“…Aki & Richards 1980), in which the unknowns are the displacement and traction on the boundary (Kawase 1988; Kawase & Aki 1989, 1990; Zhang & Chopra 1991). The formulation of the latter, however, is derived from the Somigliana representation (Sánchez‐Sesma & Campillo 1991, 1993; Sánchez‐Sesma & Luzon 1995; Yokoi & Sánchez‐Sesma 1998; Gil‐Zepeda et al 2002). These methods were successfully applied to solving the scattering problems caused by various irregular topographies or complex alluvium basins encountered in seismological study.…”

SUMMARY We propose a new approach to study the scattering problem of seismic waves by an irregular topography. It is rooted in the Bouchon–Campillo method that can provide accurate enough solutions for most of the problems, but the expensive computation cost, especially for the high‐frequency problem, limited its application. In this study, we develop a new approach to study seismic waves scattering problem by an irregular topography, in which only those sampling points over the irregular part of surface topography are directly solved; thus the number of unknowns is greatly reduced. Comparisons with analytical solution and other existing validated methods show the computational efficiency of our new method is much superior to the original Bouchon–Campillo method, and is expected to be a powerful tool in simulating the seismic wave scattering problem by an arbitrary topography.

Abstract. The diversion of natural river courses and subsequent filling by alluvial deposits or anthropic intervention has been hidden by urban development in the majority of the cities. The research we conducted involved monitoring the evolution of a river course and reconnaissance of the original morphology of the fluvial systems. Our research was applied to the section of the River Beiro that flows through the city of Granada, Spain. The research has been carried out using geo-technical methodology based on reconnaissance via dynamic penetration. This allowed us to determine the different degrees of consolidation and compaction in the areas corresponding with the former course of the river, which are now filled by alluvial deposits. In addition, we have backed up our findings with information provided by historical maps of the city of Granada. The results have identified an area wherein buildings are at risk, as evidenced by the detrimental effects registered in the buildings in this area.
