“…The GIS-MCDA was used for the selection of the most suitable test surface. Two concepts were used: Boolean and continuous values [47]. The Boolean approach, which serves to limit the alternatives under consideration, relies on the binary statement (true/false) of the criteria for a considered goal or decision [48].…”

Tufa sedimentary systems are sensitive fluvial landscapes subject to various external disturbances. Tufa landscape degradation reflected in negative hydrological changes and a decrease in the intensity of the tufa formation process have been detected in National Park Krka (Croatia). The main causes were recognized in the uncontrolled spread of invasive vegetation (Ailanthus altissima) and increased anthropogenic influence. Therefore, the Park administration launched the project, Management and Maintenance of Macro-Vegetation at Skradinski Buk (SB)—Development of a Multicriteria Model for Sustainable Management. The methodological framework was divided into three scales of research. The macro-scale research comprised a set of activities aimed at selecting the most suitable test surface within a wider area of the Skradinski Buk (SB) waterfall. The meso-scale research involved mapping the reference and final state of the vegetation and hydrological network after the removal of invasive vegetation and mitigation of negative anthropogenic impact. At the micro-scale, a monitoring system was established to track the quality of the tufa sedimentary system. Special emphasis was placed on the measurement of tufa formation dynamics (TFD) on limestone plates using a new methodological approach based on structure from motion (SfM) photogrammetry. Implementation of the proposed multiscale framework resulted in reactivation of tufa-forming watercourses, prevention of invasive vegetation regeneration and achievement of sustainable conditions for the tufa formation process. In reactivated watercourses, the average tufa growth rate was 4.267 mm a−1 (n = 18). Potential users of this framework include local authorities and administrators of protected areas.

“…With several hundred recorded active gullies [89,90] Pag Island can be considered as a very suitable location for gully erosion research. Overall, studies considering soil erosion in Croatia are scarce [89][90][91][92][93], especially in regard to the application of modern geospatial technologies and advanced research methods for temporal monitoring of spatio-temporal changes. Therefore, thorough longitudinal research of gully erosion is of crucial importance for a better understanding of the intensity of overall soil erosion dynamics.…”

Gully erosion is one of the most prominent natural denudation processes of the Mediterranean. It causes significant soil degradation and sediment yield. Most traditional field methods for measurement of erosion-induced spatio-temporal changes are time and labor consuming, while their accuracy and precision are highly influenced by various factors. The main research question of this study was how the measurement approach of traditional field sampling methods can be automated and upgraded, while satisfying the required measurement accuracy. The VERTICAL method was developed as a fully automated raster-based method for detection and quantification of vertical spatio-temporal changes within a large number of gully cross-sections (GCs). The developed method was tested on the example of gully Santiš, located at Pag Island, Croatia. Repeat unmanned aerial vehicle (UAV) photogrammetry was used, as a cost-effective and practical method for the creation of very-high-resolution (VHR) digital surface models (DSMs) of the chosen gully site. A repeat aerophotogrammetric system (RAPS) was successfully assembled and integrated into one functional operating system. RAPS was successfully applied for derivation of interval (the two-year research period) DSMs (1.9 cm/pix) of gully Santiš with the accuracy of ±5 cm. VERTICAL generated and measured 2379 GCs, along the 110 m long thalweg of gully Santiš, within which 749 052 height points were sampled in total. VERTICAL proved to be a fast and reliable method for automated detection and calculation of spatio-temporal changes in a large number of GCs, which solved some significant shortcomings of traditional field methods. The versatility and adaptability of VERTICAL allow its application for other, similar scientific purposes, where multitemporal accurate measurement of spatio-temporal changes in GCs is required (e.g., river material dynamics, ice mass dynamics, tufa sedimentation and erosion).

“…Within this research GAMA method was used for modelling of gully erosion susceptibility, based on 10 erosion predisposing criteria and one constraining (Boolean) factor. Gully erosion susceptibility modelling was performed on example of Pag island, Croatia, and research results are published in separate article [10], while this article concentrates entirely to the explanation of the developed GAMA method. Since GAMA method is applicable to various GIS-MCDA susceptibility modelling purposes we are encouraging its future use and therefore open-source GAMA method toolset can be acquired for research purposes through the official web page of Geospatial Analysis Laboratory (htps://gal.unizd.hr).…”

“…All existing CWC methods have certain advantages and disadvantages, depending on the research aims and purpose [11]. Generally, one of the most frequently used CWC method is analytical hierarchical process (AHP) [[16], [17], [18]], which was successfully applied within application of GAMA method for gully erosion susceptibility modelling [10]. For complex comparisons of different CWC methods, sensitivity analysis and model validation, we suggest using simpler tools (e.g.…”
