During the pope's absence in Paris, at the coronation of Napoleon, Consalvi remained as virtual sovereign in Rome; and his regency was rendered remarkable by a great inundation, caused by the overflow of the Tiber, during which he exposed himself with heroic humanity for the preservation of the sufferers.
The waterways of Cochin-China communicate by means of natural or artificial channels (arroyos), facilitating transport and aiding in the uniform distribution of the inundation to which the country owes its fertility.
The lowlands of Tilsit are protected against inundation by dikes.
A portion of the stream of the Drin has found its way into the Boyana channel; the result has been a rise in the level of Lake Scutari and the inundation of the adjacent lowlands.
On the west the shore is perfectly flat, so that a slight rise in the water causes the inundation of a considerable area - a fact not without its influence on the estimates made at varying periods as to the size of the lake.
