Water Resources

ARC’s water resources research is established to address key issues in hydrology at local and regional scales, primarily through the development and implementation of state-of-the-art integrated, data assimilating hydrological/transport models. The aim is to create hydrological models that are scalable to the regional, national and global extents which serve as effective tools for water resources management and monitoring.


Research Areas and Capabilities

Tracer groundwater movement

Tracer groundwater movement

ARC’s goal is to develop best available data and water balance products using numerical methods and data collection. The water resources research group works closely with research associates, faculties, and students worldwide. Current research focuses on United State Department of Energy sites and involves development of numerical tools to simulate past, present, and future hydrological scenarios in local and regional scales. In addition, ARC’s expertise in sampling and monitoring water quality provides a practical training ground for undergraduate and graduate students at FIU. ARC’s water resources research interests also extend to national and global-scale model development, hydrologic information systems, remote sensing, and data assimilation. Students working with ARC water resources research group benefit from exposure to multiple disciplines, giving them a broad foundation for understanding complex environmental issues.

Research Areas

  • integrated surface and groundwater modeling
  • water quality modeling
  • contaminant fate and transport modeling
  • land and water resources management
  • climate change analysis
  • storm water modeling


ARC water resources research is focused broadly on developing numerical tools that can be used to monitor, assess, and evaluate water quality and hydrological changes in the environment using various commercial and non-commercial hydrology software that are approved by federal and state agencies. Our areas of expertise include:
