Abstract: The feasibility of pier nose extensions as an environmentally acceptable alternative to reduce local pier scour for a nontypical pier geometry was investigated using a 1:30 Froude-scaled movable-bed model. The movable-bed ...

Abstract: The development and implementation of a stabilized finite-element model for the simulation of large-scale geophysical flows using the shallow water equations (SWEs) is presented. The model is derived from the mass and ...

Abstract: Complex interactions between flowing water and bedforms in rivers with sand beds during changing flow rates may result in bedforms, flow resistance, and sediment transport rates that differ on the rising and falling limbs ...

Abstract: Natural rivers and streams are influenced by runoff from rainfall and snowmelt, resulting in flow conditions that change over timescales that are related to the size and location of contributing watersheds. Predictive ...

Abstract: This technical paper presents the development and application of a pseudo-transient continuation (PTC)– inspired flow model for the simulation of dam and levee failure. The unstructured, implicit, Petrov-Galerkin finite-element ...

Abstract: Bed-load transport is an important process impacting riverine morphology, but until recently it has proven difficult to measure in large sand-bed rivers. Integrated Section, Surface Difference Over Time, version 2 (ISSDOTv2) ...

Abstract: Quantification of sediment transport rates is necessary for river management but remains difficult due to large volumes of sediment in motion, spatiotemporal heterogeneity in discharge, depth, and morphology, the need for ...

Abstract: The Integrated, Section Surface Difference Over Time, version 2 (ISSDOTv2) method provides a means of quantifying bedload in large sandbed rivers. Like all measurements, it is important to understand the uncertainty ...
