Hydrogeology Studies at the Institute of Ecosystem Studies
Dr. Chowdhury's Hydrogeology course provides our students with a solid grounding in both the theory and practice of hydrogeology, including physical and chemical characteristics of streams and groundwater. The field excursions for the course give hands-on experience on hydrologic field data collection using commonly used instruments and techniques.
Groundwater flow direction and hydraulic gradient are calculated from well data using hydraulic head and the three point method. Water chemistry is determined using using field probes (pH, conductivity, DO). Streamflow measurement is found using collected flow meter data, and soil chemistry is determined using Lamotte Soil Test Kit (pH, Nitrate, Phosphate, Humus, Ammonia). The photographs here are from Dr. Chowdhury's Fall 2009 class excursion to the Groundwater Well Site at the Institute of Ecosystem Studies in Millbrook, NY.
