Load-Settlement Prediction of Footings on Steep Slopes
The use of spread footings on slopes is a common practice in the design of bridge foundations. Footings are generally constructed in the slope or at its crest to minimize the bridge length,...

Measurements of the Hydrodynamic Lift and Drag Forces Acting on Riprap Side Slope
Direct measurements have been made of lift and drag forces acting on a 20.1 mm spherical particle placed within the riprapped 1.5 H: 1 V side slope of a 10 m long channel which was protected...

Factors Affecting Accuracy of Slope-Area Discharge Determination of the September 1992 Flood in Raven Fork, Western North Carolina
For the flood of September 10, 1992, in Raven Fork, Swain County, North Carolina, a peak discharge of 460 cubic meters per second was computed by using the slope-area method. Accuracy...

An Alternative Equation for the Mean Velocity in Gravel-Bed Rivers and Mountain Torrents
Including new field data in the slope range of torrents up to 63%, an empirical equation is developed to express the mean flow velocity in terms of the flow rate, the slope and a characteristic...

Roughness Coefficients for High-Gradient Channels in New York State
Manning's roughness coefficients (n values) were computed for a range of flows at six streams in New York State (USA) that have high energy gradients (greater than 0.002) and large median...

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....

Discharge-Frequency Relationships in Distributary Flow Systems
The paper describes discharge-frequency relationships in distributary flow systems. The stream network that makes up the flow system is described in terms of how the various stream segments...

Conservation Properties of the Mild Slope and Boussinesq Equations
Common water wave evolution equations, such as the mild slope equation, parabolic approximations and Boussinesq equations, are approximate statements of conservation laws. A feasible measure...

Irregular Wave Run-Up on Composite Rough Slopes

A Study on Mathematical Model for Sediment Yield in Mountain Regions with Large Hillside Slopes
Based on the characteristics of water and soil loss in mountain region with large hillside slopes in southwest of China, the equations of runoff formation and sediment yield are obtained....

Application of Spencer's Method for Slope Stability Analysis
For slope stability analysis with general, arbitrarily shaped failure surfaces, the Spencer's method has been found to provide a reasonably accurate result. This method satisfies both...

Holding a Shorelind with a Buried Revetment
Two shoreline modification projects were designed that use a new application of an old idea to provide erosion protection and improve shoreline access and aesthetics. The innovation consists...

The Fraser River Delta, British Columbia: Architecture, Geological Dynamics and Human Impact
The Fraser river delta is the largest delta in western Canada. It is an important coastal ecosystem and an area of explosive urban and industrial growth lying within the most seismically...

Hydraulic Modeling of Alluvial Plains (Slopes) and Alluvial Fans Using DAMBRK
The design of hydraulic structures such as bridges on distributary flow areas and alluvial fans require methods that can adequately determine discharges at the structures. Flow conditions...

Application of 3DFEMWATER to Assess Capping Alternatives at a Steep-Slope Hazardous Waste Disposal Site

Effect of Moisture and Bulk Density Sampling on Neutron Moisture Gauge Calibration
Three moisture and bulk density sampling methods were evaluated for use in neutron gauge calibration. Each of the methods was comprised of a single core or portions of a core taken during...

The Influence of Slope and Surface Roughness on Trapezoidal Free Overfall Characteristics
The brink depth-discharge relationship for trapezoidal free overfalls was investigated including the effects of slope and roughness. The theoretical relationship is based on the momentum...

New Austrian Dam Side-Channel Spillway
The Loma Prieta earthquake of 17 October 1989 damaged the chute spillway at the Austrian Dam near San Jose, California. The replacement spillway, with a higher design discharge of 11,500...

An Optimization Approach to River Adjustments
The adjustment of alluvial channels is presented here as a non-linear optimization problem in which the ideal channel will tend to adopt an optimum configuration subject to the imposed...

An Empirical Model for the Volume-Change Behavior of Debris Flows
The potential travel down hillsides; movement stops where the volume-change behavior of flows as they travel down hillsides ; movement stops where the volume of actively flowing debris...
