The river is embanked and is crossed by the Pont Doumer, a fine railway bridge over i m.
In dams of moderate height above ground and considerable depth below ground there is, moreover, no reason why advantage should not be taken of the earth resistance due either to the downstream face of the trench against which the foundations are built, or to the materials excavated and properly embanked against that face above the ground level or to both.
We do not always know the least resistance which it is safe to give to a retaining wall subject to the pressure of earth, or conversely, the maximum resistance to side-thrust which natural or embanked earth will afford, because we wisely neglect the important but very variable element of adhesion between the particles.
The river is embanked from Piacenza, and continuously from Cremona, the total length of the embankments exceeding 600 m.
Harbour front runs the Paseo (Alameda) de Paula (1 77 2 - 1 775, improved 1844-1845), an embanked drive, continued by the Paseo de Rocali and the Cortina de Valdes, with fine views of the forts and the harbour.
