EMS RIVER. ARTIFICIAL FLOODING POTENTIALITIES
Abstract
The hydraulic effects and nature of artificial-flooding potentialities are described for the Ems River basin located in northwest Germany. Data are given regarding (1) the normal and extreme stages and surface velocities at key stations; (2) stream gradients and depths, and channel and flood-plain widths; (3) locations and zero elevations of gaging (pegel) stations; (4) locations and dimensions of navigation structures, levees, and bridges; (5) the extent of flooding which could be created by erection of temporary dams; and (6) the magnitude and duration of flood waves and flow variations which could be created by the destruction or manipulation of stream-control structures and their effects on bridging, crossing, and navigation of the Ems. Still-water barriers such as temporary dams would hinder trafficability by shallow overlook flooding; this would be minimized in the backwater reaches because of low normal stream velocities. However, inundation of the reclaimed marshland adjacent to the tidal reaches by the admission of salt water through the dykes would greatly hinder maneuverability and trafficability over an extensive area. Destruction of the navigation structures (dams and locks) would create flood waves of up to 12-hr duration and would disrupt navigation, eliminate power supplies, damage or destroy downstream dams, create local floods, and disrupt crossing operations.
