Analysis of the Effect of Tidal Level on the Discharge Capacity of Two Urban Rivers Using Bidimensional Numerical Modelling

This article quantifies the variation of the discharge capacity of an urban river of the Galicia region due to the tidal level at the river discharge. During high tides, the water level on the river outlet produces a backwater effects that reduces the maximum discharge. This results in a decrease of the maximum capacity to one third of the maximum discharge during low tide.
