Near-Surface Geophysics: Imaging Groundwater Systems

Introduction to geophysical methods that can be used for imaging and characterizing groundwater systems. Recurring periods of drought and flooding in California have led state and local water agencies to search for ways to capture flood water and use it to recharge (refill) the over-pumped groundwater systems. The course this year will be structured around analyzing a new geophysical data set to identify optimal locations for recharge. The data set: 26,000 kilometers of electromagnetic data, acquired with a helicopter-deployed system, which image the groundwater systems of the Valley to a depth of ~300 m. We will analyze these data to find optimal sites for recharge by mapping out the variation in sediment type and identifying pathways for flow. Pre-requisite: CME 100 or Math 51, or co-registration in either.
