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...

The paradox of cooling streams in a warming world:Regional climate trends do not parallel variable local trends in stream temperature in the Pacific continental United States

Creator:: Arismendi, Ivan, Johnson, Sherri L., Dunham, Jason B., Haggerty, Roy, and Hockman-Wert, David
Abstract:: Temperature is a fundamentally important driver of ecosystem processes in streams. Recent warming of terrestrial climates around the globe has motivated concern about consequent increases in stream temperature. More specifically, observed trends of increasing air temperature and declining stream flow are widely believed to result in corresponding increases in stream...

Creator:: Maxwell, Reed M., Condon, Laura E., Kollet, Stefan J., Maher, Kate, Haggerty, Roy, and Forrester, Mary Michael
Abstract:: Surface and subsurface flow dynamics govern residence time or water age until discharge, which is a key metric of storage and water availability for human use and ecosystem function. Although observations in small catchments have shown a fractal distribution of ages, residence times are difficult to directly quantify or measure...

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...

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...

Direct geoelectrical evidence of mass transfer at the laboratory scale

Creator:: Swanson, Ryan D., Singha, Kamini, Day-Lewis, Frederick D., Binley, Andrew, Keating, Kristina, and Haggerty, Roy
Abstract:: Previous field-scale experimental data and numerical modeling suggest that the dual-domain mass transfer (DDMT) of electrolytic tracers has an observable geoelectrical signature. Here we present controlled laboratory experiments confirming the electrical signature of DDMT and demonstrate the use of time-lapse electrical measurements in conjunction with concentration measurements to estimate the...

Coupled transport and reaction kinetics control the nitrate source-sink function of hyporheic zones

Creator:: Zarnetske, Jay P., Haggerty, Roy, Wondzell, Steven M., Bokil, Vrushali A., and Gonzalez-Pinzon, Ricardo
Abstract:: The fate of biologically available nitrogen (N) and carbon (C) in stream ecosystems is controlled by the coupling of physical transport and biogeochemical reaction kinetics. However, determining the relative role of physical and biogeochemical controls at different temporal and spatial scales is difficult. The hyporheic zone (HZ), where groundwater–stream water...

Quantification of metabolically active transient storage (MATS) in two reaches with contrasting transient storage and ecosystem respiration

Creator:: Argerich, Alba, Haggerty, Roy, Marti, Eugenia, Sabater, Francesc, and Zarnetske, Jay
Abstract:: Water transient storage zones are hotspots for metabolic activity in streams although the contribution of different types of transient storage zones to the whole-reach metabolic activity is difficult to quantify. In this study we present a method to measure the fraction of the transient storage that is metabolically active (MATS)...

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...

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...
