This model verifies the SVAirFlow formulation against the Unconfined Layer example presented by Baehr & Hult in the paper Evaluation of Unsaturated Zone Air Permeability Through Pnuematic Tests (1991).
Dewatering of the region around a well enclosed by sheet piling.
Transient simulation of dewatering of the region around a well enclosed by sheet piling.
Illustrates the pumping of wells around an excavation.
The purpose of this numerical model is to illustrate the use of the SVFLUX software in well-pumping calculations.
A simple water extraction well is modeled to compare the SVFlux Well Object feature to to a well modeled with geometry.
Simple plan view example. Used in modeling concepts section of User's Manual. Flow from an injection well can be seen to flow preferentially through a region where the soil has a higher hydraulic conductivity.
The pumped well single model file is designed to illustrate the use of SVFLUX in applying a pumping to a well in a 2D model. Model setup time = 9 minutes.
This model demonstrates the use of 3 pumping wells in a basic 3D model
Saturated material and steady-state. The purpose of this numerical model is to determine the pumping rates required to dewater a 1000 m deep well with a radius of 0.5 m in a theoretical material. It is assumed that groundwater is allowed to seep into the well at all depths. The water table in the well is drawn down almost instantly and maintained at an elevation of 0 m. The resulting radial change to the surrounding water table is examined.
