The Archaeological Site of Panama Viejo (Panama) comprises a protected area of 28 km ² within present‐day Panama City, on America's Pacific coast. In 1519, the Spaniards founded the city of Panama Viejo to secure a natural port in an area inhabited by indigenous peoples since at least the eighth century CE. The site, along the coastline and between...

Abstract: Feeding mechanisms for the nearshore, beach and dune systems are significantly linked to fluvial input in the Mediterranean. The erosion of the coast is currently a serious environmental and economic challenge to which the Administration has not only not found an optimal solution beyond costly direct beach fill measures. To investigate wh...

This paper discusses how the beaches of Marbella, on the southwestern Mediterranean coast of Spain, may no longer stay in their natural resilience envelope due to a critically delicate natural sediment transport balance and a degree of artificialization that has entered the whole sedimentary system into a new resilience state. The combination of vi...

It is generally agreed that a falling sea level regime is required in the long term to establish dunes as distinctive landform features along a coast. Sedimentary (supply) bodies from fluvial, glacial sources or marine platform processes also need to be in place. In most Atlantic-facing coastal dune systems the current morpho-sedimentary structures...
