Major changes in the watershed
During the next centuries the estuary of this new river—the Soča—moved eastward until it captured the short coastal Sdobba River, through which the Isonzo now discharges into the Adriatic Sea. The former estuary (of the Aesontius, and the early Isonzo) in the newly formed lagoon of Grado became an independent coastal rivulet.
