What is a SEEP W analysis?

What is a SEEP W analysis?

SEEP/W Model Analysis Summary Design Note of Seepage/Groundwater analysis. SEEP/W (SEEPage for Windows) is a finite element software product that can be used to model the movement and pore-water pressure distribution within porous materials such as soil and rock.

What is SEEP W used for?

SEEP/W supports a range of boundary condition options. Field data or user-specified functional relationships can be inputted to define hydrographs, reservoir fluctuations, rainfall cycles, vegetation effects, or land-climate interactions.

What is transient SEEPage?

Transient analysis is used when the boundary conditions inside or outside of the ground changes according to time. The main differences between transient analysis and steady state analysis are that the boundary conditions change as time passes and the fact that the transient analysis requires volumetric water content.

What is a phreatic surface?

groundwater level, phreatic surface) – The surface within the zone of saturation of an unconfined aquifer along which the pressure is atmospheric. Head, total: The sum of the elevation head, the pressure head, and the velocity head at a given point in an aquifer.

What would allow humans to access groundwater?

How do we get groundwater? Water in aquifers may be brought to the surface naturally through a spring, or can be discharged into lakes and streams. However, most groundwater is brought to the surface by pumping it through a well (which draws the water like soda through a straw) that is drilled into the aquifer.

How do you find the phreatic line?

The top flow line of a saturated soil mass below which seepage takes place, is called the Phreatic line. Hydrostatic pressure acts below the phreatic line whereas atmospheric pressure exists above the phreatic line. This line separates a saturated soil mass from an unsaturated soil mass.

What is formed when the underground water seeps to the surface?

Water that infiltrates Earth’s surface becomes groundwater, slowly seeping downward into extensive layers of porous soil and rock called aquifers. Under the pull of gravity, groundwater flows slowly and steadily through the aquifer. In low areas it emerges in springs and streams.

How is groundwater tapped?

Water in aquifers may be brought to the surface naturally through a spring, or can be discharged into lakes and streams. However, most groundwater is brought to the surface by pumping it through a well (which draws the water like soda through a straw) that is drilled into the aquifer.

What is the minimum factor of safety for slope stability?

1.25
For general slope stability analysis of permanent cuts, fills, and landslide repairs, a minimum safety factor of 1.25 should be used.
