A Data Assimilation Enabled Model for Coupling Dual Porosity Flow with Free Flow

Coupling of dual porosity flow and free flow arises in many important applications, e.g., groundwater system and industrial filtrations. Existing Stokes-Darcy types of models cannot accurately describe this type of coupled problem since they only consider single porosity media. With the support of lab experiment data we are developing a new coupled multi-physics, multiscale model and an efficient numerical method to solve it. Furthermore, both the lab and field data provide the possibility to improve the accuracy of the model prediction through data assimilation.
