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...

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...

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...

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...

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...

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...

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...

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...

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...

Generalized Stiffness Matrix for Thin Walled Beams
Stiffness matrix for a structural member is obtained using the differential equations derived by V.Z. Vlasov. Presence of additional off-diagonal elements over the conventional tridiagonal...

Strength of Composite Beams at Web Openings
A model for the strength of steel-concrete composite beams with unreinforced, rectangular web openings is presented. The model includes the contribution of the concrete slab to shear strength,...

Method for Analysis for Guyed Towers
A method for static analysis of guyed towers is extended and applied to problems in three dimensions. The tower and guy cables may be loaded by arbitrary distributed or concentrated forces,...

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...

Finite Beams on Elastic Foundation with Restraints
A solution is presented of the differential equation of finite beams with elastic restraints, resting on a Winkler foundation in terms of the initial conditions at one end of the beam....
