From the Piedicollo railway, which runs along the left bank, one can see tne characteristic construction of the dams and the intake. The latter consists of a tubular gallery more than 800 metres in length with a diameter of ten metres, forming a roadway over which two motor lorries could easily pass at the same time. This-immense tunnel descends in a slight curve parallel with the river bed, the outlet returning the waters to the river bed further down.
In the stretch included between the beginning of the tunnel and its outlet, the old water course remains dry or covered only with a little stagnant water, and it will therefore be possible to build the enormous dam here. It will, however, be necessary to take certain precautions in view of the fact that the damming of the waters takes place in a very narrow gorge; account must also be taken of the fact that the special characteristics of the Isonzo, namely, its tendency to frequent and unexpected flooding, may render the construction of this important work somewhat dangerous.
An extremely interesting piece of work is, however, being planned: an enormous box of solid reinforced concrete will support a very strong curved dam 35 metres in height and built into the on both banks. The box has been let down into the river bed and affixed to the rocky strata by a unique system of internal excavation by means of compressed air.
