In this paper, 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.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 inflows to the Maisbich, a first-order stream in Luxembourg (49°47?N, 6°02?E). The technique provides a very rich dataset, which may be of interest to many types of environmental research, notably that of stream ecosystems.read more

TL;DR: The Prediction in Ungauged Basins (PUB) initiative of the International Association of Hydrological Sciences (IAHS) launched in 2003 and concluded by the PUB Symposium 2012 held in Delft (23-25 October 2012), set out to shift the scientific culture of hydrology towards improved scientific understanding of hydrological processes, as well as associated uncertainties and the development of models with increasing realism and predictive power as discussed by the authors.

Estimating groundwater recharge
TL;DR: In this article, a critical evaluation of the theory and assumptions that underlie methods for estimating rates of groundwater recharge is provided, with detailed explanations of the methods provided - allowing readers to apply many of the techniques themselves without needing to consult additional references.

Pursuing the method of multiple working hypotheses for hydrological modeling
TL;DR: In this paper, the authors advocate using the method of multiple working hypotheses for systematic and stringent testing of model alternatives in hydrology and discuss how the multiple-hypothesis approach provides the flexibility to formulate alternative representations describing both individual processes and the overall system.

Heat as a tracer to determine streambed water exchanges
TL;DR: A review of relevant literature suggests researchers often graphically visualize temperature data to enhance conceptual models of heat and water flow in the near-stream environment and to determine site-specific approaches of data analysis as discussed by the authors.

Multiscale thermal refugia and stream habitat associations of chinook salmon in northeastern oregon
TL;DR: In this article, the authors investigated the effectiveness of thermal remote sensing for analyzing spatial patterns of stream temperature and assessed habitat selection by spring chinook salmon, evaluating whether thermal refugia might be responsible for the persistence of these stocks in rivers where water temperatures frequently exceed their upper tolerance levels (258C) during spawning migration.

Interaction between stream temperature, streamflow, and groundwater exchanges in alpine streams
TL;DR: In this paper, four alpine streams were monitored to continuously collect stream temperature and streamflow for periods ranging from a week to a year, and it was shown that evapotranspiration losses determined diurnal streamflow variations in the gaining reaches, while in the losing reaches, evapotspiration losses were compounded by diurnal variations in streambed infiltration.

Preliminary observations of streamflow generation during storms in a forested Piedmont watershed using temperature as a tracer
TL;DR: In this paper, a 41-ha forested watershed at Panola Mountain in the Georgia Piedmont showed that the initial rapid hydrologic response is caused by a combination of groundwater discharge and channel interception of rainwater.
