Estudo da influencia das condicoes hidrodinamicas na desestabilização da ponte sobre estuário Chipanca

Abstract

The study had as propose the studying of hydrodynamic condition influences on destabilization of the bridge located over Chipaca river. Therefore, two oceanography surveys were carried out on 25th and 26th of June in recent year of 2017, in order to collect the data referent to the tidal amplitude, sample of water, and current velocities. The data collection it was made during neap tidal, on period from 6 hours up to 18 hours. During the survey, it was made an interview to the population, the users of the channel in order to know which factors contributed for the local erosion. After having obtained results it was checked that the tide, the currents and the anthropology action, act as factors which have caused the destabilization of the bridge. In front of those factors the current in ebb has presented major impact over the channel, causing erosion through the current velocities which were great relatively in ebb, and the observed human action was the removal of stones which protect the bridge.
