Prebiralne pregrade na hudournikih v Sloveniji

Turel, Miha (author), Kobal, Milan (mentor)

Prebiralne pregrade so prečni objekti na hudournikih. Njihova primarna funkcija je zadrževanje lesenega plavja ter plavin in kontrolirano prebiranje manjših frakcij plavin dolvodno po strugi in s tem obnavljanje posteljice struge. Cilj diplomskega dela je bil popis točnih lokacij in stanja prebiralnih pregrad v Sloveniji. Terenski del diplomske naloge smo opravili na štirih od osmih vodnogospodarskih območjih (VGO) v Sloveniji in sicer na VGO zgornje Save, VGO Drave, VGO Savinje in VGO Soče. Podatke o lokacijah prebiralnih pregrad smo pridobili od predstavnikov podjetij, ki opravljajo gospodarsko javno službo (GJS) na področju urejanja voda. Vsaki prebiralni pregradi smo izmerili dimenzije, jo fotografirali in ocenili njeno stanje. V Sloveniji je 24 prebiralnih pregrad, od tega največ (11) na VGO zgornje Save in najmanj (2) na VGO Drave. Na VGO Savinje se nahaja 6 prebiralnih pregrad na VGO Soče pa se jih nahaja 5. Od 24 prebiralnih pregrad jih 20 opravlja prebiralno funkcijo, 4 pa zaradi prevelike zapolnjenosti zaplavnega prostora funkcije zadrževanja lesenega plavja in plavin ter kontroliranega prepuščanja manjših frakcij plavin ne opravljajo več. Podatke iz terena smo uvozili v geografski informacijski sistem GIS in izdelali podatkovno bazo o lokacijah in stanju prebiralnih podlag v Sloveniji.

• Title: Open check dams on torrents in Slovenia

Abstract

Open check dams are structures transversely placed on torrents. Their primary function is large woody debris (LWD) and sediment retention and controlled filtering of smaller fractions of sediment, therefore assuring contribution of renewing the riverbed downstream. The goal of the diploma thesis was to determine exact locations of open check dams in Slovenia and their condition. The field part of the diploma thesis was completed in four out of eight water management areas (WMA) in Slovenia, namely the Upper Sava WMA, the Drava WMA, the Savinja WMA and the Soča WMA. Data on locations of open check dams were obtained from representatives of companies performing the public utility service (PUS) in the field of water management. We measured the dimensions of each open check dam, photographed it and assessed its condition. There are 24 open check dams in Slovenia, of which the most (11) are located in the Upper Sava WMA and the least (2) are located in the Drava WMA. There are 6 open check dams in the Savinja WMA and 5 in the Soča WMA. Out of 24 open check dams, 20 are still performing its primary function, and 4 don't due to overfilling of the accumulation space behind the open check dam. We imported data gathered on the field into the GIS geographic information system and created a database on the locations and condition of the open check dams in Slovenia.
