Abstract : A report is made on an investigation of the hydraulic nature of the artificial-flooding potentialities in the Drau River Basin which covers the main stem of the Drau Rover and its main tributary, the Mur River. The investigation was concerned primarily with (1) the normal and extreme discharges, stages, and velocities at key stations on both rivers; (2) stream characteristics including gradients, depths, and channel and flood-plain widths; (3) locations and zero elevations of gaging stations; (4) locations and dimensions of dams, bridges, and hydroelectric projects; (5) the extent of possible flooding resulting from the erection of temporary dams; and (6) the effects of breaching of or regulated discharges from major dams and reservoirs. The study showed that still-water barriers and drainage obstacles would reduce over land trafficability along the lowered Drau River for extended periods and create some obstacle to river-crossing operations along the lower Mur. Temporary damming of streams and drainage in the Klagenfurt Basin would inundate the marshy area. Combined with the Woerther See, this would present a considerable obstacle to overland traffic and bridging operations near Klagenfur, an important communications center. Breaching power dams at Schwabeck, Lavamuend, Dravograd, Vuzenica, Fala, and Maribor would produce appreciable flow variations along the Drau to the confluence of the Mur as well as seriously affect he electrical power supply of southern Austria and northern Yugoslavia.
