Erosion Protection at Hydraulic Structures: A Report From the Task Committee
In 1991 the ASCE Hydraulics Structures Committee formed a task committee on Erosion Protection at Hydraulic Structures. The purpose of the committee is to determine current practices in...
An Assessment of Fish Entrainment and Impingement Potential for an Offshore Cooling Water Intake in a Tropical Bay
Fish entrainment and impingement potential were assessed for a proposed cogeneration facility on the west coast of Puerto Rico that will withdraw cooling water using offshore intake structures....
Using a Numerical Model to Evaluate Striped Bass Management Scenarios in the Sacremento-San Joaquin Delta, California
Since the mid-1970's, the striped bass, Morone saxatilus, population in the Sacramento-San Joaquin Delta, California has been declining. The primary suspected cause of the decline is associated...
Hydrodynamic Modeling for Channel Barrier Design
A two-dimensional vertically-averaged finite element hydrodynamic model was used at two scales to predict flow conditions for design of a proposed fish barrier: one for the general hydraulic...
Multi Objective Detention Outlet Control Structure
Increasing numbers of stormwater management ponds are being included in the design of urban and rural drainage projects. This is in part due to the environmental outcry to clean up our...
Management of Rice Fields for Wetlands, Water, and Rice Production
The feasibility of managing a portion of the Sacramento Valley's rice fields as wetlands for waterfowl use, storage, and aid in rice straw decomposition was evaluated. Approximately 95%...
Sediment Disposal and Transport in Central SF Bay
The relocation of dredged material from navigation channels in the Francisco Bay is crucial to the movement of deep-draft shipping and shallow-draft recreational vessels. The margins of...
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...
An Empirical Model for the Volume-Change Behavior of Debris Flows
The potential travel down hillsides; movement stops where the volume-change behavior of flows as they travel down hillsides ; movement stops where the volume of actively flowing debris...
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...
