Abstract:
This thesis examines dilution gauging data from the San Pedro River east of Sierra Vista., Arizona in an attempt to quantify temporal and spatial fluctuations in groundwater baseflow to the stream. Dilution gauging measures volumetric discharge of a hydraulic system by determining the degree of dilution of a tracer solution input to the system. The basic equations of dilution gauging had to be modified to acknowledge conditions of unsteady flow and unsteady tracer flux by adding consideration of traveltime. The resulting hydrographs indicated that during wintertime conditions, the stream did not derive a great deal of its flow from the groundwater system. As the summer progressed and vegetative activity increased, the relative amount of discharge originating from the subsurface increased and the stream became more responsive to stresses from vegetative transipiration. This project was part of the Semi-Arid Surface- Land-Atmosphere (SALSA) program, a multidisciplinary effort to better understand the hydrology and ecology of semi-arid basins. This research was part of the 1997 SALSA research focus on riparian systems.
