Palaeohydraulic reconstruction of floods in upland UK bedrock streams: progress, problems and prospects
Palaeoflood evidence from five small upland Pennine catchments in the UK is used with the HEC-2 flow routine to simulate Holocene peak discharges. Even allowing for uncertainty, sensitivity...
Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
A Physically-Based Model of Channel Widening
The application of many existing models of river channel morphology is limited by their inability to account for bank erosion and changing channel width through time. This paper outlines...
Theoretically-Derived Regime River Width
The governing equations describing the motion of fluid and non-cohesive sediment particles in alluvial channels are combined to analytically determine the equilibrium surface width of...
Boundary Shear in the Vicinity of River Banks
Some experimental data are presented concerning the distribution of boundary shear stresses in trapezoidal open channels for both inbank and overbank flows. The local shear stresses on...
Determination of Geometry and Stress Distribution of an Optimal Stable Channel
A numerical model which determines the geometry of a threshold channel was recently developed (Diplas and Vigilar, 1992). This is important in the design of irrigation canals, channelization...
Equilibrium Geometry of Channels with Cohesive Banks
An optimization model is used to assess the stability of gravel-bed rivers with cohesive channel banks and to determine the effect of the bank stability on the equilibrium hydraulic geometry....
Characterization of Incised Channel Development
A combination of hydraulic and geotechnical techniques have been applied to predict future cross-section morphology in incised channels. The SAM program (Copeland, 1991) computes combinations...
Width Adjustment: Relative Dominance in Unstable Alluvial Streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment...
Field Evaluation of the Sediment Transport Model Stream with a Bank Erosion Component
The graded sediment routing and stream bed evolution model STREAM of Borah, Alonso and Prasad was expanded earlier by incorporating a riverbank erosion component of Osman and Thorne. In...
Toe Scour Protection Methods
Toe scour protection is an important element in bank protection projects because undermining by scour at the toe is one of the major causes of failure of bank protection. Existing toe...
Management of Sediments on the Red River Waterway Project
The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks...

Under Cover
The impermeable properties of flexible membrane liners have made them hot properties for landfill closure-cover systems. But slip-resistant clay might still be the best cover material...
Improved Torsional Analysis Procedure for Single Story Structures Subjected to Seismic Motion
An analytical procedure is developed that enables designers utilizing the UBC planar lateral force procedure to accurately account for the additional lateral response due to torsion without...
Response of Knee-Brace-Frame Under Seismic Loading
Recently a new framing system called the Knee-Brace-Frame (KBF) has been proposed for seismic resisting structures to overcome the deficiencies of moment resisting frame and concentrically...
Wind Design and Analysis for the Normandy Bridge
The Normandy Bridge will represent an important progress in the field of cable-stayed bridges, with a main span 856-metre long. This paper explains how the design has been oriented to...
85 Stories in Kuala Lumpur?The 5th and 6th Tallest Buildings in the World
A concrete core and cylindrical concrete tube structure provides a safe, elegant, efficient and constructible solution to the challenge of designing the world's 5th and 6th tallest buildings,...
