Numerical Modeling Study of Lake Pontchartrain
A Hansen-type hydronamical-numerical model is shown to adequately simulate actual wind circulation, water levels, and particulate matter dispersion in Lake Pontchartrain. The model is...

DO Model for Discharges from Deep Impoundments
A simple model is presented for the annual dissolved oxygen (DO) cycle of releases from the hypolimnion of deep impoundments. The model includes mathematical formulations and rate constants...

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,...

Water Law Primer
An overview of legal principles controlling water resources use and development is provided. The body of legal principles is a combination of federal and state law, with federal law generally...

Aggregate Gradings for Nuclear Concrete
Evaluation of concrete shows that segregation, inherent in rehandling of coarse aggregate, is significantly reduced in the large mixers used in concrete production. The investigation also...

TVA Hydro Scheduling Model: Theoretical Aspects
The optimization procedures used in the Tennessee Valley Authority (TVA) HYDROSIM model are described. Scheduling of the TVA operated reservoir system poses a stochastic, nonlinear, multireservoir...

Finite Element Method for Interface Problems
A method for incorporating interface discontinuities in a finite element analysis of discontinuous media is presented. For computational purposes the procedure is implemented into the...

Short Line Change Estimates Neat Oarai, Japan
To estimate the shoreline changes near the Port of Oarai when the groin was built, the field observations were done and the characteristics of the coast were investigated. A present shoreline...

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...

Flexible Pavement Evaluation and Overlay Design
A rational method for flexible pavement evaluation and overlay design using the Dynaflect deflections is presented. Evaluation charts and design curves are based primarily on the results...

Concrete Plate Reinforcement: Frictional Limit Design
The limit design of a regular rectangular reinforcing net in a concrete plate subjected to arbitrary normal and shear forces and bending and twisting moments is studied. The assumptions...

Nonlocal Variational Method in Stability Analysis
A mathematical technique is developed for analyzing the stability analysis in terms of effective stresses. The stability equations are obtained based on limiting equilibrium conditions....

Flexural Strength of Flat Slabs at Exterior Columns
The flexural strength of exterior panels of flat slab structures is investigated by use of Yield Line Theory. Six controlling, geometrically admissible, collapse mechanisms are identified,...

Natural Gas Transmission System Optimization
This paper develops a general model and advances a solution methodology for the optimum design of natural gas transmission networks. The complete static design problem addressed is that...

Well Hydraulics in Vertically Heterogeneous Formations
Comparative analysis of time-dependent drawdown alterations caused by the heterogeneous properties of stratified formations is given based on solutions developed under different assumptions...

Inflation and the Construction Industry
Inflation has become a chronic problem whose effects permeate the entire construction industry. Owners are not only paying for the increased costs of facilities and capital but also for...

Prestressed Decks in Continuous Composite Bridges
A convergent series solution, using the concept of equivalent orthotropy, is employed to analyze continuous composite bridges under static loads. The effect of the interaction between...

Saltation in Water Dynamics
An evaluation of the fluid forces exerted on a bed load particle is presented. The study used strobe photography to measure the kinematics of a sphere moving via saltation along the bed...
