Project description:

The fishing shelter, located in the East coast of the argolic Gulf, in the Peloponnese. Bounded on the North by the Cape of Trikeri and southward from Cape Lygaria. In coastal engineering study examined the possibility of sediment deposit or erosions in the adjacent beach and the neighbouring shores, as well as the sediment movement in relation to the harbour works.

The coastal engineering study included the following:

  • Data collection: a) climatic data of the region (e.g. rainwater run-off and according data, etc) in order to calculate the wave climate in the deep water, b) aerial photos of different years for the analysis of the evolution of the coastline,
  • Numerical modeling: Waves’ transformation from deep water to the coastal zone taking into account refraction, defraction and waves’ breaking.
  • Sediment’s Recognition: seabed sediments collection
  • Sediment transport: Calculation of longshore and crosshore sediment tranport, taking into account the results of waves’ simulation, the analyses of sediments, the streams and rivers, the sea currents, the tides and the coastline’s changes in previous years on the basis of aerial photographs. The calculation of sediment transport was by using empirical models (CERC) and the beach profile after the works’ construnction with Pelnard-Considere’s method.
