People used moderate natural resources and obeyed the natural laws. Last Century of the II millennium constitutes a turning point in the relations, since it brought into question the harmony between people and the natural environment. The concept of „sustainable development“ is development which meets the needs of the present providing the ability of future generations to meet their own needs. The aim of this concept refers to the continuous improvement of quality of life and cannot be achieved if the community is not able to rationally and effectively use natural resources and ecological potential of the economy, providing an unbreakable link between economic prosperity, environmental protection and public interest. Water is an important natural resource. Engineering solutions for river training structures have a strong and long-lasting impact on the economy and society in general. Traditional structural solutions in river training works are focused on basic requirements as flood protection,
littoral zone protection, river bed protection, providing the space for economic development. These solutions may lead to environmental degradation, i.e. alteration of physical-chemical and morphological 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. The main purpose of this thesis was to define a approach for the selection of hydraulic structures using multi criteria analysis, that would in addition to the basic water management requirements (flood protection, coastal protection, protection of the river bed, securing the space for economic development) provide the ecological development of rivers in accordance with the requirements of the „sustainable development“. This thesis elaborates on the application of multi criteria analysis method in selecting an appropriate alternative river training proposed solution for the section of the river course. Presented method is an aid to decision-making that helps stakeholders organize available information, think on the consequences, explore their own wishes and tolerances. Approach presented is based on the author's selection of sustainability criteria and identifies the best solution for the sustainable development of the river system, regarding to the environmental impact of proposed river training structural solution. In the case study section of the river in lower part of Carpathian Mountains is considered, for which three relevant intended alternative solutions are designed: riverbed with concrete lining, riverbed slope protection with vii gabions/gabion mattresses and natural (unregulated) riverbed. For alternative solutions respectable comparison the ELECTRE and PROMETHEE GAIA methods were applied, which allow comparison of different criteria unit measures. The main difference in the application of these methods is in defining the criteria weights, which in the method ELECTRE are exclusively subjective, while in a PROMETHEE GAIA method a respectable comparison of three scenarios of application of subjective, objective and integrated subjective and objective weights for criteria are given. For the analysis of the three scenarios defined alternatives, complete ranking of PROMETHEE GAIA method was performed using the software package Decision Lab 2000. In the case study, the final ranking of alternative solutions in both methods indicates that design of second structural solution is sustainable. MCA is not a tool providing the „right“ solution in a decision problem, since no such solution exists. The solution provided might be considered best only for the stakeholders who provided their values in the form of weighting factors, while other stakeholders’ values may indicate another alternative solution. Results obtained in the work and the conclusions derived have general character and can be applied in all areas of water management in the selection of optimal hydraulic constructive solutions.View More
