Pavement Roughness and Rideability: A State-of-the-Art Review
This paper reports on the results of a review of the literature and ongoing research concerned with pavement roughness and rideabiity. The material covers definitions and concepts, subjective...

Critical Appraisal of Endochronic Theory for Soils

Rate of Energy Dissipation and Sediment Transport

Stormwater Detention—Downstream Effects on Peak Flow Rates

Development of Simplified Detention Sizing Relationships

Pile Load Tests: Cyclic Loads and Varying Load Rates
Two series of axial load tests were performed on four 14-in. (356-mm) diam, open-end, steel pipe piles at an interval of about 320 days. Pile lengths of 40 ft or 50 ft (12.2 or 15.2 m)...

Rejuvenation of Failed Soil Absorption Systems
The use of hydrogen peroxide as an oxidizing agent was shown to be effective for rejuvenating wastewater soil absorption systems which have failed due to crust or organic mat buildup....

Clustering Model for Correlated Load Processes
Many loading on structures (such as wind, wave, snow, and rain-on-snow) may be due to a common source and have a tendency to cluster around common points in time so that the occurrence...

Two Bed-Load Formulas: An Evaluation
An evaluation of formulas is presented for the prediction of bed load in sand-bottomed channels. The evaluation is done by measuring both the hydraulic data needed for the formulas and...

Furrow Advance Rates under Surge Flow Systems
Two field tests were conducted to study the effect of cycling furrow inflows on advance rates. Earlier investigations had demonstrated the concept and termed it surge flow irrigation based...

Development of Solutions for Level-Basin Design
The procedures are examined for obtaining reasonable estimates of distribution uniformities for a wide variety of flow rates, length of run, infiltration characteristics, and flow resistance...

Particle Counter for Sediment Transport Studies
An acoustic instrument for the measurement of the mass transport of sand-sized sediment particles in laboratory and natural transport systems has been developed. The instrument consists...

The Influence of Air Flow Rate on Line Diffuser Efficiency and Impoundment Impact

The Effect of Filler on the Mechanical Properties of an Elastometer at High Strain Rates

Littoral Sand Transport from Longshore Currents
Prediction of sand transport rates along beaches in a shore-parallel direction is necessary to determine: 1) Dredging quantities at inlets; 2) the effective life of various coastal structures...

Computation of Bed Load Using Bathymetric Data
A method of calculating bed-load transport is presented. This method takes advantage of the rapid bathymetric surveys that can be made in large rivers. The proposed equation is based on...

Simulation Modeling of Primary Clarifiers
A circular primary clarifier model is developed that utilizes flow rate, influent suspended solids, and raw sewage settling property data to produce a temporal-spatial matrix of suspended...

Anaerobic Digestion of Cannery Tomato Solid Wastes
Two major problems facing the food processing industry are solid waste management and energy cost. Anaerobic digestion of tomato solid waste, a means of both waste treatment and energy...

In-Situ Volume-Change Properties by Electro-Osmosis - Theory
The basic concept involves incorporation of a simple electrode system in a field probe, measurement of pore-water pressure changes at the electrodes as a function of time in response to...

Low Sediment Transport Rates Over Flat Beds
Flat sediment beds composed of lightweight plastic discs were laid under two conditions of water flow, and subsequently eroded as bed load. The low sediment transport rates were correlated...
