Water balance of municipal landfill SežanaRustja, Damjan (Avtor) Brenčič, Mihael (Mentor) Vidmar, Ines (Komentor) LandfillKarstHydrologic Evaluation of Landfill Performance (HELP) numerical modelWater balance modellinglandfill coverSežanaThe Sežana municipal waste landfill closed in 2015 after having been operational for more than 50 years. Ever since, efforts have been made in order to monitor, discern and remediate the effects of the old landfill onto the environment. Moreover, the mere fact CERO Sežana is located on the extremely vulnerable karstic Kras plateau adds levels of significance to the closure process. The thesis is intended to provide an in-depth analysis of leachate production within the waste-body in addition to its significance in comparison to the overall water balance of the karstic aquifer. In order to perform this analysis two separate water balance models had to be constructed. Firstly, a water balance model of the Kras massive was created using existing data in conjunction with data obtained from flow measurement stations. Secondly, a Hydrologic Evaluation of Landfill Performance (HELP) numerical model was produced. Ultimately quantitative and qualitative data was discerned from each model. Combining and comparing the results gave us valuable insight into the influence of the landfill.D. Rustja20232023-12-01 09:00:03Magistrsko delo/naloga152628UDK: 55VisID: 98003COBISS_ID: 177393411sl
