Simplified hydrodynamic model for identifying the areas of influence of sub-networks of tidal channels

The model describes the hydrodynamic flow field in an intertidal area by suitably simplifying the shallow-water equations by equating the gradients of the water surface to the (linearized) friction terms. The product is a poisson-like equation, which uses the position of the channel network as a boundary condition to compute a representative water elevation field. This field allows the computation of flow directions and velocities, together with the values of the bottom shear stress.

This tool can be used to map the areas of pertinence of relevant sub-network of tidal channels of interest, and to relate different channel morphologies to the properties of the pertinence area identified. Local authorities in Venice have expressed interest in the tool to obtain characterizations of areas within the Venice Lagoon.
