Navigability of the river Ebro below the stone bridge in Zaragoza


Expo Zaragoza 2008, S.A.
Technical studies and design

The aim of the studies was to determine the works necessary to ensure navigability of the River Ebro under the Stone Bridge in Zaragoza. A detailed hydraulic modelling was made dividing the channel into 6 channels corresponding to the arches of the bridge. To do this, a model was developed that calculates the transit of a wave by means of an explicit integration of the Saint-Venant equations using the equation of conservation of quantity of motion assuming that the pressure of the water on a profile coincides with the hydrostatic pressure.
