waterway

An early work in the French literature of hydraulic engineering. In the preface, Bouillet states that some of the machines he proposes were used in Holland and that some of his descriptions are translations of the Dutch. He describes methods of dredging rivers, constructing slipways and sluices, clearing ports and harbors, and maintaining river banks. He also discusses two techniques of raising a sunken ship and a way of blowing the deck of a ship with gunpowder to reveal cargo and then, salvaging it with diving bells made of copper.
