Abstract

Catastrophic effects in the Aras gully's flood exceptionally intense rainfall and the great contribution of solids to riverbed, proceed from hillsides very erosives. This article calculates possible flows from different hypothesis and analyses geomorphologic characteristics of the catchment area, especially detritus deposits operated as source area of the sediments transported along the gully. Besides natural operation processes, the anthrophic actions deterrnined in the management of the environment have contributed to the origination of catastrophe of with an enormous magnitud.
