freshwater.
How does changing slope and pressure affect the way water flows?
The gradient in a homegenous, isotropic aquifer with a uniform horizontal flow field
The gradient in a homogenous isotropic aquifer with a downward component of the flow field.
Relationship of flow lines to equipotential field and gradient in an isotropic and an isotropic medium.
a- isotropic b-anisotropic
Depressed water table due to vegetation around a lake.
High water table and interlake groundwater divide
Low water table with no interlake divide (an image)
Seepage meters (an image of one)
freshwater saltwater relationship in a layered coastal aquifer
Unconfined coastal aquifer under natural ground-water discharge
Passtive saline-water encroachment due to a general lowering of the water table
Flow in the freshwater zone is still seaward.
Mechanisms of groundwater contamination
Frequency of groundwater contaminants, and frequency of sources of groundwater contaminants
Factors causing pore scale longitudial dispersion
