Proučevanje vpliva padajočega kamenja v varovalnem gozdu na Ljubelju : diplomsko delo - univerzitetni študij = Rock fall hazard assesment of protection forest on Ljubelj : graduation thesis - university studiesRebernik, JernejNad cesto, ki vodi do predora Ljubelj, so številni izvori kamenja, ki jo ogrožajo. Izločeni in popisani so bili poligoni z lastnosti terena in gozdni sestoji. Postavljenih je bilo 61 raziskovalnih ... ploskev, na katerih so bila popisana vsa živa drevesa s prsnim premerom večjim od 1,27 cm. Delež bukve v lesni zalogi je znašal 71 %, smreke 22 % in gorskega javorja 3 %. Porazdelitevdreves glede na debelinsko stopnjo je nakazovala negativno eksponentno porazdelitev, če je bila upoštevana samo bukev pa zvonasto, ki je nezaželena z vidika zagotavljanja trajnih varovalnih učinkov gozda. Priporočenje bil posek starejših bukovih dreves in s tem pospeševanje pomlajevanja. Območja ogroženosti zaradi padajočega kamenja so bila določena z računalniškima programoma Rockyfor3D, Rockfor.NET in metodo senčnega kota (funkcija Viewshed v programu ArcMap). Proučeno je bilo tudi, kako se ogroženost ceste spremeni, če so uporabljeni različni scenariji v simulacijah (brez gozda, gozd brez tras žičnega spravila, gozd z dejanskimi trasami, gozd s poševnimi vrzelastimi trasami, gozd s trasami po padnici terena in prebiralni gozd). Bilo je ugotovljeno, da med različnimi scenariji z gozdom ni bistvenih razlik, so pa razlike v velikosti ogroženih območij glede na uporabljeno metodo. Analize s programom Rockyfor3D upoštevajo največ dejavnikov in so najzahtevnejše, vendar dajejo najbolj zaupanja vredne rezultate.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
