Hydraulic Desiltation for Noncohesive Sediment
Sedimentation reduces the useful life of a reservoir. The physical processes of flushing sediment are not well-understood. Flushing processes can be classified into two categories: local...
The Flushing Flow Problem on the Trinity River, CA
Flushing flows are high flow releases designed to remove fine sediment accumulated in river gravels downstream of reservoirs. These releases must be designed to maximize transport of sand-sized...
HEC-6 Modeling of Sediment Management in Lo?za Reservoir, Puerto Rico
Design, Construction, and Performance of a Baffled Breakwater
The Spud Point Marina breakwater is located within Bodega Harbor, a protected embayment on the northern California coast. Waves are attenuated by baffle panels hung between support piles....
Tide- and Wind-Driven Flushing of Boston Harbor, Massachusetts
The flushing of Boston Harbor, a shallow, tidally dominated embayment with little fresh water input, is investigated using a depth-averaged model. The modeled tidal currents exhibit strong...
Impact of Breakwater Removal on Hydrodynamics and Water Quality in Flushing Bay, New York
Hydrodynamic and water quality models were used to simulate the potential effect of removing a breakwater to increase flushing and improve water quality in Flushing Bay, New York City....
Flushing Characteristics for Harbor Planning
A two-dimensional hydrodynamics model was used to understand the circulation and transport patterns in Keelung Harbor, Taiwan. The calculated hydrodynamics information was used to determine...
Dynamic Flushing of Pocket Marinas
The expanding demand for marina space combined with just concerns for the coastal environment has developed an urgent need for methods for evaluation of the flushing characteristics of...
Marina Flushing Along a Structurally Controlled Canal
Evaluation of flushing characteristics of a proposed marina located along a structurally controlled navigable canal is reported. This canal is operated to maintain the water level of Lake...
The Calculation of Flushing Flows for Gravel and Cobble Bed Rivers
Flushing flows are needed to remove fines and sand from a gravel or cobble bed river. A natural stream will have periodic high flows adequate for flushing of fines and sand, but the hydraulic...
Three-Dimensional Model of a Stratified Estuary?St. Andrew Bay System, Florida
A three-dimensional modal is applied to a northwest Florida estuary to provide the initial insights into the circulation and flushing patterns of the system. The model, developed by the...
Sediment Transport Due to Channel Flushing
Blocking of rivers and canals by sediment due to landslides or dumping of waste create problems of upstream flooding and drainage. Experiments are carried out in the present study on flushing...
Application of Hydraulic and Sediment Transport Principles in the Design of Tidal Exchange Structures
This paper presents a procedure for the analysis and design of tidal exchange structures, such as tidal gates and training dikes. In lieu of over generalized theories or complicated modeling...
Hydraulic Design Aspects of the Boston Outfall
The diffuser outfall under design for Boston must have the ability to be purged of seawater upon commissioning or following an accidental flow stoppage. The criteria governing the flushing...
Flushing Flow Analysis Concepts
Many environmentally oriented groups who oppose water resources projects, have conceived various types of flow requirements to supposedly meet a variety of biological purposes in rivers....
Subsidence Control by High Volume Grouting
Mine grouting programs generally fall into two general methods: flushing and grout columns. With the flushing method, the entire mine under the area to be protected is filled. Grout columns...
Simulation and Video Animation of Canal Flushing Created by a Tide Gate
A tide-gate algorithm was added to a one-dimensional unsteady flow model that was calibrated, verified, and used to determine the locations of as many as five tide gates that would maximize...
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
A Proposed Desilting Reservoir System in Taiwan
The paper discusses the design of a desilting system for Nanhwa reservoir, in which the reservoir is divided into two bays; water flows into the forebay for sedimentation and then over...
Physical Habitat Simulation and the Moveable Bed
One objective of an instream flow analysis is to quantify a flow that will maintain the existing channel and/or flush fine material from the bed. Five empirical approaches to determine...
