 | In 1988, a ship discharged its ballast water into Lake St. Clair, Michigan, releasing billions of organisms that it had taken on at a freshwater port in Europe. In the ballast were the larvae of a freshwater mollusc, the zebra mussel (Dreissena polymorpha). This small mussel is usually no more than 5 cm long with characteristic zebra-like stripes (Figure 1). The zebra mussel is native to the Caspian Sea and ... |

|
 | Grade control structures (GCS) are an important facet of the broad effort directed at controlling erosion in flood-control channels that have erodible bed and banks. The annotated bibliography describes published studies of numerous hydraulic structures that have been studied and used for grade control. The bibliography contains 112 citations in addition to a brief discussion of published information available to the GCS designer. |

|
 | This report describes a data base which contains descriptions of navigation lock studies conducted by the Corps of Engineers during 1937-1984. The data base identifies measured quantities, lock features, and a complete bibliography of reports. Data base maintenance and management are automated by means of computer software. |

|
 | A finite difference scheme is used to determine the flow rate through the culverts and water surface elevation in the chamber during a lock operation. The program is written in G635 time-share series, FORTRAN IV, and is part of a Conversationally Oriented Real-Time Program-Generating System (CORPS). The program consists of a main program, three function subprograms, and six subroutines. |

|
 | This study contains a brief literature survey and limited experimental data regarding the water-surface contours for supercritical flow in a steep converging chute. Items relevant to design of the chute sidewalls are described, and the development of a computer model for chute design is suggested. The author also suggests that a horizontal transverse water surface cannot be obtained unless parallel sidewalls are used and that for a converging chute, the ... |

|
 | The following four separate series of prototype tests at Old River Low-Sill Control Structure are presented in this report. (1) High-flow vibration tests (4-5 April 1973), comprised of acceleration measurements, were made to determine the magnitude of the vibration of the structure under higher than normal flows. (2) Vibration monitor tests (16 April-1 June 1973), comprised of acceleration measurement, were made during a period in which the structure was not ... |

|
 | This report presents data obtained during prototype tests concerned with the performance of the 110- by 800-ft lock at Barkley Lock and Dam project, Cumberland River, Kentucky. Prototype measurements are continuous records of the following: (a) pressures at 22 locations in the lock culvert system; (b) valve opening patterns; (c) valve leaf pressures and accelerations; (d) water-surface oscillations and elevation; (e) hawser forces and motion of a nine-barge tow moored ... |

|
 | The report presents data obtained during prototype tests concerned with the vibration of a 106-3/4-in.-diam Howell-Bunger valve at Summersville Dam, Gauley River, W. Va. Prototype measurements include both dynamic and time-averaged values of pressures in the flow and strain at locations on the valve structure. Transverse, vertical, and peripheral accelerations were measured at the downstream end of the valve cone. The data were recorded simultaneously on analog magnetic tape and ... |

|
 | The report is concerned with the unlined diversion tunnel that was used to draw down Long Lake to expose the proposed location for an unlined power tunnel to be constructed as part of the Snettisham project about 28 miles southeast of Juneau, Alaska. The object of the study was to compile project data pertaining to diversion tunnel geometry, lake tapping flow characteristics, and the resultant lake drawdown. These data will ... |
