Coastal Sediment Management Plan (CSMP) for Sandy Coasts: A Tool for Current and Future Coastal Erosion

This article discusses the necessity and methodology of developing a Coastal Sediment Management Plan (CSMP) for regions exposed to coastal erosion. It emphasizes the importance of long-term vision and sustainable coastal management in the face of increasing erosion, population growth, and sea-level rise. The case study of the Coastal Sand Management Plan of Languedoc-Roussillon in France is presented, showcasing the evolution of the plan, priority sites, and restoration efforts.

  1. The necessity of Coastal Sediment Management Plan (CSMP) elaboration in regions exposed to coastal erosion: a management tool for the current and future sandy coasts Olivier RAYNAL, Raphaël CERTAIN, Bénédicte GUERINEL Biarritz 21/10/2011

  2. Introduction In the first time (1970 in Languedoc-Roussillon)… Eroded sandy coast + Growth of population and economy in coastal area Development of artificial coastline Punctual measurements And now… Coast erosion increasing + Growth of population and economy in coastal area + Sea-level rise Development of a sustainable and global (regional scale) coastal management, with a long-term vision

  3. Coastal Sand Management Plan methodology international ICZM and CSMP review:

  4. The Coastal Sand Management Plan of Languedoc-Roussillon > 220 km of coastline > 4 departments and 30 « districts » > 28 % of artificial coast > 24 % of eroded coast

  5. Sedimentary dynamics change The Coastal Sand Management Plan of Languedoc-Roussillon Century evolution of sand budget 1970’s Erosion in the shoreface Present day

  6. Existing sand management plan Priority sites CPER 2007/2013 Narbonnais Accretion Erosion 1984/2009 The Coastal Sand Management Plan of Languedoc-Roussillon Homogenisation and globalisation of sand management to regional scale (Brunel et al., in prep.)

  7. (BEACON, 2009) The Coastal Sand Management Plan of Languedoc-Roussillon (Patsch & Griggs, 2007)

  8. The Coastal Sand Management Plan of Languedoc-Roussillon Restoration of global sand transfer

  9. Conclusion
