# Groundwater

How can I measure flow through a dam or out a drain?

What does the Water Table Location sensitivity plot show?

How can I model a lined pond (account for weight of ponded water, with zero pore pressure in slope)?

Are flow quantities presented per unit length?

When using a pore pressure grid, is there a way to exclude a material?

What is the difference between a piezo line and a water table?

Is a total or effective stress method better for stability computations?

Hydraulic Boundary Conditions

Does Slide incorporate initial water content into the groundwater formulation?

Can I import a PWP grid for a low k material, and then run a slope stability analysis, instead of using the b-bar method to determine pore pressures?

How do I incorporate data from piezometers installed in the field?

B-bar analysis modeling tips

General groundwater analysis modeling tips

How can I model a well that pumps water out of a system?

How do I model aquifer storage in Slide?

How can I model an excavated boundary condition in Slide?

Why is there flow in the unsaturated zone of the model?

Is there a way to query the values of the pore water pressure on the contours?

How can I delete or move a water table boundary which exactly overlaps another boundary (e.g. a material boundary). When I try to edit the water table, both boundaries get selected.

How can I model an impermeable (zero permeability) material for a finite element groundwater seepage analysis? For example, an impermeable sheet pile wall.

## Theory

How does Slide incorporate compressibility in transient seepage analyses?

What does Slide do with pressure head?

How does pore pressure influence the results in a slope stability analysis?

What is the difference between the water table and piezometric lines?

Is the factor of safety for slope stability affected by negative pore pressures?
