Abstract: The analysis focuses on a steady‐state budget model. To simplify the analysis, the mechanisms of decay and diffusive sediment feedback are ignored. These omissions result in a lower‐bound representation of the net loss ...

Abstract: The “approximate delta method” is a simple procedure for simultaneous calculation of the stream reaeration coefficient, primary production rate, and respiration rate from a single-station stream diurnal profile of dissolved ...

Abstract: A simple approach, the delta method, is derived to estimate stream reaeration, primary production, and respiration rates on the basis of diurnal dissolved oxygen measurements. The method uses three features of the diurnal ...

Abstract: The Streeter-Phelps dissolved oxygen model is modified to incorporate storage zones. A dimensionless number reflecting enhanced decomposition caused by the increased residence time of the biochemical oxygen demand in the ...

Abstract: The concentrations of dissolved oxygen and chlorophyll have declined in the Seneca River, New York since 1991 as a result of zebra mussel respiration and filtering. Recently measured data were used to approximate flux rates ...

Abstract: Conservative and gaseous tracers are used in conjunction with several models to characterize transport and gas transfer for a small, sluggish lowland stream, the Piako River, in New Zealand. Results obtained with the ...

Abstract: The hydraulic habitat preference of the nuisance benthic alga Cladophora glomerata was investigated in a shallow river using an unmanned aerial vehicle (UAV) and acoustic Doppler current profiler (ADCP). Three separate ...

Abstract: The development and application of a one-dimensional heat transport model in highly transient streams governed by unsteady flow is described here. The resultant framework consists of two modules called the hydrodynamic and ...
