Optimum Design of Complex Water Resource Projects
Permissible draft from reservoirs is related to reservoir capacity by draft-storage-frequency analysis and the resulting draft-storage curves are expressed in algebraic form suitable for...

Substructure Analysis by Matrix Decomposition
The method uses the substructure transformation inherent in the Choleski decomposition and involves a partial release of the interior coordinates. A comparison is made between the decomposition...

Probabilistic Variations in Ultimate First Stage BOD
Variations in the ultimate first stage BOD are found to be lognormally distributed under the hypothesis that the bacterial oxidation of organic matter is a first order reaction, and that...

Cause of Clay Sensitivity
Factors were examined leading to differences between undisturbed and remolded clay fabrics and interparticle forces. A consideration of available knowledge would suggest that there are...

Cross-Velocity Behavior In Parallel Channel Flow
Exponential decay is found for cross flow velocities superimposed on steady, fully developed axial flows. Experimental data show that this type of flow may occur in the annular gap between...

Foundation Problems In Sanitary Land Fills
Sanitary land fills in the past have utilized marginal or otherwise useless property for the disposal of solid waste. The growing scarcity of building sites close to cities combined with...

Dynamic Analysis by Matrix Decomposition
A method is presented for extracting eigenvalues and eigenvectors of a system using a combination of matrix iteration and matrix decomposition. In addition to the classical procedure for...

Oxidation of Coal Mine Pyrite
The process of pyrite and marcasite decomposition as it occurs in coal mining regions is described as an electrochemical process analogous to the corrosion of iron. The polymorphic minerals,...

Environmental Hazard of Radioactive Wastes
Radioactive wastes may be disposed of by dilution to acceptable environmental levels, by storage for decay (maybe hundreds of years), or by reclamation to useful products. Storage for...

Stresses at Tunnel Intersections
The experimental program described herein was conducted to determine the stress distributions associated with three common types of cylindrical tunnel intersections (tee, cross, and right...

Thermal Decomposition of Human Waste
A study was undertaken to provide information on which a more rational design of incinerators for human waste can be based. The laboratory techniques and method of data analysis may be...

Fluorescent Tracers for Dispersion Measurement
Laboratory tests on the behavior of the fluorescent dyes rhodamine B, Pontacyl Brilliant Pink B, and fluorescein in surface waters of variable quality indicate that Pontacyl Brilliant...

Spectrum of Axisymmetric Turbulence
Scalar equations are derived for axisymmetric turbulence in terms of spectrum functions, and decay of axisymmetric turbulence has been examined in absence of inertial terms....

Refuse-Sludge Compositing in Windrows and Bins
Composting was investigated at Chandler, Ariz, in 2 runs involving 4 windrows and 25 aeration bins of ground refuse and refuse-sludge mixtures; composting materials were turned average...

The Viscous Sublayer Along a Smooth Boundary
Model proposed which visualizes periodic growth and decay of sublayer; magnitude of life period of sublayer can be predicted theoretically and has been checked by experiment; as consequence...
