Study of the dynamic behaviour of the Sancti Petri Channel, southwest coast of Spain

The dynamic behaviour of the Sancti Petri tidal channel (southwest coast of Spain), which is open at both ends and connected to water bodies with different dynamic characteristics (Atlantic Ocean and Cádiz Bay), is studied herein. This singular estuary is characterized by double inflow-outflow extre...

This singular estuary is characterized by double inflow-outflow extremes, the tide penetrating almost simultaneously through both ends with a small difference of amplitude. For this study, sea level recordings were obtained from different points throughout the channel and the corresponding harmonic constituents were determined. The results show that the phases of the semidiurnal tides increase from the mouths to a zone located in the vicinity of the channel´ s halfway point, while their amplitudes increase from the Atlantic Ocean to Cádiz Bay along the channel. A one-dimensional numerical model with geometry that is representative of the channel was used to reproduce the features observed for the semidiurnal and diurnal tidal constituents. The data supplied by the model were verified with values obtained at strategically chosen sites of the inner domain. The model developed may be used for operational predictions of tides in the study area, especially for the ports of Gallineras and Sancti Petri. El canal de marea de Sancti Petri se sitúa en el suroeste de las costas españolas y se encuentra conectado a dos cuerpos de agua con características dinámicas propias (Océano Atlántico y Bahía de Cádiz) a través de sus dos extremos. Es éste un singular estuario, por cuanto la propagación de la marea se produce, casi simultáneamente, desde sus dos desembocaduras, con una pequeña diferencia de amplitud. A partir de los datos experimentales se observa que las amplitudes de las constituyentes semidiurnas aumentan a lo largo del canal desde el extremo más al sur (Océano Atlántico) hasta el extremo que conecta con la Bahía de Cádiz, mientras que las fases de estas constituyentes presentan un máximo en una zona próxima al punto intermedio del canal. A partir de un modelo numérico unidimensional, se estudió la propagación de las principales constituyentes semidiurnas y diurnas de la marea. Los resultados obtenidos mediante los modelos han sido validados con datos experimentales tomados en puntos estratégicos dentro del canal. El modelo desarrollado puede ser utilizado para obtener predicciones de mareas en la zona de estudio, especialmente en los puertos de Gallineras y Sancti Petri.
