Cover design

PROBLEM

The long-term performance of earth covers is a crucial component to most remediation scenarios. In particular the long-term percolation through earth covers is critical to the successful closure. The majority of covers attempt to limit the ability of air and water to enter the covered material. The performance of such covers is highly dependent on the intricate balance between precipitation and evaporation and cannot be estimated with empirical or closed-form analytical solutions.

SOLUTION

SVFlux offers climatic coupling using the Penman-Wilson formulation in order to provide an accurate account of the impact of climate on the subsurface flow regime. Solutions are available in 1D, 2D, and 3D. 1D solutions offer a quick and easy solution which may be run out for a period of 30, 50, or 100 years and result in a reasonable estimation of long-term cover performance.

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

Coupled_Salt_Water

This model demostrates the use of the software in modeling coupled water flow coupled with climate and with a salt concentration at the lower boundary. This model demonstrates the balance between precipitation moving down through the model and the salt migrating upward through diffusion.
