Professional Interests

Dr. Pohll’s major research interest is in numerical simulation of hydrologic systems. Evaluation of complex hydrologic systems requires tools from the traditionally fragmented fields of surface water hydrology, groundwater hydrogeology, and statistics. He is specifically interested in the development and application of numerical models that allow the end users to better understand the system and to make decisions within an uncertain environment. He uses state-of-the-art numerical tools to evaluate the all of the uncertainties inherent in the modeling environment so the end users understand how to quantify the worth of the modeling results in relation to the ramifications of the decision.
