Levees Condition Assessment in Croatia

Levees are long linear structures where often there is insufficient or unavailable data from the preliminary design to maintenance during exploration and monitoring. Their importance is in the first place the protection of human life and material and other goods. In Croatian history the levees are almost always built when there is the need for flood defence or to improve the existing system of protection against adverse effects of water. Such actions are mainly implemented without the required geotechnical investigations, internal regulations and the prescribed monitoring of levees. But levees are not static structures, and nor is the high water level on which the levees are designed. In the Republic of Croatia in the last ten years extreme hydraulic phenomena have been recorded which influenced the levees. Because of such construction conditions and the levees' aging there is a need for serious systematization of the state of levees. Due to the impact, but also the significance of levees, it is important to maintain their safety and therefore continue to implement monitoring. This article proposes monitoring the levees through assessment of the levees and foundation and levee data collection. The article describes negative effects on the levees, indicators that should be monitored, the importance of levee assessment, and the guidelines and recommendations for levee assessment implementation. Appropriate geotechnical investigations and monitoring provide the levee assessment and give a timely response which is due to the information of the possible collapse modes or levee deterioration. The systematic levee monitoring and the data obtained by geotechnical investigations, measurements, and even the very visual observation and the resulting levee assessment provide a great opportunity to use in designing, building, construction and new levee exploration.
