Force and Pressure Measurements in Spillway Plunge Pools
Plunge pools are often used to dissipate energy from high head spillways with flip bucket terminal structures. Conventional design of plunge pools has been based on a program of mobile...
At-A-Site Mountain River Flow Resistance Variation
At-a-site variation in flow resistance is examined in the light of observations of an S-shaped velocity profile at relative submergences (d/D84)...
Evaluating Flow Resistance Using Height of Roughness Protrusions
On the basis of field measurements on the Sumava mountain rivers heights of roughness protrusions have been used for calculation of flow resistance. The result resistance equations, compared...
Flow Resistance of High-Gradient Gravel Channels
The flow resistance in terms of the friction factor for bank-full or high in-bank flows for 120 high-gradient gravel-bed rivers are examined. The friction factor f was divided into grain...
Bed Load Roughness in Supercritical Flow
A supercritical concrete channel has been proposed for Mission Creek located in Santa Barbara County, California. The proposed channel could transport gravels and cobbles as bed load during...
Fluvial Hydraulics of Streams and Mountain Rivers with Mobile Bed
The local hydraulic conditions concerning the incipient motion of the bed material in mountain streams are considered. Results of measurements carried out by using the radioisotope tracer...
Effects of Particle Shape on Bedload Transport
The effects of particle shape on bedload transport in gravel-bed streams are examined using a similarity approach and fractional transport analysis for data from Piceance Creek, Colorado,...
Bed Load Prediction in Steep Mountain Rivers
The characteristics of the stream channel morphologies in a very steep mountain ravine are explained by the data obtained through the longterm field observation. The bed load transportation...
Step-Pool Streams: An Adjustment to Maximum Flow Resistance
An experiment was conducted to study the maximum flow resistance of step pool streams and the morphology of the steps formed from clastic materials. The step pool formation was qualitatively...
Particle Dynamics and Bed Level Adjustments in a Mountain Stream
The focus of the study was the interaction of coarse bedload sheets with a near-static bed. At a critical discharge bed sediment was transported from upstream sources through the study...
Sediment Transport in Sewers and Design Implications
Extended studies on sediment transport in sewers were conducted at the University of Newcastle upon Tyne and using this new as well as previously available data an attempt has been made...
Stochastic Control With Bounded Sample Paths: An Application to Reservoir Systems
The consideration of at least the first two statistical moments for the storage volumes of a reservoir system is crucial in an analysis aimed at determining the optimal operations policies...
Scour Hole Depth Downstream of the SAF stilling Basin
A Model to predict the maximum local scour depth downstream of the SAF stilling basin is presented. The model is based on stability analysis of a particle attacked by the hydrodynamic...
Sediment Transport Analysis Rio Grande Floodway at San Marcial Gauge
A detailed analysis of sediment transport data collected on Rio Grande Floodway at San Marcial gauge shows that the all-year total load rating curve and the seasonal rating curves yield...
Performance of Submerged Vanes for Control of Sediment in an Irrigation Canal
Removal of accumulated sediments from irrigation canals is necessary in order to maintain canal capacity. Removal of these sediments may be enhanced by directing and concentrating sediments...
Non-Point Pollution Loadings and their Impacts on Tennessee Valley Reservoirs
This is a three-year study which began in March 1992. The project has focused on inflow streams entering storage projects including Douglas, Cherokee, South Holston, Watauga, Norris, Chatuge,...
Investigation of an Anisotropic k-? Model
In this paper the eddy viscosity hypothesis is abandoned and explicit expressions of Reynolds stress are deduced directly from the transport equations. Anisotropic k and ? equations are...

A Thousand Points of Data
Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential...
