The fundamental and ultimate reason for beach erosion is development of quick sand condition by various natural and artificail reasons. In some cases, the quick sand condition can be prevented by nullyfying the effect of permeated seawater into beach sand. A perforated pipeline along the beach is buried to collect this percolated seawater and allowed to move by gravity in this pipeline to a lower elevation. This collected water is then pumped out to a safer place. There are various practical conditions to be considered for implementing this concept in the field.
