20.500.12556/DiRROS-20539 Seepage detection using passive temperature measurements by fiber optic DTS This article is an extended abstract of the doctoral dissertation “Optimization of early seepage detection in embankments using a distributed temperature system based on fiber optic sensing” [1]. Distributed Temperature Sensors (DTS) measure temperature precisely with high spatial resolution, enabling seepage flow detection through the interpretation of temperature measurement. Active DTS measurement which introduces heat into the soil to monitor its dissipation, has been extensively studied for seepage detection. However, the potential of passive measurement, which measures natural soil temperature, for seepage detection demands further exploration. The doctoral research investigated the capability of passive DTS measurements for seepage detection. The findings show that passive DTS detects very small temperature variations as a result of the seepage flow. Additionally, the results offer valuable insights into the coupled hydro-thermal behavior and the influence of seepage on heat transfer. The thesis classified and compared different techniques for temperature data calibration and interpretation. Furthermore, an interpretation approach based on numerical simulation and a fully dynamic calibration technique was developed. optical fiber DTS soil emperature seepage optično vlakno DTS zemljina temperatura pronicanje true false true Informatika Angleški jezik Slovenski jezik © Slovenian Society Informatika, 2024 Neznano 2024-10-16 12:59:24 2024-10-16 13:13:18 2024-10-17 03:36:12 0000-00-00 00:00:00 2024 0 0 str. 285–288 no. 2 Vol. 48 Jun. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-03-26 535 1854-3871 10.31449/inf.v48i2.5750 209516547 https://doi.org/10.31449/inf.v48i2.5750 1 b5c71f37-8bad-11ef-89f3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28973 RAZ_Ghafoori_Yaser_2024.pdf RAZ_Ghafoori_Yaser_2024.pdf 1 E14C9F40311986CEBDFA7097A7D348E4 6cdbd5e79dc6671a38f5e6218a6d137d6740ede7ca4905a1749dc7a43e95815e c5c419e2-8bae-11ef-89f3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28974 Zavod za gradbeništvo Slovenije 0 0 0
