1 INSTITUTE OF APPLIED & COMPUTATIONAL MATHEMATICS FOUNDATION OF RESEARCH AND TECHNOLOGY CRETE-HELLAS CONTRIBUTION OF IACM/FORTH IN PHASE C OF MEASURE Kokkinos Pyrgos shoreline evolution trend - Research solutions Al. Pantazis N. A. Kampanis Th. V. Karambas

2 KOKKINOS PYRGOS COAST Comparison between Dossier de Candidature M2.1 and work done until now.  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).”  Face C: “Application des modeles numeriques pour estimer les taux d’erosion et deposition, l’evolution du profil apres le rechargement a propos du transport offshore, l’evolution de la plateforme et ligne de rivage a propos del mouvemants lateraux.” OK Bibliographical investigation of numerical models. OK Application of Als (Hs contours, current velocities), beach processes understanding. OK Solutions testing with beach nourishment and brakewaters.

3 KOKKINOS PYRGOS COAST N Current status: Wave induced current velocities for West direction winds.

4 KOKKINOS PYRGOS COAST Current status - Coast evolution trend (sequence of S, SW and W waves) Initial coastline Evolution trend N  S and SW windsAccretion in the bottom of the jetties  W windsErosion 1km east from lee jetty (S and SW windsNW currents) (W windsSE currents)

5 KOKKINOS PYRGOS COAST Solutions under investigation  Beach nourishment with submerged breakwaters

6 KOKKINOS PYRGOS COAST Hs contours for South direction winds  Wave propagation behind breakwaters and partial reflection

7 KOKKINOS PYRGOS COAST N Wave induced current velocities for South direction winds with the submerged breakwaters.

8 KOKKINOS PYRGOS COAST N Wave induced current velocities for South - West direction winds with the submerged breakwaters.

9 KOKKINOS PYRGOS COAST N Wave induced current velocities for West direction winds with the submerged breakwaters.

10 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. Initial coastline Evolution trend N

11 KOKKINOS PYRGOS COAST Other combinations of solutions are running CONCLUSIONS  West winds are prevail.  It is possible to examine various scenarios concerning construction of coastal structures and beach nourishment.  Possible construction in the future of big trade port in the area.  More combinations of submerged breakwaters will be tested.  The sand for the nourishment will be taken from the accretion areas.
