A Comparison of L-Moments with Method of Moments
A comparison of the Conventional Moments Method (CMM) with the L-Moments Method (LMM) for selecting a distribution is made. Five distributions GEV (Generalized Extreme Value), LNO (Lognormal),...

Additional Years of Record and Peak Discharge
The effect of additional years of stream gaging records is analyzed for stream gages in Nebraska. Frequency estimates are based on procedures outlined in Bulletin 17B, including skew coefficient...

Local Scour at Skewed Bridge Piers
Presented herein are experimental data showing the influence of pier skewness, also referred to as angle of attack, on depth of local scour at rectangular and oblong bridge piers. The...

Rainfall Depth-Duration-Frequency Analysis for Major Cities in Taiwan
The annual series of extreme rainfall amounts for various durations are compiled. The statistics such as mean, standard deviation, coefficient of variation, coefficient of skewness, and...

Local Scour at Bridge Piers in Alberta—Case History
A two span steel truss bridge with a rectangular concrete central pier was built over the Oldman River near Brocket in south-west Alberta in 1954. Initially the bridge was built square...

Nondestructive and Destructive Testing of a Three Span Skewed R. C. Slab Bridge
A three span, skewed, reinforced concrete slab bridge was field tested to destruction by the authors. Before the actual destructive test, nondestructive tests were performed to determine...

Rainfall-Runoff Characteristics of Rangitaiki and Whirinaki Watersheds
The Rangitaiki and Whirinaki watersheds in New Zealand have considerably higher storage and infiltration rates than others in New Zealand. The Rangitaiki watershed is flat compared to...

Museum Showcases the Future
On May 4 in Philadelphia, the Franklin Institute's new wing, called the Futures Center, will open to the public. When the institute's neoclassic main buiding...

Stochastic Modeling of Monthly Flows in Streams of Arid Regions
A new stochastic model is presented herein which is applicable to simulating monthly flows of streams in arid regions. The model enables one to reproduce the percentage of zero flows in...

Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...

Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...

Large Low-Speed Generators with Skewed Supporting Parts
During the past decade, the demand for hydro-generators has been for increasingly high ratings, up to the present maximum of about 800 MVA. These low-speed machines have rotor diameters...

Longitudinal Dispersion in Rivers: A Dead Zone Model Solution
The longitudinal dispersion of tracer material in rivers is often analyzed based on the one-dimensional convective diffusion equation developed by G.I. Taylor. However, the persistent...

A Physical-Chemical Interpretation of Mean and Extreme Values in Acid Precipitation
A physical-chemical model is used for the interpretation of mean and extreme concentrations in acid precipitation. Chemical concentration frequency distributions tend to be skewed, as...

Beach Response to Spurs and Groins

Three-Parameter Probability Distribution of Best Hydrologic Bounds

Structural Response of Skew RC Box Girder Bridge
Analytical and experimental results obtained in a study of a large-scale 45° skew two span four cell reinforced concrete box girder bridge model are presented. The model, which was a 1:2.82...

Ultimate Strength of Skew RC Box Girder Bridge
Analytical and experimental results obtained in a study of a large-scale 45° skew two span four cell reinforced concrete box girder bridge model are presented. The model, which was a 1:2.82...

Uniform Flow over Skew Side-Weir
A rectangular channel with a skew side-weir is designed to obtain a uniform discharge distribution over the side-weir. Numerical and experimental results are presented. Geometric and flow...

Behavior of Skewed Beam and Slab Bridge Decks
A stiffness method for the analysis of monolithic beam and slab skew bridges is developed, the deck geometry being modeled with two-node beam and four-node skew plate finite elements....
