KOKKINOS PYRGOS COAST
Comparison between Dossier de Candidature M2.1
and work done until now.

• OK Bibliographical investigation of numerical
  models.

• Face A Application de nouvelles methodes pour
  le suivi de l erosion et rechargement cotier.

• Face B Indentification des plages en erosion en
  Creteet des lieux d accumulation de sable,
  optimisation du sediment disponible, creation de
  modeles numeriques (propagation d onde, courants
  par onde, transport de sediment quasi 3D,
  evolution du lit).

• OK Application of Als (Hs contours, current
  velocities), beach processes understanding.

• Face C Application des modeles numeriques pour
  estimer les taux derosion et deposition,
  levolution du profil apres le rechargement a
  propos du transport offshore, levolution de la
  plateforme et ligne de rivage a propos del
  mouvemants lateraux.

• OK Solutions testing with beach nourishment and
  brakewaters.

KOKKINOS PYRGOS COAST
Solution 1 - Coast evolution trend (sequence of
S, SW and W waves)

• Erosion control with accretion in the area of the
  structures.
• But erosion trend at about 500m east from the
  port.

Other combinations of solutions are running
CONCLUSIONS

• West winds are prevail.

• Possible construction in the future of big trade
  port in the area.

• It is possible to examine various scenarios
  concerning construction of coastal structures and
  beach nourishment.

• The sand for the nourishment will be taken from
  the accretion areas.

• More combinations of submerged breakwaters will
  be tested.
