Multi criteria Analysis of Hydraulic Structures for River Training Works

Traditional selection of structural solutions in river training works are mainly focused on basic requirements as flood protection, coastal protection, protection of the river bed, providing the space for economic development. These solutions may lead to environmental degradation, i.e. alteration of physical-chemical and structural characteristics of the natural components of the environment, decrease of diversity and biological productivity of natural and anthropogenic ecosystems, impacts on the ecological balance and quality of life. These negative effects are also caused by the poor management and use of water, as well as inappropriate planning of the territory in general and river channels in particular. The main goal of this study was to present the approach for selection of hydraulic structures using multi criteria analysis, which would in addition to the basic requirements provide the ecological development of rivers and coastal rivers in accordance with the objective of sustainable development. For comparative review of alternative engineering solutions simplified ELECTRA method is applied.
