Over the past two decades the application of acoustics to the measurement of small-scale
sediment processes has been gaining increasing acceptance within the sedimentological …

Water quality control and management in water resources are important for providing clean
and safe water to the public. Due to their large area, collection, analysis, and management …

A new method for detecting spikes in acoustic Doppler velocimeter data sequences is
suggested. The method combines three concepts:(1) that differentiation enhances the high …

To date, flow through submerged aquatic vegetation has largely been viewed as perturbed
boundary layer flow, with vegetative drag treated as an extension of bed drag. However …

Field measurements of turbulence are presented from two sites in Puget Sound, WA, that are
proposed for electrical power generation using tidal current turbines. Time series data from …

Bed stresses in the bottom boundary layer of the York River estuary, Va., were estimated
from 3D near-bottom velocities measured by Acoustic Doppler Velocimeters (ADVs) and …

A laboratory experiment was performed to study the dynamically rich interaction of a
turbulent open channel flow with a bed-mounted axial-flow hydrokinetic turbine. An acoustic …

In contrast to free shear layers, which grow continuously downstream, shear layers
generated by submerged vegetation grow only to a finite thickness. Because these shear …

Understanding the flow field around horizontal axis marine current turbines is important if
this new energy generation technology is to advance. The aim of this work is to identify and …

Bed shear stress is a fundamental variable in river studies to link flow conditions to sediment
transport. It is, however, difficult to estimate this variable accurately, particularly in complex …
