Project description:

Kalo Chorio is located on the northern coast of Eastern Crete. The coastline in the wider coastal zone is rocky. Near the area that proposed to construct the fishing shelter there is a sandy beach. 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, c) ocean study by the university of athens
  • 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).
