Foreign Hydraulic Standards and Guidelines
Standardization in Europe is propelled by the incentive to achieve harmonization of design, testing, inspection and certification methods for an internal market among eighteen European...

Preliminary Recommendations from the Task Committee on Standards in Hydraulics
The Task Committee on Standards in Hydraulics has been given the responsibility of recommending whether or not the American Society of Civil Engineers (ASCE) should formulate standards...

Environmental and Hydraulic Considerations in the Design of a Circulating Water Cooling System
Environmental considerations play an important part in the design of a condenser cooling system. A once-through system may require assessment of a combination of events to determine the...

Design of a Stratified Cooling Channel
Cooling ponds are used for managing waste heat discharges. Cooling ponds are, however, expensive to construct and operate. A cooling channel is studied as an alternative means of managing...

A Microcomputer-Based System for Two-Dimensional Flow Modeling
An integrated, microcomputer-based system has been developed for simulation of two-dimensional, unsteady, free surface flows. The system consists of a finite-element mesh generation code,...

Design of a Self-Regulating Flap Gate
The objective of the research reported here is to improve the design of a flap gate whose function is to maintain a constant upstream water level over a wide range of flow rates. The self-regulating...

Experimental Model Study of Over and Under Baffles
A hydraulic model study of a chlorine mixing channel was conducted at the Hydraulic Research Laboratory of the City of Los Angeles. An arrangement of over-under baffles was used to facilitate...

Tracking Cold Water in a Large Reservoir System
The Tennessee Valley Authority (TVA) Environmental River Resource Aid (TERRA) is a computer workstation graphics display that tracks environmental variables in the power service area....

Modelling Longitudinal Temperature Distribution in TVA Reservoir System
A one-dimensional model has been developed for computation of water temperature in the TVA reservoir system. The model has been successfully used in evaluating the impact of incremental...

Application of a Generalized Risk Dynamic Model to a Spillway Design Flood
Risk analysis can provide a logical basis for selecting the optimal design capacity of a flow conveyance hydraulic structure for the least total cost or specified non-exceeding risk levels....

Visualization of a 3D Model of Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic and water quality model (WQM) of the Chesapeake Bay and its major tributaries has been developed by the US Army Engineer Waterways Experiment...

Visualization of a Groundwater Contaminant Model
Groundwater contamination is a problem of major national concern. Three-dimensional characterization of groundwater contamination is typically required. This paper describes integration...

Visualizing Groundwater Flow
This presentation demonstrates the application of some public domain scientific visualization software tools in the area of groundwater modeling. Specifically, we use these tools to interpret...

An Integrated Model for Fate and Transport of Oil in Rivers
An integrated oil spill model for microcomputers is developed for simulating fate and transport of spilled oil in rivers. This model can simulate the oil slick transformation in transient...

TransAct: An Interactive Transient Analysis Program for Pipelines
The program TransAct is designed to analyze a wide range of transient responses that may have been caused by a complex combination of control actions. For example, there may be the simultaneous...

PC Versatility in Modern Hydraulic Laboratory Data Acquisition Systems
Recent and newly emerging developments in low cost (personal) computing have enabled engineers to implement sophisticated data collection and analysis techniques on computing platforms...

Data Acquisition Systems for IBM Compatible System
Portable data acquisition systems composed of IBM compatible PC/XT/AT computers and analog to digital conversion cards can be configured with relative ease. These systems have the flexibility...

Computerized Data Acquisition for an Undergraduate Hydraulics Laboratory
Basic hydraulics principles and the operation of certain hydraulic systems can be effectively demonstrated with the aid of relatively inexpensive data acquisition and analyses systems....

3-D Free Surface Flow Model Verification
This paper is intended to achieve two objectives: (1) providing the readers and participants of the 1991 ASCE National Conference on Hydraulic Engineering with background information about...

Use of Electronic Microprocessor-Based Instrumentation by the U.S. Geological Survey for Hydrologic Data Collection
The U.S. Geological Survey is acquiring a new generation of field computers and communications software to support hydrologic data-collection at field locations. The new computer hardware...
