    Instruments for distributed fiber-optic measurement of temperature are now available with temperature resolution of 0.01°C and spatial resolution of 1 m with temporal resolution of fractions of a minute along standard fi ...
  • Selker, John; van de Giesen, Nick; Westhoff, Martijn; Luxemburg, Wim; Parlange, Marc B. (American Geophysical Union, 2006-12-19)
    A new approach to monitoring surface waters using distributed fiber optic temperature sensing is presented, allowing resolutions of temperature of 0.01°C every meter along a fiber optic cable of up to 10,000 m in length. ...
  • Ochiai, Naoyuki; Kraft, Erika L.; Selker, John S. (American Geophysical Union, 2006-12-20)
    Prediction of colloid transport in the subsurface is relevant to researchers in a variety of fields such as contaminant transport, wastewater treatment, and bioremediation. Investigations have traditionally relied on col ...
  • Assouline, S.; Selker, J. S.; Parlange, J.-Y. (American Geophysical Union., 2007-03-16)
    The prediction of the time to ponding following commencement of rainfall is fundamental to hydrologic prediction of flood, erosion, and infiltration. Most of the studies to date have focused on prediction of ponding resu ...
  • Westhoff, M. C.; Savenije, H. H. G.; Luxemburg, W. M. J .; Stelling, G. S.; van de Giesen, N. C.; Selker, J. S.; Pfister, L.; Uhlenbrook, S. (European Geosciences Union, 2007-07-30)
    Distributed temperature data are used as input and as calibration data for an energy based temperature model of a first order stream in Luxembourg. A DTS (Distributed Temperature Sensing) system with a fiber optic cab ...
  • Ferre, Ty P. A.; Selker, John S. (American Geophysical Union, 2007-12-21)
    A new apparatus is presented that is capable of applying a constant fluid pressure at inflow and outflow boundaries. The apparatus can be refilled during operation and does not rely on an overflow mechanism. The device i ...
  • Tyler, Scott W.; Burak, Susan A.; McNamara, James P.; Lamontagne, Aurele; Selker, John S.; Dozier, Jeff (International Glaciological Society, 2008-12)
    Snowpack base temperatures vary during accumulation and diurnally. Their measurement provides insight into physical, biological and chemical processes occurring at the snow/soil interface. Recent advances in Raman-spec ...
  • Friesen, J.; van Beek, C.; Selker, J.; Savenije, H. H. G.; van de Giesen, N. (American Geophysical Union, 2008-12-13)
    A method for measuring whole-tree interception of precipitation is presented which employs mechanical displacement sensors to measure trunk compression caused by the water captured by the tree. This direct and nondestruc ...
  • Selker, J. S.; Suter, J. D.; Cuenca, R. H.; Flugstad, B. A.; Kelly, S. F. (American Geophysical Union, 2009)
    Measurement of soil hydraulic retention and conduction parameters using tension infiltrometers has been found to be useful but has suffered from unreliable instrument membranes at the soil interface and the need for manu ...
  • Tyler, Scott W.; Selker, John S.; Hausner, Mark B.; Hatch, Christine E.; Torgersen, Thomas; Thodal, Carl E.; Schladow, S. Geoffrey (American Geophysical Union, 2009-01-28)
    Raman spectra distributed temperature sensing (DTS) by fiber-optic cables has recently shown considerable promise for the measuring and monitoring of surface and near-surface hydrologic processes such as groundwater–su ...

  • Rupp, David E.; Keim, Richard F.; Ossiander, Mina; Brugnach, Marcela; Selker, John S. (American Geophysical Union, 2009-07-10)
    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 s ...
  • Weisbrod, Noam; McGinnis, Thomas; Rockhold, Mark L.; Niemet, Michael R.; Selker, John S. (American Geophysical Union, 2009-10-17)
    Surface tensions of high-salinity solutions are significantly different from those of pure water. Our objective was to develop and test a methodology to determine whether these surface tension effects predictably alter i ...
  • Selker, John (American Institute of Physics, 2010-06)
  • Sayde, Chadi; Gregory, Christopher; Gil‐Rodriguez, Maria; Tufillaro, Nick; Tyler, Scott; van de Giesen, Nick; English, Marshal; Cuenca, Richard; Selker, John S. (American Geophysical Union, 2010-06-05)
    Accurate methods are needed to measure changing soil water content from meter to kilometer scales. Laboratory results demonstrate the feasibility of the heat pulse method implemented with fiber optic temperature sensing ...
  • Steele‐Dunne, S. C.; Rutten, M. M.; Krzeminska, D. M.; Hausner, M.; Tyler, S. W.; Selker, J.; Bogaard, T. A.; van de Giesen, N. C. (American Geophysical Union, 2010-06-05)
    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 usi ...
