To provide an overview of groundwater interaction with solid Earth materials. During the first ¾ of the lecture sequence, fundamental mass balance and flow equations are derived from first principles, then applied to practical groundwater problems. Geologic maps and cross sections are used extensively in quantifying the flow of water through porous ground and the effects of pumping from aquifers. The last ¼ of the lecture sequence concentrates on aquifer yield and groundwater exploration in various geologic terrains. Laboratory exercises focus on quantitative interpretation of hydrogeologic and hydrochemical data. The field exercises relate surface flow variations in perennial mountain streams to spring discharge and groundwater flow in associated aquifers.
Lecture Meets MWF 11:00-11:50 PM, Building 8, Room 239
Laboratory Scheduled for Friday 8:00-10:50 AM. Laboratory will typically meet in Room A-634. Two Saturday field trips will be taken to San Antonio Canyon to carry out surface water and groundwater observations. Tentative dates (rain or shine) are January 7 and February 4. Laboratory work will usually be due one week after date of assignment. A substantial penalty will be assessed for late submissions.
