To identify alternative approaches to fill this critical data gap and properly parameterize the model, they evaluate the importance of surface water groundwater interactions, determine whether explicit coupling of watershed and groundwater models is warranted, and assess limitations in simulating human-aquifer interactions.

To extend the model to account for other factors that may affect water transport in soil, such as soil heterogeneity and preferential flow. To apply the model to different environmental contexts, such as calculating crop yields and monitoring flood risk. To develop strategies to deal with the increasing impact of climate change using the model.
