Hydrogeophysics is the interdisciplinary field at the intersection of hydrologic processes and geophysical measurements. For most groundwater problems, data on saturated and unsaturated zone processes and properties is limited to shallow soil pits,  point sensors, and sparse wells. The main goal of hydrogeophysics is to contribute additional data related to hydrologic system states and dynamics by leveraging geophysical imaging that may be sensitive to properties such as saturation, porosity, and infiltration rate. Examples of measurement methods that may be applied include ground penetrating radar, electrical resistivity, seismic refraction, and nuclear magnetic resonance.  This talk will cover a basic introduction to hydrogeophysical measurements, coupling geophysical data with flow models, rock physics transforms to extract hydrologic properties, observing dynamic processes with time lapse measurements, and related application examples.
