Age and Status Analysis of Hydraulic Structures Built in the Middle-Tisza Flood Defence Dike

Abstract

During the past decades, the record-breaking flood waves of the Tisza have highlighted that the affected flood protection facilities (earth dams, water construction structures, bulkheads, etc.) are resistant to excess pressure from high water pressure, if their load capacity and technical conditions are adequate. In this article, the author prepares an age pyramid based on the age of the hydraulic structures built in the main line of the Middle Tisza flood defence, about which a comprehensive analysis has been carried out. It reveals the relationship between the age pyramid and the technical conditions, and makes proposals for making maintenance and renovation works more efficient and for improving the technical state of elements.
