Abstract:We present an methodology for a more detailed and less ambiguous spatial structure interpretation of small, shallow landslides. The spatial structure interpretation of this type of landslides bases on both underground and surface models and requires high-density data. This methodology involves the use of ground-penetrating radar (GPR), electrical resistivity tomography (ERT) and terrestrial laser scanning (TLS) techniques. GPR technique, used for the definition of the underground structure model, provides a time-efficient survey that yields high-resolution data, making it suitable for a shallow subsurface analysis. ERT technique was used only to confirm the results obtained by the GPR survey, since it is more time consuming and more convenient for larger and deeper landslides investigations. The surface model is created using TLS technique, which is time- and cost-effective, produces a large amount of data and is favourable for smaller areas, such as the analysed type of landslides. To the best of the authors’ knowledge, existing procedures based on either conventional or non-invasive geophysical methods, observe, almost exclusively, larger and deeper landslides. Their real-time monitoring involves a number of sensors and is hardly applicable to small landslides because of their number, location and dimensions. Considering the benefits of each applied technique and the interpretation of the results obtained from field data, it is clear that the main advantages of the realized application are the efficiency and applicability for small shallow landslides whose number and impact on the environment are dominant. Therefore, it represents a solid basis for landslide mitigation. The verification of the methodology was made on a small, shallow landslide in the village of Vinča, near Belgrade, Serbia.

Title:Razlaga prostorske strukture plitvega plazišča z uporabo različnih geofizikalnih metod
Abstract:Predstavljamo metodologijo za natančnejšo in manj negotovo prostorsko strukturno razlago majhnih, plitkih plazišč. Razlaga prostorske strukture to vrstnih plazov temelji na podzemnem in površinskem modelu in zahteva veliko gostoto podatkov. Ta metodologija vključuje uporabo metod georadarja (GPR), električne upornostne tomografije (ERT) in lasersko skeniranje površja (TLS). GPR metoda, s katero določamo podzemeljski strukturni model, je časovno učinkovita in daje podatke visoke resolucije, zato je primerna za analize plitvega podpovršja. ERT metodo uporabimo samo za potrditev dobljenih rezultatov z GPR preiskavami, ker je dolgotrajna in primernejša preiskava za večja in globlja plazišča. Površinski model je ustvarjen z uporabo TLS metodo, ki je časovno in stroškovno učinkovita, z njo dobimo veliko podatkov in je primernejša za manjše površine, kot so analizirani tipi plazišč. Kakor nam je znano, se obstoječi postopki, ki temeljijo na običajnih ali neudarnih geofizikalnih metodah, uporabljajo izključno za opazovanje večjih in globljih plazišč. Njihovo sprotno opazovanje vključuje številne senzorje zato se težko uporablja na majhnih plaziščih zaradi njihovega števila, mesta in obsega. Ob upoštevanju prednosti vsake uporabljene metode in razlage rezultatov s terena, je jasno, da je največja prednost opravljene študije njena učinkovitost in uporabnost za majhna plitva plazišča, čigar število je veliko in vpliv na okolje prevladajoč. Zato je lahko dobra osnova za olajšano obdelavo plazišč. Metodologijo smo preverili na majhnem, plitvem plazišču v vasi Vinča, blizu Beograda v Srbiji.
