Sebastián Vázquez-Gasty is the lead author of a new paper in Groundwater titled “Implementation and Evaluation of Fully 3D Richards’ Equation in MODFLOW 6,” alongside GSI’s Sorab Panday, Christian Langevin of S.S. Papadopulos & Associates, and Tirthankar Roy of the University of Nebraska-Lincoln.
The paper introduces a fully three-dimensional Richards’ equation solver integrated into MODFLOW 6, enabling researchers and groundwater professionals to more accurately simulate water movement through saturated and unsaturated soils, including capillary effects and lateral moisture flow.
Using three benchmark tests against established groundwater modeling software, the researchers demonstrated strong agreement in simulated moisture and pressure responses, along with computational efficiency and numerical stability. This advancement offers new capabilities for studying groundwater recharge, vadose-zone processes, and complex subsurface flow conditions.
Congratulations to Sebastián and his co-authors on this publication and their contributions to advancing groundwater modeling capabilities!
