Abstract: There are a plethora of analytical methods that can account for the effect of unsteady flow (i.e., hysteretic behavior) on steady-state stage-discharge rating curves (hQRCs) used to continuously estimate discharge in ...

Abstract: This paper presents the findings from a series of flume experiments conducted to determine scale effects in small-scale models of flow around a single spur dike (wing-dam, groyne, or abutment) placed in a channel whose bed ...

Abstract: This paper discusses a full-fledged uncertainty analysis implementation using the Guide to the Expression of Uncertainty in Measurement (GUM) as framework. Currently, there are few examples of rigorous GUM implementations ...

Abstract: A large thermal-power station drawing water from a small alluvial river had a chronic problem with alluvial-bed sediment buildup at the station’s river-water intake structure. The problem required expensive corrective ...

Abstract: In spite of the extensive use of acoustic-Doppler current profilers (ADCP) for measurement of velocity and discharge in open-channel and riverine environments, a rigorous methodology for estimating ADCP discharge measurement ...

Abstract: The writers’ experiments on local scour at vertical cylinders placed in a sand bed show that similitude of large-scale turbulence is an important consideration influencing equilibrium depth of local scour. For the range ...

Abstract: In the last 3 decades, quantitative image velocimetry has considerably grown in popularity in the fluid mechanics research community. More recently, image-based techniques have been extended to hydraulic applications for ...

Abstract: Acoustic Doppler current profilers (ADCPs) are not able to accurately determine velocity near their transducers and near the bed. These limitations have restricted the use of ADCPs to flow depths that are large enough to ...
