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...

Time scale and intensity dependency in multiplicative cascades for temporal rainfall disaggregation

Creator:: Rupp, David E., Keim, Richard F., Ossiander, Mina, Brugnach, Marcela, and Selker, John S.
Abstract:: Multiplicative random cascades (MRCs) can parsimoniously generate highly intermittent patterns similar to those in rainfall. The elemental MRC model parameter is the cascade weight, which determines how rainfall at one scale is partitioned at the next smallest scale in the cascade. While it is known that the probability density of...

Suction cup sampler bias in leaching characterization of an undisturbed field soil

Creator:: Brandi-Dohrn, Florian M., Dick, Richard P., Hess, Mario, and Selker, John S.
Abstract:: An accurate assessment of leaching losses in the vadose zone requires measurement of both solute and water flux to compute flux concentrations (C[subscript F]). Leachate collected at a depth of 1.2 m in 32 passive capillary samplers (PCAPS), which sample soil-pore water continuously at tensions of 0–50 cm H₂O was...

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 importance of hydraulic groundwater theory in catchment hydrology: The legacy of Wilfried Brutsaert and Jean-Yves Parlange

Creator:: Troch, Peter A., Berne, Alexis, Bogaart, Patrick, Harman, Ciaran, Hilberts, Arno G. J., Lyon, Steve W., Paniconi, Claudio, Pauwels, Valentijn R. N., Rupp, David E., Selker, John S., Teuling, Adriaan J., Uijlenhoet, Remko, and Verhoest, Niko E. C.
Abstract:: Based on a literature overview, this paper summarizes the impact and legacy of the contributions of Wilfried Brutsaert and Jean-Yves Parlange (Cornell University) with respect to the current state-of-the-art understanding in hydraulic groundwater theory. Forming the basis of many applications in catchment hydrology, ranging from drought flow analysis to surface...

Geography of international water conflict and cooperation: Data sets and applications

Creator:: Yoffe, Shira, Fiske, Greg, Giordano, Mark, Giordano, Meredith, Larson, Kelli, Stahl, Kerstin, and Wolf, Aaron T.
Abstract:: The Transboundary Freshwater Dispute Database provides a framework for quantitative, global-scale explorations of the relationship between freshwater resources and international cooperation and conflict. Projects were designed to test common theories linking freshwater resources to cooperation and conflict, in particular within the context of geography and environmental security. The projects, which...

Frequency distribution of water and solute transport properties derived from Pan sampler data

Creator:: Boll, Jan, Selker, John S., Shalit, Gil, and Steenhuis, Tammo S.
Abstract:: Modeling of water and solute movement requires knowledge of the nature of the spatial distribution of transport parameters. Only a few of the field experiments reported in the literature contained enough measurements to discriminate statistically between lognormal and normal distributions. To obtain statistically significant data sets, six field experiments at...

Field evaluation of passive capillary samplers for estimating groundwater recharge

Creator:: Louie, Michael J., Shelby, Patrick M., Smesrud, Jason S., Gatchell, Lance O., and Selker, John S.
Abstract:: Passive capillary samplers (PCAPS), which sample water from the vadose zone via a hanging water column in a fiberglass wick, have shown potential to provide superior estimates of soil water flux compared to alternative methods. The objectives of this study were to evaluate the performance of PCAPS under natural rain-fed...

Effects of wood on debris flow runout in small mountain watersheds

Creator:: Lancaster, Stephen T., Hayes, Shannon K., and Grant, Gordon E.
Abstract:: Debris flows have typically been viewed as two-phase mixtures of sediment and water, but in forested mountain landscapes, wood can represent a sizable fraction of total flow volume. The effects of this third phase on flow behavior are poorly understood. To evaluate whether wood can have a significant effect on...

Feasibility of soil moisture estimation using passive distributed temperature sensing

Creator:: Steele‐Dunne, S. C., Rutten, M. M., Krzeminska, D. M., Hausner, M., Tyler, S. W., Selker, J., Bogaard, T. A., and van de Giesen, N. C.
Abstract:: Through its role in the energy and water balances at the land surface, soil moisture is a key state variable in surface hydrology and land-atmosphere interactions. Point observations of soil moisture are easy to make using established methods such as time domain reflectometry and gravimetric sampling. However, monitoring large-scale variability...
