Analysis of the effectiveness of the coastal protection method : Maltais-Savard ears system (SEMS)

The project involves evaluating the effectiveness of a beach restoration technique. The aim of this method is to counter the erosion of a sandy coast dominated by waves and tides and, more particularly in this case, to compensate for the end effect generated by the riprap. This project is continuing the work already undertaken in the year 2000 on a qualitative and quantitative analysis of the operation of a new type of coastal protection structure, consisting of an ears system called the Maltais-Savard ears system (SEMS). It was launched by the Comité ZIP de la Rive Nord de l'estuaire and the original concept of this system was invented by MM Lucien Maltais and Jean-Pierre Savard. The SEMS concept is based on the results of eight-year (1992-1999) field trials on a beach located in Baie Saint-Ludger (BSL), in the municipality of Pointe-aux-Outardes, Quebec, Canada.
