Backwater as a hydrological hazard phenomenon has been scarcely studied scientifically, at both national and international levels. For this reason, this study highlights and describes five types of backwater recorded on the Romanian territory, which posed a great danger to population safety. The backwater caused in Romania is due to ice jams, large dams, misplaced dams, or too small bridges, to poorly designed spillways for large waters built on dams, on dikes in the Danube Delta, etc. The most interesting aspect of the study, at the same time, the novelty of it, is the backwater that is caused on the Buhai brook, which rose over the dam of Lake Ezer, spanned the large water spillway, and flooded the lacustrine water body. This type of backwater was named “spider flow.” All types of backwater analyzed in this study were also caused by human activity, mostly by design errors (the backwater on the Buhai brook, within the Danube Delta, on the Suhu River) or by bad flow management (the backwater in the Stanca–Costesti Hydro-Energetical Junction). The backwater formed on the Bistrita River has complex causes—both natural and anthropic, and it only occurs during the winter.
