Orhtological Management of Hydrological Runoff Basins of the Prefecture of Drama (Current Situation - Protective Actions - Perspectives)

This paper presents the torrential environment of the torrents of the area of the prefecture of Drama. Firstly, the torrents of the area and their morphometrical and hydrological characteristics are imprinted. At the same time, the torrential environment (potential) is specified with the analysis of the basic torrential factors (climate, relief, geological base, vegetation). After that takes place the calculation of the maximum expected water discharge and sedimentary flow with the use of empiric and analytical types. The constructive and operational characteristics of the most important hydrological constructions of the area are synoptically described. According to these data, the present situation is defined, the water potential of the area is evaluated and some further solutions are proposed for the best possible utilization of the water environment. These data were gathered and digitized in a geographical database.
