Abstract: The micromodel is an extremely small physical river model having a movable bed, varying discharge, and numerous innovations to achieve quick answers to river engineering problems. In addition to its size being as small as

Abstract: A model is developed for estimating the applied power of a tow as a function of tow speed through water, tow size, tow integration, local depth, channel size, and whether the towboat has Kort nozzles or open wheel propellers. ...

Abstract: Flow‐resistance coefficients are essential in determining both water‐surface elevations and velocities that are used in many aspects of channel design. Channel boundaries requiring scour protection are often armored wifn ...

Abstract: Minimum bed elevation in stabilized bendways is needed in the design of bank protection. Two empirical methods have been identified for scour-depth estimation that are consistent with available resources on a typical ...

Abstract: A design procedure for sizing gabion mattresses is presented that is based on depth-averaged velocity in the same manner as the Corps of Engineers' 1991 riprap-design guidance. This allows variation of gabion-mattress rock ...

Abstract: A design procedure for overflow spillway crests, which is applicable to a wide range of approach depths, upstream slopes, and heads on the crest, is developed. An earlier crest design procedure is used to proportion a ...
