Abstract : The hydraulic effects and artificial-flooding potentialities are described for the Aller and Leine rivers located in the Weser River basin of northwest Germany. The Leine is a 279-km-long tributary of the Aller which is a 263-km-long tributary of the Weser. Considerations are confined to the main stem of the Aller, the Leine area below the confluence of the Rhume River, and the reaches of the Rhume, Oder, and Soese Rivers below the Oder and Soese dams. Data are included for: (1) the normal and extreme stages and surface velocities of key stations; (2) stream gradients and depths, and channel and flood-plain widths; (3) locations and zero elevations of gaging stations; (4) locations and dimensions of navigation structures, reservoirs, and bridges; (5) the extent of flooding possible by the erection of temporary dams; and (6) the magnitude and duration of flood waves or flow variations created by breaching or regulating the discharge of valley and navigation dams, and the effects of waves and variations on the bridging, crossing, and navigation of the rivers. The study showed that the erection of still-water barriers such as artificial dams would hinder maneuverability and trafficability out to about 2 km from the river banks of both rivers. Breaching the Oder, Soese, or Ecker dams would create flood conditions which would damage or destroy bridges and dams for an undetermined distance downstream. The destruction of the large Hartz dams would seriously disrupt the municipal water and electrical supplies to such places as Bremen and Hildesheim.
