Gas Transfer at Weirs Using the Hydrocarbon Gas Tracer Methid With Headspace Analysis

Research output: Book/ReportOther report

Abstract

Gas transfer at hydraulic structures is an important source or sink of dissolved gas in a river system, even though the water is in contact with the structure for a short period of time. The primary reason is that bubbles are entrained into the flow, greatly increasing the surface area available for transfer. Thus, the same gas transfer that might require several miles of stream can occur at a waterfall or hydraulic structure, such as an overflow weir or a spillway [Thene and Gulliver, 1988].
