Abstract

This paper presents a novel method for assessing hyporbeic water quality dynamics using advances in sensor technology. High-resolution (15 min) dissolved oxygen (DO) and hydraulic head data were combined to assess groundwater-surface water (GW-SW) interactions in the hyporheic zone. DO concentrations varied at fine temporal and spatial scales, depending on the relative contributions of GW and SW. The effect of sample frequency on observed patterns of variability was assessed with reference to studies of the ecology of salmon spawning habitat. Conventional approaches fail to capture the full range of temporal variability in hyporheic water quality and demonstrate the need to reassess the interpretations of previous studies of the hyporheic zone.
