GUERRERO HERRERA, Humberto; SALTOS SANCHEZ, Armando    VARGAS JIMENEZ, Julio. Regeneration and Stabilization of the beach of San Lorenzo of the canton Salinas, province of Santa Elena. []. , 5, 1, pp.9-18. ISSN 1390-7697.  https://doi.org/10.26423/rctu.v5i1.263.

An adequate solution for beach recuperation is the regeneration through hydraulic fill. In the case of San Lorenzo Beach (Salinas, Santa Elena province) we propose to use a sand dredger to extract about 1500 cubic meters of sand from 1.3 to 1.6 nautical miles in open sea. The sandy sediment will be pumped thru floating ducts and placed on the beach confining the sand in geo ducts which will be placed along contour 2,3 according to the syzygy (Mean Low Water Spring MLWS) average. The maximum elevation above MLWS of the fill will include 4.3, 4.5, 4.8 y 4.6m meters which will be above flooding levels. It is anticipated that the beach will have an intertidal zone of 90 meters and a 30 meters horizontal dune at the levels indicated above generating a beach 50 meters long above the tidal wave. This project will be longitudinally about 1500 meters between the Yacht Club and the San Lorenzo Sea Wall that is confined between the front wall of the boardwalk with a width of 121 meters of longitudinal Geotubes protected with Geostakes perpendicular to this alignment.
