IzvlečekErozija predstavlja pomemben eksogeni proces, ki je prisoten na skoraj vsakem delu Zemljinega površja in tudi slovensko ozemlje ni izjema. Stopnja erozije je močno odvisna od dejavnikov, vezanih na lastnosti površine kot so tip rabe tal, tip vegetacijskega pokrova in geomorfologija ter od dejavnikov, vezanih na podnebje kot sta padavinski režim in nihanja temperature. Prispevek obsega modeliranje mehanske erozije in transport delcev po površju s pomočjo vode, cilj pa je bil združiti splošno uveljavljeno metodologijo RUSLE, ki učinkovito modelira ploskovno erozijo z metodo ocene stopnje podvrženosti eroziji v strugah. Združeni metodi uspešno modelirata erozijo v izrazito goratih in kraških območjih. Za testno območje je bilo izbrano območje občine Bohinj, kjer so zaradi geomorfološke razgibanosti terena prisotni številni naravni površinski procesi, idealno za razvoj združenega modela erozijski h območij. AbstractErosion is an important exogene process that can be found on almost all surfaces around the globe and Slovenian territory is no exception to the rule. The extent of the erosion is a result of various factors linked to the surface properties, such as land use type, vegetation type, and geomorphology and of the factors linked to the climate, such as the precipitation regime and the temperature oscilation. The paper focuses on the modelling of the mechanical erosion and the surface transport of particles due to surficial waters. The aim of the research was to combine the RUSLE surface erosion method with a model of gully erosion. The combined approach successfuly models the erosion in the mountainous and karst areas. Due to its vivid geomorphology that results in various natural surface proceses the area of Bohinj municipality was chosen as an ideal case study for testing the joint methodology. Uvod V znanostih, ki se ukvarjajo s procesi na Zemljinem površju, predstavlja erozija površin-ske procese, pri katerih pride s pomočjo delovanja vode ali vetra do mehanskega prenosa trdnih delcev kamnin ali tal, ali kemičnega prenosa raztopin z ene lokacije na drugo (Toy et al., 2002). Erozijski procesi se glede na vzrok in način transporta delcev delijo na ploskovno, rečno, obalno, kemično, ledeniško, poplavno in vetrno erozijo ter pobočne masne premike (Zachar, 1982;Toy et al., 2002). Prisotnost številnih strug na območju ocene stopnje erozivnosti, predstavlja za kvaliteno oceno le-te z modelom RUSLE precejšni izziv.
