Topography and geology

Doha is located on the central-east portion of Qatar, bordered by the Persian Gulf on its coast. Its elevation is 10 m (33 ft). Doha is highly urbanized. Land reclamation off the coast has added 400 hectares of land and 30 km of coastline. Half of the 22 km of surface area which Hamad International Airport was constructed on was reclaimed land. The geology of Doha is primarily composed of weathered unconformity on the top of the Eocene period Dammam Formation, forming dolomitic limestone.
