Resumo
The Eastern coast of the Granada Province, modelled on Alpujarrides metapelitic rocks, has been very frequently affected by landslides, usually triggered by a combination of rainfall and anthropic actions. Its relief includes instable zones and old landslides of variable size and unknown age. In the seventies, great residential resorts were damaged in Punta de la Mona and Velilla (Almuñécar), and then roadworks for widening the National Road 340, induced slope failures affecting new residential areas along the road in the municipalities of Salobreña and Almuñécar. More recently, from the late nineties, a great residential complex built up on Cerro Gordo (La Herradura, Almuñécar), is heavily affected since 2005 by widespread damages; its construction involved excavations and fillings, frequently performed too quickly, and lacking of adequate drainage and stabilization treatments. Rainfall and the leaks by breakage of water supply and sanitation networks are the main triggering factor. In this paper the main geological and geotechnical features common to the different study cases are described and also some relevant aspects of a final legal sentence which concern to the urban planning and the geotechnical practices and should be taken into account in order to minimize its undesirable consequences.
