Predicting THM Formation with Artificial Neural Networks
An existing mathematical model to predict trihalomethane formation and speciation was enhanced through the use of artificial neural network technology. The model corresponded well with...
Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...
Comparison of Worst-Case and Probabilistic Approaches to Ocean Outfall Mixing Zone Analysis
Two approaches have been used for ocean outfall mixing zone analysis: worst-case approach and probabilistic approach. This paper discusses some advantages and disadvantages of the worst-case...
Contraction Scour at Bridges: Analytic Model for Coarse-Bed Channels
Contraction scour at bridges spanning coarse-bed channels is evaluated based on mass conservation of both water and transported sediment between a reference channel section near the crossing...
A Three Dimensional Oil Spill Model
This paper reports the development and testing of a comprehensive three-dimensional oil spill model. At present time, the model components include advection and turbulent diffusion, vertical...
The HEC NexGen Software Development Project
The NexGen project is developing successor software packages to the existing family of HEC computer programs. Development is occurring via teams comprised of technical specialists, computer...
Hydrologic Modeling System
The Hydrologic Modeling System (HEC-HMS) is new-generation software for precipitation-runoff simulation that will supersede the Hydrologic Engineering Centefs HEC-l program. Technical...
Next Generation Flood Damage Analysis Program
The Hydrologic Engineering Center has developed a next generation Flood Damage Analysis computer program for formulating and evaluating flood damage reduction plans. The program design...
A Comparison of Sediment Routing Models
In this paper the authors have compared the performance of coupled linear and non-linear methods of solution from these generic types, in order to assess their suitability for use in optimisation...
Fish Passage Pool Bedding Analysis
Anadromous fish passages, stream dynamics and the artifical channel segmented into a natural stream should fttnction seamlessly. This paper intends to develop reasonable procedures a designer...
Capillary Pressure-Saturation Relationships in Fracture
Understanding and quantifying unsaturated flow through fractures in rocky slope is important for design and construction of drainage system in large-scale hydraulic engineering. The data...
Estimating Sediment Conveyance Capacity and Deposition Potential in Culverts
In watersheds characterized by high sediment production, culverts must be designed to adequately convey both water and sediment without causing excessive backwater upstream of the culvert...
Integrated Facility Information Systems: Total Information Access
This paper will attempt to fill the void in computer information handling with regards to facility management information by providing those in the water industry with tips and suggestions...
Restoration Design for Urban Streams: Anacostia River Basin, Maryland
Several stream restoration projects have been undertaken by the Army Corps of Engineers in the Maryland portion of the Anacostia River basin. Measures used include bank stabilization,...
An Engineering Information System Application for Water Supply and Distribution Systems
Engineering information systems are characterized by both static infrastructure and dynamic time dependent data. Telemetered readings can often be relatively substantial over an extended...
Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...
Sediment Erosion Rate in the Baltimore Harbor
In-situ erosion experiments were conducted at four selected sites in the Baltimore harbor in May 1995 using the VIMS Sea Carousel. The measurements showed that the erosion rate decreased...
