Creator:: Arismendi, Ivan, Johnson, Sherri L., Dunham, Jason B., and Haggerty, Roy
Abstract:: 1. Temperature is a major driver of ecological processes in stream ecosystems, yet the dynamics of thermal regimes remain poorly described. Most work has focused on relatively simple descriptors that fail to capture the full range of conditions that characterise thermal regimes of streams across seasons or throughout the year....

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...

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...

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...

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...

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...
