Indian River Inlet: Is There a Solution?
Man-made changes at Indian River inlet, Delaware, have occurred over the past 6 decades. During this period the tidal prism of the Indian River-Rehoboth Bays system has increased along...
Hydraulic Modeling of Fish Screens
Hydraulic model studies coupled with available knowledge of fish behavior can be important component in the development of fish-screening systems. To reproduce in a model the flow field...
Fish Screen Developments, Columbia River Dams
This paper describes developments to date for a fish diversion and bypass system being tested for two Columbia River dams. Because of the concern for the negative impacts of screen systems...
Hydraulic Aspects of a Low-Velocity, Inclined Fish Screen
The Potter Valley Hydroelectric Project diverts up to 310 cfs from Van Arsdale Reservoir on the Eel River in north-central California and delivers it to Potter Valley for power production...
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...
Urban Storm Water Instrumentation: a Field Observation
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...
Gully Intrusion on Reclaimed Disposal Sites
A three-phase gully erosion study was initiated at the Engineering Research Center of Colorado State University, in cooperation with the U.S. Nuclear Regulatory Commission. The objective...
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...
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...
Modeling the Tides of Massachusetts and Cape Cod Bays
