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 are developed....

Shallow Foundations for Tall Structures in Florida
The use of shallow foundation systems with measurable but tolerable settlement of major building complexes constructed in the Miami, Florida area is demonstrated by three case histories, The Omni International,...

Dynamic Formula for Pressure Injected Footings
The mathematical derivation of a dynamic pile-driving formula for the installation of Pressure Injected Footings (Franki Piles) is presented. The usefulness of such a formula, despite the inherent limitations...

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 pile response,...

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 for predicting...

Dilution Analysis for Undirectional Diffusers
The paper discusses the mixing mechanics of submerged, multi-port diffusers used to discharge heated water from steam-electric power plants into shallow receiving waters. An analysis for co-flowing diffusers...

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 plains were found...

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 presently in...

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 existing and...

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 using the method...

Stochastic Generation of Monthly Streamflows
Two streamflow generation models are used to generate monthly flows for Australian streams. In one model, seasonalities and periodicities in the monthly flows are removed and the resulting weekly stationary...

Pump-Sump Design Experience: Summary
The designs of pump sumps for seven different projects, as developed through hydraulic model testing, are compared with published design standards. Modifications to the sump designs, in addition to the...

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 experiments, each...

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 because of its...

Water Yield Estimation in Western United States
The mean annual water yield of a watershed is used in the planning, design, and management of some watershed projects, especially those involving irrigation. A statistical analysis of water yield data...

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 different sample...

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 are effective but...

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 ET was based...

Plastic Rotation of Composite Beams
The sagging rotation capacity of composite beams consisting of a concrete slab attached to a steel beam by a shear connection is studied. Tests are reported on four full-scale beams in the range of ductility...

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 columns introduced...
