Vibration of Noncircular Foundations
Evaluation is made of various factors which are not considered in the elastic half-space theory used in the analysis of foundation vibration. From the vibration tests of twenty-two model...

Space Correlations in Round Turbulent Jet
Turbulence measurements were conducted in the mixing region of a turbulent round jet having a 0.2 ft diam and an efflux velocity ranging from 35 to 50 fps. All three components of the...

Coliform-Fecal Coliform Bacterial in Tidal Waters
The fecal coliform-coliform relationship has been examined for several estuaries on Long Island to evaluate proposed fecal coliform standards for shellfish growing waters. The level of...

Unit Graphs for Nonuniform Rainfall Distribution
Correlation between Snyder's basin constants Ct and 640 Cp and basin physical characteristics...

Regional Drought Frequency Analysis
Analysis of severity and duration of droughts in central United States and Massachusetts is compared with available drought data from California, the Clearwater River, Illinois, the Soviet...

In Situ Measurement of Solids in Final Clarifiers
An apparatus was assembled and a method was developed for the in situ measurement of solids concentration gradients occurring in final clarifiers of an activated sludge process. Tests...

Load Transfer for Axially Loaded Piles in Clay
An analytical method for developing a theoretical load-settlement curve for axially loaded piles in clay is presented. The method is based on the correlation of the ratio of load transfer...

Strength of Round Steel Columns
Recommendations are presented for the design of solid round columns made of any commercially available structural steel. These design formulas are based on experimental and analytical...

Spurious Correlation in Hydraulics and Hydrology
Spurious correlation is the correlation built into ratios, products, or other functions of two sets of random variables when the two sets have some elements in common. In hydraulic and...

On the Probability Distribution of Wave Force and on Introduction to the Correlation Drag Coefficient and the Correlation Inertial Coefficient

Face-Wrinkling Mode of Buckling
Two methods are presented for predicting face-wrinkling failure stresses for edgewise loaded sandwich panels. One method, based on Forest Products Laboratory theoretical parameters, is...

Estimating Evaporation from Insolation
A previously developed equation correlation evaporation and insolation quantities with air temperature for a local region has been recomputed from a wider geographic distribution of data....

Some Observations on the Undular Jump
For the surge in an open channel in which the outflow is suddenly cut off, the water under the surge profile is brought to rest relative to the bed. The hydraulic jump resulting from applying...

Population Forecasting by Sanitary Engineers
A critical evaluation of population forecasting techniques currently (1964) used by sanitary engineers is presented. Methods for estimating population are reviewed and sources of population...

Correlation of Future Vehicle and Highway Design
DataNotAvailable...

Dispersion-Permeability Correlation in Porous Media
Longitudinal dispersion and permeability tests were performed in the Darcy flow regime using uniform porous media consisting either of spheres or sand grains....

Electronic Surveying: Accuracy of Tellurometer Over Short Distances
Experience has shown that the relative accuracy of microwave distance measuring instruments drops rapidly when measurements are made over short lines. This is caused by the presence of...

Correlation of Predicted and Observed Suspension Bridge Behavior
Validity of model tests concerning behavior of suspension bridge in wind depends on possible scale effect, and difference between natural wind and wind used in model tests; test data are...

Turbulent Diffusion and Anemometer Measurement
Although direct theoretical connection between Lagrangian correlation (Lc) and Eulerian correlation (Ec) coefficients was not found, it is shown that empirical relation can be established;...

Turbulent Diffusion and the Reaeration Coefficient
Results of study of oxygen absorption phenomenon, mechanism causing transfer of oxygen into water, and development of practical method of estimating oxygen transfer rates in open channel...
