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....
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...
Model Study of a Hurricane Surge Barrier Gate Valve
Physical model studies were conducted to determine the hydraulic performance of a unique vertical butterfly-gated structure. These studies were also used to determine the torque on the...
Model Studies of Outlet and Intake at McCook Reservoir
Two separate physical models were used to investigate the outflow and inflow into the proposed McCook Reservoir. The proposed reservoir will be located in McCook, Illinois, and will serve...
Loose Riprap Grade Control Structure Design
The Soil Conservation Service has been using loose riprap grade control structures based on the equal energy concept for several years with mixed success. Previous model studies resulted...
Vortex at Hydraulic Intakes with Asymmetric Approach Flows
The formation of vortices at intakes can disrupt normal operating procedures and damage hydraulic machinery. Asymmetric approach flow and a protruding pier (normal wall) contribute to...
Improved Intake Design for Downstream Migrating Fish at Hydropower Plants
Fish guidance efficiency of screens is a function of the submergence of a hydropower intake. The submergence of an intake can be reduced through the use of intake extensions or guides...
Seawater Delivery for Use in Aquaculture Development
Seawater is used extensively in industrial and aquacultural developments world wide, and aquaculture in particular requires large quantities of seawater. Development and design of facilities...
Field Measurement of Hydrodynamics and Sediment Transport of the Mississippi River at Old River
Two detailed field surveys of the hydrodynamics and suspended sediment transport of the Mississippi River at the Old River Control Structure complex were completed in February and June...
A Knowledge-Based System for the Environmental Design of Waterways (ENDOW)
Knowledge-based software systems accept problem descriptions from users and apply logic in order to generate a solution or solution set. These systems function over very narrow problem...
LISP or CLIPS: Selecting an Expert System Tool in Hydraulic Engineering
The transfer of Artificial Intelligence(AI) technology from the research laboratories to the scientific and engineering environments has been made possible by phenomenal advances in computer...
Probabilistic Aspects of Hydroproject Maintenance
A survey of operation and maintenance personnel in the hydraulic structures sector was conducted to learn about the present maintenance approach and the perception of the probabilistic...
Reliability Assessment Method for Flood Forecasts
Peak discharge predictions produced by rainfall-runoff models and used by flood warning and preparedness agencies are subject to uncertainties in the input data, model parameters, and...
Conventional Storm Drainage Which Recharges the Groundwater
Since the demand for water is on the rise, more resourceful means of retaining and controlling the release of stormwater is needed. This retained stormwater may then be used for aesthetic...
Detention Basin Design to Control Flood Volumes
A desk-top method is presented for hydraulic design of detention basins. The main objective is to control the flood volume rather than the peak discharge. The method is based on the pre-determined...
Fluid Mud Problems in Lakes, Reservoirs and Detention Ponds
An experimental study of wind induced surfacing of fluid mud bottoms in shallow water has been conducted. The experiments involved a channel placed within a wind tunnel, where a two-layered,...
Temporary Facilities?Making It Happen, Organization and Logistics
As construction projects become larger, more complex and are constructed both faster and under more adverse conditions--the use of temporary facilities is more prevalent. Temporary facilities...
The Benefits of U.K. Guidance for Temporary Works
In British contracts the Contractor is responsible for the design and execution of temporary works unless the Design Engineer or the Client expressly instruct how the work is to be undertaken...
Legal Principles and Theories
Legal issues are intertwined with all aspects of the technical considerations relating to temporary structures. This paper presents an introduction to the legal theories which relate to...
Liability Insurance Coverages for Designers of Temporary Structures
A recent survey completed by the American Consulting Engineers Counsel (ACEC) indicates that in 1990 approximately 40 claims occurred per 100 firms. There also is an indication that claims...
