20.500.12556/RUL-125103 A review of measurement calibration and interpretation for seepage monitoring by optical fiber distributed temperature sensors Seepage flow through embankment dams and their sub-base is a crucial safety concern that can initiate internal erosion of the structure. The thermometric method of seepage monitoring employs the study of heat transfer characteristics in the soils, as the temperature distribution in earth-filled structures can be influenced by the presence of seepage. Thus, continuous temperature measurements can allow detection of seepage flows. With the recent advances in optical fiber temperature sensor technology, accurate and fast temperature measurements, with relatively high spatial resolution, have been made possible using optical fiber distributed temperature sensors (DTSs). As with any sensor system, to obtain a precise temperature, the DTS measurements need to be calibrated. DTS systems automatically calibrate the measurements using an internal thermometer and reference section. Additionally, manual calibration techniques have been developed which are discussed in this paper. The temperature data do not provide any direct information about the seepage, and this requires further processing and analysis. Several methods have been developed to interpret the temperature data for the localization of the seepage and in some cases to estimate the seepage quantity. An efficient DTS application in seepage monitoring strongly depends on the following factors: installation approach, calibration technique, along with temperature data interpretation and post-processing. This paper reviews the different techniques for calibration of DTS measurements as well as the methods of interpretation of the temperature data. hydrotechnics optical fiber DTS temperature seepage calibration data interpretation hidrotehnika DTS temperatura precejanje kalibracija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-03-04 15:08:43 2021-03-04 15:08:43 2022-09-05 03:49:33 0000-00-00 00:00:00 2020 0 0 23 str. iss. 19, art. 5696 Vol. 20 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 626/627 1424-8220 10.3390/s20195696 51392771 10176278 RAZ_Ghafoori_Yaser_2021.pdf RAZ_Ghafoori_Yaser_2021.pdf 1 894FE947DDD7E3FF7D7C4DEA804FCFA4 6adcbfbb958125bba9a6fd7005e4fb761b03b60a6f0f3e4313db5235ccc8ce2d 6005c5d0-7aa1-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153142 https://www.mdpi.com/1424-8220/20/19/5696 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140766 Fakulteta za gradbeništvo in geodezijo 0 0 0
