Evaluation of Flow Resistance in Ice-Covered Channels

Scour Protection in Bottomless Culverts
This paper will describe the relative severity of scour anticipated to occur at bottomless culverts and will provide some design guidance for scour protection based on research referenced...

Pollutant Transport Across Porous Stream Beds
The presence of porous streambeds generates a significant interaction between the main stream flow above it and the flow through the porous sub-stratum. This coupling affects both flows,...

Scour Study for Bridge Design on Temecula Creek
Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential...

Synchronized Measurements of Bed-Shear Stress and Flow Velocity in Open Channels with Simulated Vegetation
Synchronized measurements of shear stresses at the bed and velocities both within and above a simulated plant canopy in an open-channel flow are presented. Traditional (hot-film sensors)...

Operational Aspects of Warning
Uzbekistan is referred to as the region where the most dangerous natural phenomena are: mudfloods, floods, and avalanches. During the last decades the areas of their manifestation were...

Monitoring Results of a Nearshore Disposal Berm

Mixer Viscometer Characterization of AFBC Ash Grout

Design Alternatives for Protection of the Santa Ana River Interceptor Sewer
The Santa Ana River Interceptor Sewer (SARIS) line buried within the floodplain of the Santa Aria River is being threatened by long term degradation of the river bed at the pipeline crossings,...

Finite Element Computer Models for Analysis of Cold-Formed Steel Members

Impacts due to Density Current Deposition in Reservoirs
Different flow pafterns of density currents in reservoirs are discussed. In delta region, lateral density currents from non-stratified flow in the main channel occurs resulting in floodplain...

Propeller Wash Induced Erosion at Quay Walls
The characteristics are examined of the sea bed erosion produced by the scouring action of a ship's propeller wash acting against a quay wall. The rate of development of erosion...

Boundary Layer Theory and Field Bedload

Simulation of Channel Changes Induced by a Reservoir
A fluvial study was made for potential stream channel changes induced by a reservoir. It is generally recognized that a reservoir induces sediment deposition along the upstream channel...

Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...

Potential Flow Instability Theory and Bed Forms
An extended, generalised version of two-dimensional linearised potential flow theory of fully unsteady fluid flow-sediment bed interaction is presented. In contrast to previous potential...
