    International audienceExperts take into account several criteria to assess the effectiveness of torrential flood protection systems. In practice, scoring each criterion is imperfect. Each system is assessed choosing a qualitative class of effectiveness among several such classes (high, medium, low, no). Evidential Reasoning for Multi-Criteria Decision-Analysis (ER-MCDA) approach can help formalize this Multi-Criteria Decision-Making (MCDM) problem but only provides a coarse ranking of all systems. The recent Belief Function-based Technique for Order Preference by Similarity to Ideal Solution (BF-TOPSIS) methods give a finer ranking but are limited to perfect scoring of criteria. Our objective is to provide a coarse and a finer ranking of systems according to their effectiveness given the imperfect scoring of criteria. Therefore we propose to couple the two methods using an intermediary decision and a quantification transformation step. Given an actual MCDM problem, we apply the ER-MCDA and its coupling with BF-TOPSIS, showing that the final fine ranking is consistent with a previous coarse ranking in this case

Π’he geographical area of research includes: Topciderska River, Toplica River and Rasina River Watershed, which are classified in the sub-watershed system. Π’he values of criteria for estimating soil erosion are: land use, soil erodibility, rainfall erosivity factor and topographical factor (RUSLE method), as well as the value of 10 morphometric parameters used to estimate the risk of torrential floods (sub-watershed area, relative slope of the river bed, the mean sub-watershed slope, the coefficient of erosion energy of relief, geomorphological-erosion coefficient) are established by using relevant maps and GIS technique. In the paper, there have been applied various methods of multi-criteria analysis, such as: AHP, WSM, ELECTRE II PROMETHEE II. Using these methods, criteria weights are determined, and sub-watershed ranking is performed according to the vulnerability to erosion and torrential flooding. The first order sub-watershed, represents the area where implementation of conservation measures should be urgently performed. The above-mentioned multi-criteria analysis methods have been applied for: selection of watersheds for check dam construction (such a technical work in the bed of torrential streams), then, a selection of the most appropriate combination of check dams, as well as profiles for their construction. In the field are registered damage of check dam, and based on this, the formula for prioritizing the rehabilitation of check dams is proposed. Multi-criteria optimization methods (Constrained method and Method of weight coefficients) have been used for the selection of the optimal structure of land use in the sub-watershed, as well as the optimization of terrace construction as a conservation measure. A model of integrated watershed management has been proposed, where the application of the multi-criteria analysis method, would provide a selection of the most appropriate combination of measures and works for the reduction / prevention of erosion and torrents
