Prof. Bayani Cardenas (CV)
I study the broad topic of flow and transport dynamics of natural hydrologic systems. Primarily trained as a hydrogeologist, I earned all my degrees are from Earth science departments. The scales of my investigations span across grain to global – from the interstitial space of a few grains of sand to the entire globe. Our research group uses a variety of approaches including conventional hydrologic and water quality monitoring, geophysical surveying, remote-sensing, laboratory and field experiments, and mathematical modeling including high-performance computational models and novel theories. I am particularly motivated by problems that cross disciplinary boundaries which require drawing ideas and approaches from different fields.

Near surface geological processes are mostly attributed to physical and chemical changes in the environment, and often pay little to no attention to the crucial part played by microorganisms. My interest is studying geochemical, physical and biological aspects involved in the nutrient cycle at the groundwater / surface water interaction boundary called the hyporheic zone.  The implications resulting from a more profound understanding of processes involved in the nutrient cycle in this zone could lead us towards improvements in management of various fresh water reservoirs.

With increasing concerns on global climate change, there has been a growing interest in the potential impacts of it to groundwater reservoirs along with the surface waters. My principal research interest is based on the interaction between these major reservoirs in regional and local scales with the emphasis on water balance, saltwater intrusion, and climate variability. Use of field observations, space driven data and coupled simulation models are the tools required to understand the major mechanisms and make projections for the future states of these resources.
