Summer Stormflow Generation In A Small Precambrian Shield Basin, Larry C. Pezzuto

Theses and Dissertations (Comprehensive)

The environmental isotope oxygen-18 and natural water chemistry were used to identify both the percent individual source component and mechanisms responsible for generating summer surface storm runoff in a small Precambrian Shield catchment. In addition, variations in radon gas (Rn-222) concentration in both surface and groundwaters were monitored in order to gain additional information not obtainable through use of the above stated tracers. Results indicate that the percent component contribution and the mechanism(s) responsible for stormflow generation within the study basin are largely dependent upon antecedent basin conditions and physical storm characteristics. Generally speaking, shortly after initiation of precipitation under …
