This reprintshows recent advances in dam safety related to overtopping and the prevention, detection, and risk assessment of geostructural risks. Related to overtopping, the issues treated are: the throughflow and failure process of rockfill dams; the protection of embankment dams against overtopping by means of a rockfill toe or wedge-shaped blocks; and the protection of concrete dams with highly convergent chutes. In the area of geostructural threats, the detection of anomalies in dam behavior from monitoring data using a combination of machine learning techniques, the numerical modeling of seismic behavior of concrete dams, and the determination of the impact area downstream of ski-jump spillways are also studied and discussed. In relation to risk assessment, three chapters deal with the development of fragility curves for dikes and dams in relation to various failure mechanisms.

This Special Issue "Application of Wood Composites" addresses various aspects of these important wood materials’ use. Topics include the mechanical processing of wood composites, including their cutting, milling, or sanding, incorporating current analysis of wood dust or grain size measurements and the composition of particles; scientific views on the influence of various adhesives in the creation process of wood composites and the analysis of their behavior in contact with various wood elements under different conditions; the analysis of input raw materials forming wood composites, including various wood species, but also non-wood lignocellulosic raw materials; and, last but not least, the analysis of bark, which in recent years has become an important and promising raw material involved in the construction of wood composites. The study of the development of the sliding table saw also suitably complements this Special Issue.
