Wetland Valuation Based Upon Multi-Purpose Performance Evaluation
Wetland protection and restoration have become a top priority in water management. A wide variety of benefits are ascribed to wetland protection, e.g., flood control, water quality improvement,...
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...
A Decision Support System for Dredging the Lower Mississippi River
The paper describes a decision support system proposed to aid short-term scheduling of maintenance dredging activities on the lower Mississippi River for the New Orleans District of the...
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...
Applying Benefits-to-Costs Analysis for Stormwater Improvement Projects
Benefit-to-cost analyses provide a measure of evaluation for the justification, selection, and prioritization of stormwater improvement projects. Facing increased competition for tax dollars...
Optimizing Urban Ground Water Supply Systems
The cost of Pumping comprises a major part of total water operation and maintenance expenses. Most utilities attempt to keep these costs down. However, there are areas of study that may...
A Decision Support System for Water Supply Costing
Accurate cost estimates for water supply system expansions are an important component of the planning process. A spreadsheet-based cost estimating model called SWFCOST was developed as...
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,...
Characterizing Mode I Fatigue Delamination of Composite Materials
Evaluation of two techniques to characterize fatigue delamination using the double cantilever beam (DCB) specimen are presented. The two techniques were the delamination growth onset (G-N)...
Theoretical and Experimental Mechanisms of Toughening in Multi-phase Materials
Multi-phase materials are an important class of materials being developed for aerospace primary structural applications. Multi-phase materials are those materials consisting of two or...
Inspection Goes High Tech
Many believe that rehabilitation of the existing infrastructure�not net construction�will dominate the 1990s. Therefore, accurate condition assessment is crucial, since public works agencies...
Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...
Managing Risks of Hazardous Materials Transportation in Santa Barbara County
This paper presents some potential building blocks which local jurisdictions can pursue to manage the risks associated with hazardous materials transportation (HMT). The recent experience...
