Requirements and availability of sand for the protection of Nechochea and Lobería beaches

Mostrar todas las versiones(3)

The coast of Lobería and Necochea is characterized by cliffsand narrow beaches. The inlet of the Quequén Grande river used to alter the coastline. The construction of jetties related to the Quequén Harbour induced huge accumulations of sand towards Necochea, and a critic erosive process of cliff and...
