In order to determine the different characteristics of piers, they can be classified according to their location:

• Sea
• River
• Dam/Reservoir

Or according to their use:

• Sports piers: kayaking, canoeing, sailing, etc.
• Tourist leisure activity piers.
• Traditional piers for sailing boats and motorboats.

‘Ebro’-type river piers

This model was designed especially to cope with strong currents and variable water levels.

Allows negative slopes to cope with exceptionally high water levels.

In the photograph below you can see how the pier behaves when there are high water levels.

General characteristics:

• Variation in the water level: up to ±4.5m.
• Maximum current speed: 3m/second.
• Hydraulic pressure: 4.5kg/m2.
• Maximum wind speed: 100km/h.

River pier with piles:

• Variation in the water level: up to ±4.5m.
• Maximum current speed: 3m/second.
• Hydraulic pressure: 4.5kg/m2.
• Maximum wind speed: 100km/h.
