20.500.12556/RUL-185681 Soil moisture response and selected rainfall and antecedent VWC indices research data underlying the article Odziv vlažnosti tal ter izbrani indeksi padavin in predhodne vsebnosti vode v tleh (VWC) raziskovalni podatki, obravnavani v članku Soil moisture plays an important role in regulating natural processes, including water movement in the hydrological cycle. One of the main factors affecting soil moisture wetting and drying patterns is precipitation, but the response of soil moisture depends not only on its characteristics but also on other indicators such as soil depth, soil water-retention properties, land cover, and land use. These indicators determine the dynamics of the increase in soil moisture, which does not usually follow the dynamics of measured precipitation. In order to evaluate the rate of soil moisture response to rainfall input, as well as influence of rainfall indicators and previous soil moisture conditions on the increase, we applied decision tree model and random forest model. Data collected during two years of measurements at three different depths in a grassy area of a small park in Ljubljana were considered. The increase in soil moisture at depths of 16 cm and 51 cm is mainly determined by the maximum 20-minute intensity recorded in the period of 6 hours before the increase. In deeper layers (74 cm), however, the response is determined by the previous moisture conditions at least 24 hours earlier or by precipitation in the previous 7 days. Vlažnost tal ima pomembno vlogo pri uravnavanju naravnih procesov, vključno z gibanjem vode v hidrološkem krogu. Eden od glavnih dejavnikov, ki vplivajo na vsebnost vode v tleh, so padavine, odziv vlage v tleh pa je poleg lastnosti padavin odvisen še od drugih kazalnikov, kot so globina, vodozadrževalne lastnosti tal, tip dal, pokrovnost in raba tal. Ti kazalniki določajo s kakšno dinamiko bo prišlo do dviga vsebnosti vode v tleh, ki običajno ne sledi dinamiki merjenih padavin. Z namenom ocene hitrosti odziva vlažnosti tal na padavine ter analizo vpliva kazalnikov padavin in predhodne namočenosti tal na povečanje vsebnosti vode v tleh, smo uporabili model odločitvenih dreves in model naključnega gozda. Upoštevali smo podatke, zbrane v dveh letih meritev na treh različnih globinah na travnati površini majhnega parka v Ljubljani. Naraščanje vsebnosti vode v tleh na globinah 16 cm in 51 cm je pogojeno predvsem z maksimalno 20-minutno intenziteto, zabeleženo v obdobju 6 ur pred pričetkom naraščanja vrednosti. V globljih plasteh (74 cm) pa je odziv pogojen s stanjem predhodne vlažnosti vsaj 24 ur prej oziroma s padavinami v predhodnem obdobju 7 dni. soil moisture volumetric water content precipitation rainfall intensity antecedent conditions vlažnost tal prostorninska vsebnost vode padavine intenziteta padavin predhodne razmere true false false Repozitorij Univerze v Ljubljani Angleški jezik Slovenski jezik Department of Environmental Civil Engineering, Faculty of Civil and Geodetic Engineering, University of Ljubljana, Hajdrihova 28, Ljubljana, Slovenia / Oddelek za okoljsko gradbeništvo UL FGG, Hajdrihova 28, Ljubljana, Slovenija 2022, 2023 Raziskovalni podatki 2026-08-17 15:20:37 2026-08-17 16:04:51 2026-10-08 11:57:56 0000-00-00 00:00:00 2026 0 0 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 556 294238467 README.txt README.txt README 1 E27665F803599EA5A687E4D26EE1055E ffa4df50f2e8010d018ed891a6318454cf219e24124b1efe898f3832c70325d1 4c6ab299-9a3e-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244457 VWCresponse.xlsx VWCresponse.xlsx VWC response 1 CB014A641CD8C4C0401C442C3F9ACC7B 9b8b36aebecd761440f16bc00ac7773c964ccbab4438c9e7a2a8a6cad54d87c7 3ef37a1f-9a3e-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244456 Fakulteta za gradbeništvo in geodezijo Meritve in testi Meritve in testi: Fizično 0 0 0
