COMPREHENSIVE STUDY AND MONITORING PROGRAM FOR BEACHES AT VIÃ‘A DEL MAR CHILE

On August 8th 2015, an extreme storm event affected central Chile. Significant wave heights up to 5.0 m at a depth of 20m were estimated in front of ViÃ±a del Mar. Beaches suffered massive erosion and relevant damage to coastal infrastructure occur (Figure 1), jeopardizing the touristic industry of the city. These episodes motivated the execution of the largest comprehensive study and monitoring plan ever done on the littoral system of ViÃ±a del Mar. The study considered reviewing historical records, hydrological analysis of the related river basins, several bathymetric and topographic surveys, sediment samples, measurements of waves and currents, monitoring cameras for field recording and extensive numerical modelling.
