Flow Nets Flashcards
1
Q
Explain flow nets
A
A graphical way to represent 2-dimensional ground water flow
2
Q
What do you assume for net construction
A
- Homogeneous and isotropic
2. Steady state
3
Q
Explain equipotential lines
A
Connect points if equal head together in a single aquifer
4
Q
What do flow lines show?
A
Path of groundwater flow through aquifer
5
Q
3 types of boundary conditions
A
1) impermeable boundaries
2. Constant head
3. Water table boundary
6
Q
Explain impermeable boundaries
What are they based on?
A
No flow boundaries
Geology -> shale granite
Planes of symmetry
7
Q
Explain constant head boundaries
A
Same as equipotential lines
8
Q
What equation explained water table boundaries
A
h = z +y

11
Q
Two types of subsystems for groundwater flow
A
Local or regional flow systems
