Abstract: Formulations for bed armoring and hydraulic sorting of bed sediments in alluvial streams are developed, and an application to Missouri River bed evolution is presented. A relation for the areal coverage factor for armoring ...

Abstract: The future course of bed degradation in the middle Missouri River has been predicted using numerical simulation techniques. The simulation required development of the new Total Load Transport Model (TLTM), which incorporates ...

Abstract: Two-phase flow analysis is used to analyze sediment concentration profiles in uniform open-channel flows over flat, sediment-starved beds that have high concentrations of single-sized sediment. Two-phase flow analysis can ...

Abstract: This is one of several introductory papers resulting from work by the ASCE Task Committee on Irrigation Canal System Hydraulic Modeling. It is intended to serve as background for analyses by the Task Committee of several ...

Abstract: Because of hydraulic sorting (selective transport of grains by the flow), bed‐load transport of mixtures of sand and gravel in streams is difficult to predict. The transported gradation is generally different from the ...

Abstract: Water losses in irrigation systems are a major problem in arid countries. The losses are primarily due to inefficient irrigation systems and uncontrolled water delivery. Improving the irrigation‐management systems is ...

Abstract: A turbulence-based computational procedure was developed for the modeling of depth-averaged, time-dependent flows with recirculation zones and applied to the prediction of flow fields in navigation installations induced ...

Abstract: A new mathematical formulation is established for two‐dimensional (plan view) unsteady water flow, sediment transport, and bed evolution in natural watercourses such as reservoirs, estuaries, and coastal waters, where depth ...
