Abstract

Flooding events accompanied by destruction of human infrastructure many times are related with evolution of river drainage. If towns were built or will be built on or near an abandoned channel it is dangerous because if this channel is the misfit element of a reverse drainage basin, it could change again to its original flow forming a re-established drainage. In this case, the abandoned channel could become active, and in the area of the wind gap large gorges could be formed, with consequent impact on human activities. Also, we can predict that in the next e.g. ?100 years: a) The reverse drainages of Olvios and Rethis rivers, will remain stable, whereas the antecedent drainage of Piros and Selemnos rivers could change to a reverse drainage.
