Visualizing Saline Intrusion in a Three-Dimensional, Heterogeneous, Coastal Aquifer

Abstract

We visualize remediation scenarios for a coastal aquifer in Oman, where the natural fresh-saltwater interface is negatively affected by groundwater pumping for irrigation. The 3D aquifer is characterized by strong heterogeneities ranging from local to regional scale, which impose visual challenges in the interpretation of large data amounts. This paper addresses the visualization workflow, which helped to ensure correct model setup and successful calibration of a transient model run. The modelling and visualization exercise identified sensitive areas for salinization along the coast and assessed the impact of remediation measures on the groundwater reservoir in space and time. Proper visualization helped to interpret and illustrate the complex results adequately, and to transfer scientific information to stakeholders.
