Hydraulic Design of Navigation Dams

This manual provides guidance in designing, constructing, and operating navigation dams. Some of the factors affecting the safety and efficiency of waterways that are discussed include: types of dams; environmental considerations; equipment in general use on navigation dams; options of design to accommodate ice/debris passage, emergency operation; normal operation to pass flood flows, removal of sediment, or assistance in hydropower development. Some information is also provided on the repair and rehabilitation of existing structures. Contents:
