Survival of Atlantic Salmon Smolts Bypassed Through Ice-Log Sluices Determined by the HI-Z Turb'N Tag
The HI-Z Turb'N Tag was used to assess injury and mortality incurred by Atlantic Salmon (Salmo salar) smolts bypassed through ice-log sluiceways at two stations. Both sluiceways were similar...
Ask Young Clupeids if Kaplan Turbines are Revolving Doors or Blenders
Previous estimates of low survival (18 to 38 %) of young clupeids (American shad, blueback herring, and alewife) in passage through hydro turbines have led many to conclude that turbines...
Variations Encountered in Design Analysis of Local Scour at Drop Structures
Proper design of drop structures can prevent failure due to scour at upstream structures, like bridges. An important aspect of drop-structure design is the prediction of the local scour...

The Dallas-Fort Worth, Texas metroplex has 7 cities with populations of at least 100,000 that are required to meet national Pollutant Discharge Elimination System (NPDES) permitting requirements...
A Simple and Reliable Method For Analysis of Water Supply Distribution
The proposed analysis, may be regarded as a bridge between the practical sample analysis and the optimization model development. From the analysis and observation of water distribution...
Development of Enhanced Tools for the Integrated Analysis of Reservoir and Power System Operations
The Tennessee Valley Authority (TVA) and the Electric Power Research Institute (EPRI) have initiated a collaborative project - the INTEGRAL Project - to develop improved tools for coordinating...
Emergent Techniques in Scour Monitoring Devices
This paper presents a brief status report of a research and development project funded by the National Cooperative Highway Research Program (NCHRP) to develop and test scour monitoring...
Predicting Critical Scour Stage at Bridges
After an initial level I screening process, most level II bridge scour studies result in recommendations for costly scour countermeasures. Typically, existing transportation budgets cannot...
Practical Comparison of One-Dimensional and Two-Dimensional Hydraulic Analyses for Bridge Scour
The Kentucky Transportation Cabinet, Department of Highways is working with the Indiana Department of Transportation and the Federal Highway Administration to plan, design, and construct...
Quantity and Quality of Dry Weather Flow in Las Vegas Valley, Nevada
In recognition of the potential for dry weather flows to convey pollutants from the Las Vegas Valley, the potential economic and resource value of these flows within the Valley, and the...
Scour at a Bridge Over the Weldon River, Iowa
Contraction scour at the State Highway 2 bridge over the Weldon River in south-central Iowa was caused by a flood of record proportions on September 14 and 15, 1992. The peak discharge...
Assessing the True Value of Flood Control Reservoirs: The Experience of Folsom Dam in the February 1986 Flood
Over the last 40 years considerable public investments have been made in large flood control storage reservoirs throughout the U.S. and internationally. These projects were typically designed...
Bank Stabilization with Environmental Features on the Middle Rio Grande
River maintenance on the middle Rio Grande has changed significantly since channel work began in the mid 1950's. Past practices included pilot or relocation channels, vegetation control,...
Two Options for Disposal of Desalination Reject Water
A major problem associated with the use of desalination plants for the production of fresh water is the disposal of the reject water. This water is typically double the salinity of the...
Risk and Uncertainty in Flood Damage Reduction Project Design
The recent emphasis on partnership between the Federal government and local sponsors in the development of flood damage reduction projects has promoted considerable interest in the application...
Modeled Hydraulic and Salt Transport Patterns in the Sacramento-San Joaquin Delta
Modeled hydraulic and salt transport patterns in the Sacramento-San Joaquin Delta have been summarized as the basis for detailed environmental assessment of proposed water management projects...
The EUR Water Station in Rome?Italy
The paper deals the new steel Water Centre realized by ACEA in Rome. The Water Station is destined to manage the water consumption of around 500,000 inhabitants with an output of 3,900...
Relation of Channel Stability to Scour at Highway Bridges Over Waterways in Maryland
Data from assessments of channel stability and observed-scour conditions at 876 highway bridges over Maryland waterways were entered into a database. Relations were found to exist among...
Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...
Storm Water Regulations?Aircraft Deicer/Anti-icers Operations
In 1991, FAA has initiated a storm water program to assist airport operators in complying the EPA Storm Water NPDES regulations. The first FAA project, a survey, addresses present operational...
