 | An International Symposium on Hawaiian Stream Ecology, Preservation, and Management was held in Hilo, Hawaii, 1-2 November 1993. The Symposium was cosponsored by the Operations Division of the U.S. Army Engineer Pacific Ocean Division, the U.S. Army Engineer Waterways Experiment Station, and the State of Hawaii Commission on Water Resources Management. The objectives of this Symposium were to bring together scientists, resource managers and planners, special interest groups, and the ... |

| This report provides details for the construction of a hot-bead thermistor current meter which is capable of measuring water velocities on a millimeter spatial scale and for the construction of a compact and accurate calibration system. Hot-bead thermistor current meters can be built with response times of 200 ms capable of measuring velocities between 0.1 and 80 cm s(-1). The construction of a sturdy probe for application in lotic systems ... |

| The effects of minor alterations to the surface of articulated concrete mattress (ACM) blocks, used to protect the banks of the Lower Mississippi River from erosion, were examined with laboratory and field studies. Field studies were conducted at Marshall Point, RM 446.8, Issaquena County, Mississippi, on 18 July 1989 and at False Point Revetment, RM 443.1, Madison Parish, Louisiana, on 5 July 1990. Rough surfaces created a drag on moving ... |

|
| The software system, TRAFFIC, was developed to provide technical information and literature on the physical effects of navigation traffic, particularly on selected riverine organisms. The TRAFFIC software program has been designed to run on an IBM-PR or compatible microcomputer with a minimum of 256 K of computer memory and type of video card and monitor. TRAFFIC is easy to use and requires no knowledge of computers. Depending upon the program ... |

|
| This document summarizes and discusses recent studies on the value of submersed aquatic macrophytes for macroinvertebrates. Discussion on the effects of macrophytes on benthic invertebrates is followed by sections on the colonization of macroinvertebrates on Potamogeton nodosus and Ceratophyllum demersum. The next parts describe a study on the effects of macrophytes on distribution of zooplankton, the effects of C. demersum structure on macroinvertebrate colonization. The report concludes with a general ... |

|
| Turbulence and wave wash from commercial navigation vessels can resuspend sediments, reverse river currents, and cause water drawdown. These physical effects can stress or kill pelagic fish eggs and larvae, bottom- dwelling invertebrates such as freshwater mussels (Family: Unionidae), aquatic insects, worms, and crustaceans. Impacts of navigation traffic have been studied in the field and the laboratory. In field studies, investigators have measured wave height, drawdown, current reversals, and suspended ... |
