Getting the Lead Out
When officials from Omaha, Neb. announced an ambitious plan to revitalize an abandoned stretch of land along the Missouri River, the land itself presented one of the biggest problems....

Closing Hazardous Landfills
Designing and constructing covers for uncontrolled hazardous-waste landfills can pose some special problems�such as differential settlements as great as 50% of landfill thickness. Under...

Building GIS Relationships Spatially and Politically
This paper advocates that the technological aspect of building a spatial GIS is not the critical factor for a successful multi-participant installation. Rather the political relationships...

Understanding Potential Legal Liabilities of Water Resource Professionals and How to Avoid Them
The salvation of the country's water resources is one of the most important problems facing it today. Focused, as they are, on a problem of such overwhelming significance,...

Siting of a Reclaimed Water Reservoir
The City of Santa Rosa (City), California, retained Woodward-Clyde Consultants to identify, evaluate, screen and rank potential sites for construction of a dam and reservoir to store reclaimed...

Risk-Cost Analysis Under Uncertainty for Dredged Material Management
Fuzzy Composite Programming is used to conduct a risk-cost trade-off analysis under uncertainty for a simplified dredge material disposal problem. Uncertainties inherent in the components...

Forthcoming ASCE/WPCF Manual of Practice
The forthcoming ASCE/WPCF Manual of Practice for the Design and Construction of Urban Stormwater Management Systems includes, as Chapter 1, a derivation of the following text. This chapter...

Construction Contract Documents for Stormwater Facilities
This paper provides an overview of the elements of an acceptable package of contract documents for stormwater facility construction. Thoughtful an meticulous assembly of contract documents...

Pricing Policy for Water Services
Prices and pricing strategies are described in terms of their functions and revenue objectives applicable to water services. Ten pricing objectives are defined in terms of how the objective...

Texas Reservoir Projects: Permitting & Mitigation
Recent reservoir projects in Texas were reviewed on the basis of permitting and mitigation, and subsequent project costs. We document trends of increasing time to prepare and process permit...

Summary of the National ASCE Task Committee on Costs-Benefits of Various Design Frequencies for Urban Drainage Systems and Flood Control
The National ASCE Task Committee on: 'COSTS-BENEFITS OF VARIOUS DESIGN FREQUENCIES FOR URBAN DRAINAGE SYSTEMS AND FLOOD CONTROL' recommends that public officials...

Application of Artificial Neural Networks to Composite Ply Micromechanics
Artificial neural networks can provide improved computational efficiency relative to existing methods when algorithmic description of functional relationships is either totally unavailable...

A New Finite Element Formulation of the Generalized Laminated Plate Theory
The Generalized Laminate Plate Theory (GLPT) predicts stress distributions in laminated composite plates with accuracy comparable to a full three-dimensional analysis. The original implementation...

Prediction of Transverse Shear Stresses for Various Isoparametric Thick and Thin Shell Elements
Utilizing three-dimensional equilibrium equations (often referred to as an Equilibrium Method (EM)), an estimation of transverse stresses for fiber-reinforced laminated doubly curved shells...

hpVersion of the Finite Element Method in Boundary Layer Problems
The performance of hp-version of the finite element method in the case of boundary layer problems of convection-diffusion type is presented. The method is also considered in the case of...

Nonlinear Probabilistic FEM for Composite Shells
A probabilistic finite element analysis procedure for laminated composite shells has been developed. A total Lagrangian finite element formulation employing a degenerated 3-D laminated...

Nonlinearities and Imperfections in Creep Stability
The effects of material and geometric nonlinearities and imperfections on the 'safe-load-limit' and the 'safe-service-period' of structures...

Perplexing Issues in Concrete Softening
We explore some of the proposed techniques for modeling 'softening' via the constitutive model. We seek a framework which is both theoretically sound and physically...

Computational Damage Modeling for Timber Reliability Analysis
Damage models for creep-rupture are used in conjunction with stochastic load models to evaluate lifetime failure probabilities of timber members and systems. This paper examines damage...

Diastolic Function Using 3-D Echo Reconstruction and Finite Element Analysis: Applications for Study in Animal Models and Patients
We have initiated animal experiments using three-dimensional reconstruction of echocardiographic recordings and finite element analysis to evaluate the effects of alterations in preload,...
