The Use of AHP Method for the Determination of the Most Environmentally Beneficial Variants of Barrages

This study presents an attempt to apply the AHP (Analytic Hierarchy Process) method for the determination of the most beneficial concept of development of a barrage. The main focus of the analysis was the influence of the civil engineering structure on various elements of the environment. The AHP method was applied to analyse the influence of specific scenarios on environmental elements and on the overall objective. Basing on the analysis, local and global priorities were determined for individual elements of the created decision tree, which allowed us to select the most beneficial scenario. The scenarios referred to the existing hydraulic structures located on the rivers Głomia, Gwda and Prosna. In order to verify the obtained results, calculations of the consistency of the importance evaluations for specific criteria were performed
