This is not a post, this is a call: a call for help.

Long time ago I thought about modelling the Venice lagoon in a different way. You know, there are already many kinds of models, conceived for a better knowledge of this lagoon phenomenology:

- the physical ones, like the big one in Voltabarozzo, Padova (Italy) that reproduce the whole area (550 kmÂ²) with a planar geometric factor of 1:250

- the many numerical models, of all types (finite differences, finite elements, finite volumes
*et coetera*…), that aim to reproduce the many different aspects of such a complex hydraulic, hydrodynamic, morphologic, biologic quest… or, in fewer words, of such a huge environmental problem.

The second ones bloomed and I can’t make a list of the models realised so far, even if I’ve seen some of them.

Waiting for an SPH model of the lagoon (see my SPH experiments), we still must deal with the imperfect reality of modelization.

If we limit our analysis in the hydraulic domain, it simplifies accordingly letting us consider the whole complex as a non-trivial ensemble of flows, resistances, reservoirs.

The main boundary condition of this problem is the tidal one, a sinusoidal signal (composed of more than one harmonic, but quite simple) superposed with a meteorological component which depends basically on winds and macro-scale pressure fields (two aspects of the same *phenomenon*).

All this made me think about the study of circuits under alternate current, which are, as well, systems forced with an external oscillating potential difference: this was sometimes done, in the past, via a hydraulic analogy for electric current.

Why not to build, reversing this theory, an electrical model of the Venice lagoon? The lagoon itself is a big capacitor (or sum of capacitors), the channels are components with (non-linear) resistive-like behaviour and inertia can be *translated* with right inductance distribution, even if turbulence effects could take more time to be reproduced. The results I expect are not much better than the numerical models output but it could be very interesting to conduct such an experiment, and most of all one could have a real-time tool for water level prediction, without wasting teraflops and teraflops for this simple result.

I have not materials and electro-technical preparation, but I’m sure matlab and similar tools can give all one could need for a *numerical* model of the *analogical *model of the Venice lagoon!

Can anyone help me in finding the right informatic stuff needed for a preliminary study *in silicium*?
