Multivariate Techniques for Water Quality Analysis
The objective of this study was to demonstrate the application of multivariate statistical techniques towards the understanding of variables affecting water quality. One of the major problems...

Determining Streamflows from Geomorphic Parameters
To predict streamflow, hydrologists and geomorphologists have sought to relate streamflows to geomorphic parameters, and vice versa. Data continuity problems were addressed by statistical...

Limit Pressures of Rigidly Clamped Circular Cylindrical Shells
In this paper the exact limit pressure is examined for a circular cylindrical shell rigidly supported at both ends. The Tresca yield criterion is assumed, with shear deformation neglected....

Experimental Study of Wave Transmission
Unsteady non-Darcy flow in rectangular rock-fill embankments with impervious cores was studied experimentally by subjecting the embankments to nonlinear, shallow water waves. Crushed rock...

Fatigue Concepts for Concrete Airport Pavement Design
Correlation is shown between fatigue and coverage methods for evaluating the effects of repeated aircraft loads on concrete pavements. Based on the correlation, a specific procedure is...

Regional Sediment Yield Analysis of Alaska Streams
Sparse suspended sediment data for Alaska were evaluated to verify previous work on regional sediment yield relationships and to test alternative regression correlations using readily...

Stoplog Closure—Model Prototype Correlation
Hydraulic model tests give accurate solutions to problems involving complicated flow conditions but designers should adopt designs which avoid unpredictable situations. To achieve one...

Soil Parameters for Design of Mt. Baker Ridge Tunnel in Seattle
Experiments were conducted in the field and in the laboratory on subsurface soils encountered along the proposed Mt. Baker Tunnel in Seattle, Wash., to determine the modulus of horizontal...

Gust Factors and Alongwind Pressure Correlations
An expression for gust response factors for tall buildings is derived using an analysis, based on first principles, of three-dimensional structures subjected to random loading. The expression...

Effects of Geometry Change on Essential Features of Inelastic Behavior
Essential features include normality or lack of normality of the inelastic strain or displacement rates to a meaningful surface, convexity or concavity of this surface, stability, and...

Probabilistic Short-Term River Yield Forecasts
A predictive model, employing a first order autoregressive structure, which enables estimation of the probability distributions of streamflow volumes in future seasons is developed. The...

Correlation of Environmental Impact Evaluations and Urban Highway Transportation Planning

A Profile of ASCE Membership
The 1967 National Engineers' Register survey data for ASCE members are presented in tabular form with an analysis. Basic characteristics are tabulated for members' citizenship, age, geographical...

Parameter Estimation for First-Order Autoregressive Model
Stochastic simulation of streamflow depends upon estimation of the correlation structure of the series. Several estimators of the autocorrelation coefficient are investigated and all are...

Statistical Analysis of Live Load in Column Design
Influence surfaces and simple probability theory indicate the relative importance of various characteristics of live loads in an analysis of structural safety. The approximate loading...

Mapping from Space
Remote sensing of the earth promises to become an operational tool of the engineer and the scientist within the next few years. There are no real technical limits on the uses of data from...

Surveys for South Shore Rapid Transit Construction
Because of the lack of rapid transit construction within this country during the last quarter century, little experience has been gained in the various aspects of surveying which are involved....

Reliability of Refraction in Polar Astronavigation
The use of radiosonde data offers the possibility of overcoming restrictions imposed by the polar environment and of establishing the reliability of existing refraction tables for use...

Relative Density and Relative Compaction
Since the pioneering work of R. R. Proctor some 40 years ago, soil mechanics engineers and contractors have been accustomed to evaluating a compacted fill in terms of relative compaction....

Flat-Vee Weirs in Alluvial Channels
Sediment tests were carried out with the ultimate aim of providing design data for flat-vee weir installations in alluvial channels. The model study was of an idealized nature but did...
