Abstract
In the current study, the investigation of the torrential potential of the \“Gouras”
stream in the region of Epirus (W. Greece) showed that this is affected by four
basic torrential factors: climate, rocks, relief and vegetation. Conditions of
mudflow are determined by the torrential potential. In other words, big mean
slope of watershed, large quantities of debris, erosive geological layers, intense
relief, heavy rainfalls, numerous places which produced sediment yield etc
appear in its environment, something that derives also from the presence of a
great landslide in the upper part of its watershed. Finally, the research of the
mechanism and movement conditions of the concrete mudflow ends with the
presentation of the appropriate management system and the relevant technical
works that should be applied.
Keywords: torrential phenomena, landslides, mudflow, management system.
1 Introduction
Hydrology distinguishes the water currents into four categories: big rivers,
rivers, torrential rivers and torrents. Torrents are characterized by the following
properties:
−Sudden and intensive floods of small duration appear in the winter, while
there are small or no supplies during the rest of the year
−Debris materials (especially gravel matters) are extracted, transported and
deposited in their action zone.
Mud streams are torrents of mountainous areas characterized by an intense and
massive transportation (mud flow) of very gravel matters and an irregular water
balance.
Keywords
torrential phenomena, landslides, mudflow, management system.
