Project description:

The tourist craft is located in Kiparissi cove at Laconia. The immediate area of influence is composed of two distinct parts of the coastal zone. The first section is located on the southern shores at “Paralia”. The second part is located on the north shore at “Agios Nikolaos”. In coastal engineering study investigated the coastal phenomena, such as sediment’s deposits and erosions before and after the construction of the proposed 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 analysis: seabed sediment data collection, laboratory analysis for determining the composition of the sediment particle size and other physical and statistical parameters (e.g., average diameter, standard deviation, etc).
  • 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 (CERC) and numerical models (SBEACH).
