TL;DR: In this article, the authors discuss the spectrum of fiber-optic tools that may be employed to make these measurements, illuminating the potential and limitations of these methods in hydrologic science.

TL;DR: 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.

TL;DR: In this article, a DTS (Distributed Temperature Sensing) system with a fiber optic cable of 1500 m was used to measure stream water temperature with 1 m resolution each 2 min.

TL;DR: The assumption of stationarity has been criticised by as mentioned in this paper, who argued that when compared with the temporal, spatial, or topical extent of the questions posed to hydrology, such conditions could indeed be considered stationary, and therefore the neglect of certain long-term non-stationarities or feedback effects (even if they were known) would not introduce a large error.

TL;DR: This work proposes three different types of "functional units" – specialized HRUs – which behave similarly with respect to one specific form of water release and with a characteristic extent equal to one of those three scale levels, and discusses an experimental strategy based on exemplary learning and replicate experiments to identify and delineate these functional units.
