Traditionally, Lorentzian geometry has been used as a necessary tool to understand general relativity, as well as to explore new genuine geometric behaviors, far from classical Riemannian techniques. Recent progress has attracted a renewed interest in this theory for many researchers: long-standing global open problems have been solved, outstanding Lorentzian spaces and groups have been classified, new applications to mathematical relativity and high energy physics have been found, and further connections with other geometries have been developed.

This book describes recent advances in the morphodynamics of mixed sand and gravel Mediterranean coasts, and provides updates and new methods for their study and management. It assesses how the differences in the geomorphic setting, in comparison with traditional sandy beaches, result in distinctive physical processes governing the dynamics of these coasts. Further, on the basis of field measurements, theoretical analysis and numerical modeling carried out at two study sites in southern Spain over the last 15 years, the book studies, analyzes and compares these physical processes and...
