Analytical solution and simplified analysis of coupled parent-daughter steady-state transport with multirate mass transfer

Creator:: Haggerty, Roy
Abstract:: In this technical note, a steady-state analytical solution of concentrations of a parent solute reacting to a daughter solute, both of which are undergoing transport and multirate mass transfer, is presented. Although the governing equations are complicated, the resulting solution can be expressed in simple terms. A function of the...

An efficient method to estimate processing rates in streams

Creator:: Gonz alez-Pinz on, Ricardo and Haggerty, Roy
Abstract:: We provide an efficient method to estimate processing rates through simple algebraic relationships derived from the transient storage model equations. The method is based on the transport equations, but eliminates the need to calibrate highly uncertain (and intermediate) parameters. We demonstrate that under some common stream transport conditions dispersion does...

Quantifying spatial differences in metabolism in headwater streams

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, and Argerich, Alba
Abstract:: Stream functioning includes simultaneous interaction among solute transport, nutrient processing, and metabolism. Metabolism is measured with methods that have limited spatial representativeness and are highly uncertain. These problems restrict development of methods for up-scaling biological processes that mediate nutrient processing. We used the resazurin–resorufin (Raz-Rru) tracer system to estimate metabolism...

Development of a “smart” tracer for the assessment of microbiological activity and sediment-water interaction in natural waters: The resazurin-resorufin system

Creator:: Haggerty, Roy, Argerich, Alba, and Marti, Eugenia
Abstract:: A “smart” tracer is a tracer that provides, directly or through measurement of its concentration or in combination with another compound, at least one “bit” more of information about the environment through which it travels than a conservative tracer. In this study we propose and present the chemical compound resazurin...

Diurnal timing of warmer air under climate change affects magnitude, timing and duration of stream temperature change

Creator:: Diabat, Mousa, Haggerty, Roy, and Wondzell, Steven M.
Abstract:: Stream temperature will be subject to changes because of atmospheric warming in the future. We investigated the effects of the diurnal timing of air temperature changes – daytime warming versus nighttime warming – on stream temperature. Using the physically based model, Heat Source, we performed a sensitivity analysis of summer...

A mean residence time relationship for lateral cavities in gravel-bed rivers and streams: Incorporating streambed roughness and cavity shape

Creator:: Jackson, Tracie R., Haggerty, Roy, Apte, Sourabh V., and O’Connor, Ben L.
Abstract:: Accurate estimates of mass-exchange parameters in transient storage zones are needed to better understand and quantify solute transport and dispersion in riverine systems. Currently, the predictive mean residence time relies on an empirical entrainment coefficient with a range in variance due to the absence of hydraulic and geomorphic quantities driving...

Effect of multiple lateral cavities on stream solute transport under non-Fickian conditions and at the Fickian asymptote

Creator:: Jackson, Tracie R., Apte, Sourabh V., and Haggerty, Roy
Abstract:: In field studies of solute transport, transient storage within lateral cavities and other stream features generates breakthrough curves (BTCs) with pronounced and persistent skewness. Current solute transport theory requires that the coefficient of skewness (CSK) decrease over time because the system eventually reaches Fickian conditions. However, published data show that...

Scaling and predicting solute transport processes in streams

Creator:: Gonz alez-Pinz on, Ricardo, Haggerty, Roy, and Dentz, Marco
Abstract:: We investigated scaling of conservative solute transport using temporal moment analysis of 98 tracer experiments (384 breakthrough curves) conducted in 44 streams located on five continents. The experiments span 7 orders of magnitude in discharge (10⁻ ³ to 10³ m³/s), span 5 orders of magnitude in longitudinal scale (10¹ to...

Measuring aerobic respiration in stream ecosystems using the resazurin-resorufin system

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, and Myrold, David D.
Abstract:: The use of smart tracers to study hydrologic systems is becoming more widespread. Smart tracers are compounds that irreversibly react in the presence of a process or condition under investigation. Resazurin (Raz) is a smart tracer that undergoes an irreversible reduction to resorufin (Rru) in the presence of cellular metabolic...

Defining and measuring the mean residence time of lateral surface transient storage zones in small streams

Creator:: Jackson, Tracie R., Haggerty, Roy, Apte, Sourabh V., Coleman, Anthony, and Drost, Kevin J.
Abstract:: Surface transient storage (STS) has functional significance in stream ecosystems because it increases solute interaction with sediments. After volume, mean residence time is the most important metric of STS, but it is unclear how this can be measured accurately or related to other timescales and field-measureable parameters. We studied mean...
