Abstract: The interaction between surface and subsurface hydrology flow systems is important for water supplies. Accurate, efficient numerical models are needed to estimate the movement of water through unsaturated soil. Water infiltration from the surface to the groundwater level is usually simulated using a model based on either Richards equation or a reservoir model. In this talk we present a model derived from Darcy's law known as the Talbot-Ogden (T-O) model. Instead of one of the usual 3D models, we have a depth versus water content based on porosity domain. We report on very fast implementations.

This is joint work with Mookwon Seo, Derrick Cerwinsky, and Krishan Gahalaut.

Bio: Dr. Craig Douglas is an SER Professor of Mathematics in the Department of Mathematics. He received his Ph.D. from Yale University. His research interests include simulating contaminant transport, wildland fires, combustion, and ocean circulation using dynamic data-driven techniques. He is best known for his work in multigrid methods. He has run MGNet, a repository for information related to multigrid, multilevel, multiscale, aggregation, defect correction, and domain decomposition methods, since its inception in 1991.
