Creator:: Selker, F. and Selker, J. S.
Abstract:: Temperature anomalies can identify locations of seeps of groundwater into surface waters. However, the method’s sensitivity to details such as thermometer burial depth, sediment material, seep velocity, and surface water current are largely unknown. We report on a series of laboratory flume experiments in which controlled seeps under variable sediment...

Field evaluation of passive capillary samplers in monitoring the leaching of agrochemicals

Creator:: Brandi-Dohrn, Florian M.
Abstract:: Soil solution samplers have certain inadequacies that limit their range of possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the soil pore-water via a fiber glass wick, have shown promising results in preliminary experiments in regard to collection efficiency of water and of bromide tracers. The objectives of...

Solute and sediment transport at laboratory and field scale: Contributions of J.-Y. Parlange

Creator:: Barry, D. A., Sander, G. C., Jomaa, S., Yeghiazarian, L., Steenhuis, T. S., and Selker, J. S.
Abstract:: We explore selected aspects of J.-Y. Parlange’s contributions to hydrological transport of solutes and sediments, including both the laboratory and field scales. At the laboratory scale, he provided numerous approximations for solute transport accounting for effects of boundary conditions, linear and nonlinear reactions, and means to determine relevant parameters. Theory...

Design of interface shape for protective capillary barriers

Creator:: Selker, John
Abstract:: Sloping interfaces of fine over coarse porous material have been considered for use as barriers to infiltration for many years. Previous literature has developed analytical solutions for flow over such interfaces, numerical simulation of such flow, and the effects of anisotropy on the diversion capacity of such a system. In...

A two-color twist on test taking

Creator:: Selker, John
Abstract:: Test taking is a humiliating experience for many students, with no perceived direct educational benefit. That need not be so. When circumstances allow, I use a two-pen method of collaborative testing. Students have told me that they leave the exam having figured out what they didn’t understand, filled in the...
