Creator:: Sayde, Chadi, Thomas, Christoph K., Wagner, James, and Selker, John
Abstract:: We present a novel technique to simultaneously measure wind speed (U) at thousands of locations continuously in time based on measurement of velocity-dependent heat transfer from a heated surface. Measuring temperature differences between paired passive and actively heated fiber-optic (AHFO) cables with a distributed temperature sensing system allowed estimation of...

Abstract:: Spatial resolution fiber-optic cables allow for detailed observation of thermally complex heterogeneous hydrologic systems. A commercially produced high spatial resolution helically wound optic fiber sensing cable is employed in the Dead Sea, in order to study the dynamics of thermal stratification of the hypersaline lake. Structured spatial artifacts were found...

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...

Creator:: Robinson, David, Selker, John, Bowden, Breck, Duncan, John, Durant, John, Hooper, Rick, Jacobs, Jennifer, and Knight, Rosemary
Abstract:: The Consortium of Universities for the Advancement of Hydrologic Sciences, Inc. (CUAHSI) began the Hydrologic Measurement Facility (HMF) program in June 2005 to advance hydrologic measurement capability within the research community. To provide guidance for this effort, a recent survey assessed the level of need among the hydrological sciences community...

Creator:: Selker, John, van de Giesen, Nick, Westhoff, Martijn, Luxemburg, Wim, and Parlange, Marc B.
Abstract:: 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. We illustrate the potential of this approach by quantifying both stream temperature dynamics and groundwater...

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...
