Hazard Rating for Low Drops

Simulation of the Accuracy of Current Meters

Tracking a Serial Filter
The Humboldt Bay Municipal Water District in northern California conducted pilot testing of extreme/high-rate serial filtration (EHRSF) to see if the process could meet water treatment...

Estimation of Transition Probabilities From Facility Condition Ratings

Snap Buckling of a Delaminated Layer in a Composite Cylinder
We investigate snap buckling of a thin delaminated layer on the inner surface of a contracting thick cylinder. Finite-deflection solutions of the layer with or without considering the...

Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [02/906]s...

Load Rate Effects on Concrete Compressive Strength
Plain concrete cylindrical specimens from six different concrete mixes, 51 mm in length and diameter, were tested in compression quasi-statically at strain rates between 10-6/sec...

Elasto - Plastic Analysis of Cable Net Structures
This paper presents a Newton-Raphson interaction technique which takes account of plastic cable strains while iterating on the nodal equilibrium equations of cable net structures. The...

Borehole Fluid Dynamic Temperature Logging to Evaluate Fracture Hydraulic Properties

Flow Capacity of Rehabilitated Sanitary Sewers

Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....

Pavement Treatment in Ohio Transportation System
This paper presents a modification of the original method in which the concept of fuzzy set theory is applied in the calculation of the PCR. Fuzzy numbers are introduced to represent those...

Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...

Compressibility of Clays: Fundamental and Practical Aspects
The compressibility of natural clays is influenced by strain rate, temperature, sampling disturbance, stress path and some restructuration factors. The first part of the paper reviews...

Using the SedBed Monitor to Measure Bed Load
An acoustic distance measuring device (SedBed Monitor) was developed to accurately measure bed surface transects in a sediment and water recirculating flume. From these transects the rate...

A New Basic Principle for a New Series of Hydraulic Measurements. Erosion by Abrasion, Corrosion, Cavitation and Sediment Concentration
The DECAVER is a novel apparatus able to make new measurements in various domains where an erosion is produced in an aqueous medium. It gives the erosion rate and the accumulated erosion....

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...

Pressure-Time Flow Rate in Low Head Hydro Plants
Very few methods are accepted for measuring the flow in the large intakes typical of low head, run-of-the-river hydro plants. These intakes are characteristically short, non-uniform, non-prismatic,...

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...

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,...
