Abstract: Shoreline mobility and erosion is an important scientific, technical and management issue to take into consideration along almost all the coastal regions. High energetic wave and tidal action dominate the extremely diverse nature of the North Atlantic west coast and this represents a challenge when compared with other coasts. The natural and the anthropogenic forcing has evolved into several high risk situations for urban settlements and economic activities. Climate change probably will increase the existent risk level. The sandy coastal stretch Cova do Vapor - Costa da Caparica near the Tagus river mouth (Portugal, Lisbon area) is influenced by a high wave action. Since 1870, important physiographic transformations and retreat events of the coastline has been occurring. The study of alternative scenarios of management and coastal protection in highly vulnerable and edge risk areas, based on scenarios of shoreline mobility, led to design and implementation of several mixed solutions. Based on a 17 years� scientific and technical experience, the paper will present and discuss the geographic and historic framework of the urban development, the erosion process and coastal defense interventions, coastal management and coastal protection of the urban seafront, the described interventions, the construction phases, the bathymetric survey and sediment balance
