Use of Flood Control Features for Environmental Mitigation
The US Army Engineer District, Vicksburg (CELMK), plans to construct up to 167 water control structures, 52 confined disposal facilities, and 47 barrow pits as part of a major flood control...
Solute Transport Modeling under Unsteady Flow Regimes: An Application of the Modular Modeling System
Many existing solute transport codes rely on the assumption of steady (i.e. time-invariant) flow. This assumption severely limits such models, as accurate simulations often require realistic...
Remarks on Computer-Use History in Water Resources
Over the past 50 years, use of electronic computers has radically changed water resources engineering practice. It has enhanced capabilities, reduced costs and improved reliability. It...
Future Directions in Water Resources Education
Water resources education at the undergraduate level must change to properly prepare professionals for the 21st Century. While few changes are needed in technical content, graduates must...
Optimal Planning of Combined Sewer Rehabilitation
The need to rehabilitate many of the existing sewer systems to keep them operational is evident. The development of a rehabilitation plan that optimizes the use of funds is the first step...
Pipe Network Optimisation Using Genetic Algorithms
A new optimization technique of generic algorithms has recently been successfully applied to pipe network optimization. In this paper a parametric analysis is carried out of the genetic...
Combined Sewer Overflow Abatement Planning Based on SWMM EXTRAN Modeling
This paper discusses use of the Storm Water Management Model (SWMM), with the EXTRAN block as the hydraulic transport mechanism, as a tool for developing a facilities plan for abating...
Interactive Decision Support for Hydrologic, Hydraulic, & Instream Flow Criteria
Most often, impacts on natural resources from alternative river discharges are not quantified. The personal computer (PC) can provide access to useful techniques for analyzing multiobjective...
A Raft System for Large River Hydraulic Measurements
Collection of hydraulic data in large rivers is a difficult, time consuming, and occasionally perilous task. High water velocities, considerable depths, and wide channels present obstacles...
Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....
Expert System for the Preloading Method of Ground Improvement
Design practice of the preloading method, which is one of the ground improvement techniques, applied for the hydraulic fill area includes quite complicated problems, especially when draining...
Verification of Real-Time Software for Active Structural Control
In this paper we give an overview of our preliminary work in verifying the reliability of real-time software systems for active structural control. While there have been numerous studies...
The Reliability Program in Truncated JC Method
JC method is in common use in the structure reliability analysis. In this paper, the program which can be used as to consider the truncated distribution has been proposed, With this method...
