The plane waves allow recognizing on the coasts, strips of risks or erosion hazard on the coastlines. The average period between waves recorded on different shores and extended within the Bahia de Panama, was of 18 s, with a wave length estimated of 500 m in deep waters and which was determined by the propagation direction

towards the Bahia de Panama of approximately 205 SSW.  The diagrams of waves show initially diffraction of the waves on the entire western sector, from Punta Mala to Punta Lisa (Azuero Region); and the divergences in Bahia Parita y Panama (zones of reduced energy) and convergence (concentration) from de lines of force, specially in the region, including Playa San Carlos and Punta Chame, where it has been clearly showed discontinuous “erosion” of the shores formation occurred from the past.  Otherwise, to the Eastern Sector behind Archipielago de las Perlas (Isla del Rey), shows reduced energy of the waves. Convergency of the orthogonals on Punta Cocos (Isla del Rey) and Galeta Island. The crests of the waves flow directly on the entire region extending from Cerro Sapo to Bahia Piña.
