Coal-Fired Reference Plants: Project Benefits
It is expected that requirements for new electric generating capacity will necessitate shortened engineering and construction schedules for future coal fired projects. The reference plant...

Design of Fan Foundations
A design approach for satisfactory and cost effective rotary machine foundations, especially fan foundations, is presented. The often used minimum stiffness criterion for the foundation...

Horizontal Stiffness and Damping of Single Piles
Simple expressions are developed for the equivalent horizontal spring and damping coefficients at the top of an end-bearing pile embedded in a uniform linear soil. Beam on elastic foundation...

Probabilistic Analysis of Deposit Liquefaction
A probabilistic methodology is presented for liquefaction analysis of horizontally layered sand deposits, subjected to vertically propagating seismic S waves. Three different deposit models...

Single Pile Response to Cyclic Lateral Load
An analysis is presented for the deflection of a pile in clay subjected to quasi-static cyclic lateral loading. This analysis is an extension of the elastic continuum analysis for static...

Hydrothermal Analysis of Lakes and Reservoirs
The impact of Hunter Rouse on the application of fluid mechanics to hydraulic engineering practice in the United States is reviewed. The development of physical and mathematical techniques...

Carrying Capacity of Flood Plains
The field data of flood flows for several streams were analyzed to determine the distribution of flow in the main channel and in the flood plains. The discharge carrying capacity of flood...

Lower Flow Regime Bedforms: Rational Classification
A classification of lower flow regime bedforms is proposed, based upon consideration of the effect of water flow on the shape and size of bedforms, which is more rational than other systems...

Sediment Analyses for Urbanizing Watersheds
An analysis of channel modifications for Harding Ditch, the main drainage canal for two urbanizing watersheds near St. Louis, Missouri, required an estimate of depositional changes between...

Sewer Network Routing by Dynamic Wave Characteristics
Hydraulics of unsteady flow in storm sewer networks is investigated by using a dynamic wave simulation model. The Illinois Storm Sewer (ISS) Model solves the complete dynamic equations...

Advance and Runoff-Surge Flow Furrow Irrigation
Furrow advance and runoff evaluations were conducted on a field having a silt loam soil using pulsed water applications. The irrigation method, defined as surge flow, was applied in two...

Application of Penman Equation Wind Function
The Penman equation for computing evapotranspiration is frequently applied as the basis of irrigation system design. It has seen widespread application when sufficient data are available...

Volume-Accuracy Relationship in Soil Moisture Sampling
The number of soil samples required to achieve a given level of accuracy of the mean value is directly proportional to the variance of the samples. Analysis of a set of soil samples of...

Managing Salinity in Irrigated Agriculture
Excessive accumulation of salts in soils and ground water has plagued the irrigated semiarid and subhumid regions of the world for centuries. The structural measures of salinity control...

New Evapotranspiration Crop Coefficients
Improved crop coefficients for various Pacific Northwest irrigated crops were developed for estimating crop evapotranspiration (ET) from estimates or measurements of reference ET. Reference...

Restrained Crooked Aluminum Columns
The strength of aluminum pinned crooked columns has been derived as the basis of a design column curve. The effective length factor concept has then been presented and a value for crooked...

Small End Restraint Effects on Strength of H-columns
A parametric study of the strength and behaviour of an axially loaded wide-flange steel column is investigated from the viewpoint of a beam column analysis using the approximate deflection...

Post-Buckling of Plates in Compression and Bending
The elastic post-buckling behavior of rectangular plates in combined compression and bending is presented. The theoretical investigation begins with the Marguerre's compatibility equation...

Decision Strategy for Asphalt Pavement Recycling
A decision model that uses utility theory to the decision making process in selecting optimum techniques for asphalt pavement recycling is presented. The model requires the identification...

New Structural Systems for Zero-Maintenance Pavements
Unique and infrequently used concepts and systems suitable for zero-maintenance pavements are identified. For this study, a zero-maintenance pavement is defined as one that will provide...
