Groundwater

PROBLEM

Tide fluctuations next to an ocean can create a sinusoidal wave of water which enters coastal soils. Air pressure can build up in soils as a result and the variations in water pressure can impact foundation designs close to the shore.

SOLUTION

SVFLUX can be used to model the sinusoidal movement of ocean tides and the effect on the water table. Coupled density-dependent flow of saltwater can also be accomplished when solutions are coupled with CHEMFLUX.

Please note that most of these models can be downloaded through our SVOffice product suite.


AquiferExtractionNearConstantSource

A set of 3 extraction wells are present in a 2km wide flow system. The well screens are placed in the aquifer and all 3 wells are pumped at the same rate. The drawdown cone around the wells is examined and the influence or a nearby constant water source can be seen.
