The Catalan Coastal Depression, Catalan: Depressió Litoral Catalana, is a natural depression between the Catalan Pre-Coastal Range and the Mediterranean Sea. It is part of the Catalan Mediterranean System.

Geography

The Catalan Coastal Depression runs roughly in a NE-SW direction along parts of the following comarques: Empordà, Gironès, Selva, Maresme, Vallès, Barcelonès, Baix Llobregat, Penedès, Tarragonès, Baix Camp and Baix Ebre.

The Catalan Coastal Depression is about 300 km long and 20 km wide on average^[1] Some of the main Catalan cities are located in this area.

Ecology

Much of the surface of the Catalan Coastal Depression is subject to severe land degradation, owing mainly to urban sprawl.
