Abstract: | The annual hydrological cycle of the Caimanero-Huizache lagoon system on the Pacific coast of Mexico was investigated during 1977–1978. There is a well defined wet season during which the lagoons fill with water derived from fluvial inputs and direct precipitation. Water is lost by evaporation and outflow to the sea, the latter process starting as the wet season progresses and being facilitated by a falling mean sea level. Evaporation exceeds in situ precipitation and during the dry season complete desiccation may be prevented by a now rising mean sea level which promotes the flow of seawater into the lagoon basin. A quantitative estimate of the magnitude of these controlling processes is presented and processes bringing about mixing in the lagoons discussed. A brief comparison is made with other lagoon systems on the Pacific coast of Mexico. |
