Modelling System for the Pre-Design of Coastal Protection Works in Las Toninas, Argentina

Abstract

The need for protection of a coastal area of the town of Las Toninas (Province of Buenos Aires, Argentina), both due to its critical situation with respect to erosion but also to the presence of relevant submarine optic fiber cables, implies a detailed study of the possibility of implementation of an infrastructure project. Different alternatives of a system of detached breakwaters were analyzed, evaluating different aspects of the design of the work. To select the best option, a multi-model strategy was undertaken, resolving the detailed hydrodynamics (water levels, velocities and waves), sediment transport and the morphological evolution of the situation with the coastal works. Considering the results of the different models, the structural calculation of the breakwaters was carried out, defining its cross section and the materials to build it.
