Discussion of “Development of Integrated Sediment Rating Curves Using ANNs” by Sharad Kumar Jain
Publisher: American Society of Civil Engineers
Framework for Estimating Uncertainty of ADCP Measurements from a Moving Boat by Standardized Uncertainty Analysis
Publisher: American Society of Civil Engineers
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 ...
Open-Channel Capacity Determination Using Hydraulic Performance Graph
Publisher: American Society of Civil Engineers
Abstract: A method for determining the flow carrying capacity of a channel system, capable of accounting for the interacting backwater effect among channel reaches and incoming lateral flow, is presented here. The method makes use ...
Experimental Demonstration of a New Extension Plate Scour Countermeasure Downstream of Stilling Basins
Publisher: American Society of Civil Engineers
Transitional Flow at Low-Head Ogee Spillway
Publisher: American Society of Civil Engineers
Abstract: Low-head gated spillways provide controlled flow releases for defense against floods and a reliable supply of water for beneficial uses. In addition, a system of spillways in a large water resources system may be used for ...
Fast Approach for Unsteady Flow Routing in Complex River Networks Based on Performance Graphs
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new model for unsteady flow routing through dendritic and looped river networks based on performance graphs. The model builds on the application of a hydraulic performance graph (HPG) to unsteady flow ...
Investigation of Two Elemental Error Sources in Boat-Mounted Acoustic Doppler Current Profiler Measurements by Large Eddy Simulations
Publisher: American Society of Civil Engineers
Abstract: Measurements of water discharge and flow velocities in riverine and tidal environments are commonly made with acoustic Doppler current profilers (ADCPs) mounted on a moving boat. This paper presents results of high-resolution ...
Near-Transducer Errors in ADCP Measurements: Experimental Findings
Publisher: American Society of Civil Engineers
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 ...
Comparison of Two Rating Approaches to Monitor Uncontrolled Culverts’ Flows Driven by Small Head Differences
Publisher: ASCE
Abstract: The smallest flows that can be rated using a distributed-type hydraulic rating, which must rely on head- and tailwater stages monitored at local stilling wells, are limited by the combined measurement uncertainty of the ...
Applications of Computational Fluid Dynamics to Flow Ratings at Prototype Spillways and Weirs. I: Data Generation and Validation
Publisher: American Society of Civil Engineers
