ROSES MARITIME FRONT COMPETITION

Beach Dynamics

The wave propagation in the Gulf of Roses refracts according to the depth of the coastal relief. This wave refraction reaches the breakwater, which blocks the outflow of the Ginjolers stream into the sea and causes a reflection that produces a sudden change in currents at this point. This reflection causes a bend in the coastline between breakwaters with a transverse transport of sand.

To correct this phenomenon, it would be necessary to avoid the generation of waves caused by the reflection of waves on the current breakwater.
Since constructing a submerged breakwater perpendicular to the main wave direction that would cause the wave to break before reaching the breakwater would involve unnecessary investment costs for a new submerged breakwater and sand dredging for beach replenishment, we propose creating an immobile artificial beach in the indicated area facing the generated currents. In this way, the sand of the natural beach to be protected both currently and in the future is consolidated.

Burial of the Roadway and Parking

The proposal involves the complete burial of the parking area and partial burial of the vehicular roadway in the space currently occupied by a surface public parking lot. To ensure proper structural strength and watertightness of this underground facility, below the marine water table, a solution involving a reinforced concrete perimeter diaphragm wall is proposed.

A Large Two-Level Promenade

The general organization of the promenade space is planned as the combination of three consecutive strips:

A first upper level adjacent to the buildings on the seafront. This space is partially freed from vehicle traffic and parking, which will be buried, and will be dedicated to civic activities and community events.

A second level situated 50 cm below the first, which will have a more landscaped character and will be intended for leisure activities.

The beach area, consolidated as a natural environment and complemented by a newly created artificial concrete beach treated and adapted to the environment.

Projection of Plaça Sant Pere Towards the Sea

We propose opening the Plaça Sant Pere space towards the sea, once the current barrier formed by vehicular traffic is removed. The existing traditional trees will be preserved, and the public space will be extended to the water’s edge, creating a large platform resting on the water surface and serving as a connecting element between the two beaches.
