THE CONTRIBUTION OF THE MORPHOMETRIC PARAMETERS OF AN HYDROGRAPHIC NETWORK TO THE INVESTIGATION OF THE NEOTECTONIC ACTIVITY: AN APPLICATION TO THE UPPER ACHELOOS RIVER.

In this paper the relationship between the morphometric parameters of a drainage system and the neotectonic activity is investigated. The hydrographie network of the Upper Acheloos River was chosen as the study area. The whole network and especially its western-southwestern part appears to be in the rejuvenated stage of evolution, as it is concluded by the analysis of the parameters, associated with the shape and slope of the basins, and the slope of the respective streams. Furthermore, the shape of the drainage network and the structure of the basins suggest that not only the Alpine orogenesis but also the neotectonic activity controls the morphogenetic processes in the are
