Abstract

This report presents the results from a meteorological and sedimentological study, of the gulf of Morrosquillo during the dry, season (February/93), where the speed and direction of the wind acted as determinant factors in the circulation of the waters, which was defined from the following parameters: Distribution of the (haline) and thermal fields, transit of the sediment deposited on the surface of the marine botton, horizontal and vertical repartition of turbidity, determined on samples and gauging and analysis of a SPOT satellite image. The morphologic analysis through the comparison of the coastal line images and aereal photographies from differents years, allowedto establish the principal coastal morphologic variations in these zones. The effect of difraction and refraction of the surf front the punta San Bernardo and the compensation arriving to the Mestizos arrow, and the flow originated by the winds produces two principal currents: One in direction south-east starting from punta San Bernardo, that is displaced toward the east of the Gulf and the other east skirting the coast south and south-east. The principal morphological changes of the coastal line were introduced in the south sector of the Gulf. As result of the process of sedimentary acretion originated starting 1938 the delta of the Sinú river as its discharge in the Tinajones zone, evolution that continues. The erosive phenomen on has affected considerably the body of the Mestizos arrow, the marine terrace east of the spike and the sector of beaches between Coveñas and Tolú.
