1. Tam Hai Island (Vietnam)
​
Plastic pollution is caused by the car industry in Truong Chiang estuary and around Tam Hai Island; the latter lies in the mouth of the estuary. Specifically plastic pollutants are dispersed in the area by a point source in the estuary and in addition, by the two branches of Truong Chiang River, which also carry plastic pollutants:

Considering the hydrodynamic conditions in the area including the ocean tide, and all the given field-data, the Water Quality Model incorporated into the Delft3D Flexible Mesh Suite, was applied for modelling time equal to 14 days, and results are shown in the following video clip:
2. Menidi beach (Greece)
​
A groyne field consisting of 4 groynes is proposed at Menidi beach in Ambracian Gulf to mitigate the adverse impacts of coastal erosion, following the construction of a new breakwater at Menidi Port.

The aforementioned area was modelled via UNIBEST, a shoreline model, and a 10-year prediction of the shoreline evolution was consequently created:
Moreover a 10-year prediction of the 2D seabed evolution was provided regarding the same area via the Delft3D Flexible Mesh Suite:
3. Amarynthos beach (Greece)
​
Amarynthos is a highly regarded touristic area on Euboea Island. A coastal engineering project with respect to this case study was conducted to investigate potential erosion problems due to the scheduled construction of a new leeward breakwater as part of the upgrade of a fishing port nearby:
Fig 3. The red circle denotes the area where the new port elements are going to be constructed: A. the leeward breakwater; B. the wharf; and Γ. the groyne.
Initially, a 2D model of the case study via Delft3D Flexible Mesh Suite was developed to gain insight into the 10-year expected morphodynamic evolution of the area surrounding the port:
​
Then we focused on the area on the west side of the port, where valuable touristic infrastructures exist to ensure the coastline is not going to be eroded. To this end, the UNIBEST shoreline model was applied, and a 10-year shoreline morphodynamic prediction was performed:
After, ensuring that Amarynthos Beach does not face any sort of long-term erosion threats, storm events which could potentially damage the beach were also investigated. Therefore, an 1 hour storm event of wave height: 1,20 m from SE direction was modelled via Xbeach:
