Creator:: Bense, V. F, Hochreutener, R., Bour, O., Le Borgne, T., Lavenant, N., and Selker, J. S.
Abstract:: We develop an approach for measuring in-well fluid velocities using point electrical heating combined with spatially and temporally continuous temperature monitoring using distributed temperature sensing (DTS). The method uses a point heater to warm a discrete volume of water. The rate of advection of this plume, once the heating is...

Creator:: O'Donnell Meininger, T. and Selker, J. S.
Abstract:: Error in distributed temperature sensing (DTS) water temperature measurements may be introduced by contact of the fiber optic cable sensor with bed materials (e.g., seafloor, lakebed, streambed). Heat conduction from the bed materials can affect cable temperature and the resulting DTS measurements. In the Middle Fork John Day River, apparent...

Creator:: Stewart, R. D., Liu, Z., Rupp, D. E., Higgins, C. W., and Selker, J. S.
Abstract:: Accurate measurement of the amount and timing of surface runoff at multiple scales is needed to understand fundamental hydrological processes. At the plot scale (i.e., length scales on the order of 1–10 m) current methods for direct measurement of runoff either store the water in a collection vessel, which is...

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...

Creator:: Read, T., Bour, O., Selker, J. S., Bense, V. F., Le Borgne, T., Hochreutener, R., and Lavenant, N.
Abstract:: We show how a distributed borehole flowmeter can be created from armored Fiber Optic cables with the Active-Distributed Temperature Sensing (A-DTS) method. The principle is that in a flowing fluid, the difference in temperature between a heated and unheated cable is a function of the fluid velocity. We outline the...

Creator:: Arnon, Ali, Lensky, N. G., and Selker, J. S.
Abstract:: The thermal stratification of the Dead Sea was observed in high spatial and temporal resolution by means of fiber-optics temperature sensing. The aim of the research was to employ the novel high-resolution profiler in studying the dynamics of the thermal structure of the Dead Sea and the related processes including...

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...

Creator:: Bailey, D. R., Owen, J. S., Wagner, J., and Selker, J. S.
Abstract:: Many nurseries are considering soil moisture sensor networks to improve water application efficiency. Due to the necessarily wide distribution of sensors at a nursery, a wireless network is easier to install, more flexible, and can be scaled up as needed without re-design as compared to a traditional wired sensor network....
