Multicriterial analysis used for the optimisation of dike system management

Abstract

Levees are the most frequently used flood protection measure worldwide. In central Europe, they have been built systematically since the beginning of the 19th century. After the extreme regional floods in 1997, 2002 and 2013, the need arose for a more systematic and optimised approach to levee design and management, including the decommissioning of ineffective dike reaches. In this paper, a multicriterial algorithm is presented for the optimisation of levee management. The aspects considered are flood risk, economy, technical conditions, environmental issues and the consistency with general documents and principles in water management. The method is demonstrated via a case study of a levee subsystem in the upper Morava River basin.

Comprehensive Overview of Flood Modeling Approaches: A Review of Recent Advances

“…This involves examining how water will flow through a river or stream system and surrounding terrain, while taking factors like channel shape, roughness, and water velocity into consideration. The depth and extent of flooding in each area, as well as the location and timing of peak flows, may all be better understood using hydraulic modeling [48].…”

Understanding the impact of drought on Topľa River discharge seasonality

“…Snowfall is a contributing factor to the low-water season, which does not immediately generate runoff during periods of sub-zero temperatures resulting from partial or complete freezing of the stream (Wang, 2019). Understanding seasonal patterns of river flow is crucial for sustainable water management and agriculture (Serrano et al, 2020;Duchan et al, 2022). It can impact the quality and quantity of available water resources, affecting water supply, agriculture, and other waterdependent industries (Serrano et al, 2020;Khan et al, 2009).…”
