The change of the coastline in the southern part of the province of Alicante for the last 15,000 years have been modeled and described in the work of Tent-Manclus (2013). It is obtained by integrating data from different sources and especially high-resolution seismic profiles of the nearby marine continental shelf. Ten periods have been distinguished in the evolution of the Bajo Segura coastline : 1) 15000 BP- 14600 BP: rapid rise; 2) 14600 BP to 13500 BP: the Older Dryas, slow rise; 3) 13500 BP to 12700 BP: stability and descent; 4) 12700 BP to 11700 BP: the Younger Dryas, descent of the sea ​​level; 5) 11700 BP to 11300 BP: very fast rise; 6) 11300 BP a 8500 BP: rapid rise; 7) 8500 BP = 6500 AC to 8200 BP = 6200 AC: 8.2 ka event stabilization; 8) 6,200 BC to 4,000 BC: rise,  Tabarca Island is form; 9) 4000 BC to 3000 BC: the slow rise due to subsidence sinus ilicitanus forms and 10) 3000 BC to the present day 2000 AD: the sinus ilicitanus desiccates.

Maps at different times are show selected from the 164 maps that have been made. This is a first version of how the coastline evolves in the region. This work It can be a starting point to improve knowledge of the historical landscape evolution..

The sinus ilicitanus  dries until today, the rest of which are the lagoons of the Fondo and Santa Polo Salinas.
