used for several decades. However, gypsum readily dissolves when it comes in contact with water, enriching_x000D_
the soil and groundwater but literally can create holes in the gypsum formation. With increasing size of the_x000D_

In this proposed research, the main objective is to develop a geochemical model to estimate gypsum_x000D_
dissolution rates in the RM of Alonsa. The model will be used to predict areas which are prone to sinkhole_x000D_
development utilizing three-dimensional reactive transport modeling of the shallow formations. The key to_x000D_
technology transfer is the integration of reaction kinetics into a three-dimensional transport model. This kind_x000D_
of modeling is cutting-edge technology and will allow the industry partner Stantec to expand into reactive_x000D_
