Abstract: In frequently monitored fluvial systems, such as the middle Mississippi River, large databases of hundreds of cross-section surveys are often needed for assessment of long-term morphologic change and contributing hydraulic ...

Abstract: Articulated concrete block (ACB) revetment systems are widely used for channel lining and embankment protection. Current approaches for prediction of ACB system stability use a moment stability analysis with a ratio of the ...

Abstract: A full-prototype physical model was laboratory tested to determine a rating equation applicable to large Parshall flumes with supercritical flow. The experimental program was composed of a 1.5-m (5-ft.) Parshall flume ...

Abstract: A moment stability analysis method which computes a safety factor using shear stress and flow velocity was previously developed for assessing the stability of articulated concrete block (ACB) systems during overtopping ...

Abstract: A new elliptical sharp-crested weir was developed to address discharge, pollution, and maintenance concerns associated with detention ponds. The elliptical weir was specifically designed to decrease the time and cost ...

Abstract: An elliptical sharp-crested weir design was developed for detention pond outlets to address discharge, pollution, and maintenance concerns. The weir was designed in an effort to efficiently pass debris through an outlet ...

Abstract: Sedimentation processes in reservoirs can jeopardize their functionality and compromise dam safety. Climate change and associated hydrologic uncertainty are introducing additional stressors to US reservoirs, and data-driven ...

Abstract: Several reservoirs across the United States are filling with sediment, which jeopardizes their functionality and increases maintenance costs. USACE developed the Reservoir Sedimentation Information (RSI) system to assess ...
