Q
What is the direction of flow? Artesian? Underdrained?
A
Vertical flow is taking place
artesian = upward↑↑↑↑
underdrained = downward↓↓↓↓
7
Q
example 1
A
- capillary rise:
negative pore water pressure
Effective stress- consider both layers at boundaries
8
Q
example 2
A
- Artesian flow upward flow (pore water pressure: h=3+1)
9
Q
example 3
A
- underdrained (pore water pressure: h=1.5)
