Abstract: This model study was conducted to evaluate the characteristics of inflow conditions into an existing pump sump that would result with increased discharge capacity due to installation of the three proposed pumps and to develop modifications, if needed, within the confines of the present sump to improve flow distribution to the pump intakes.

A report regarding a filling and emptying system, Walter Bouldin lock, and lock culvert valve for the Coosa River Waterway, Alabama.

From abstract: The Columbia Hybrid Modeling System was applied to the mouth of the Columbia River estuary to evaluate alternatives for reducing navigation channel maintenance dredging.

"This is one in a series of scientific reports documenting the findings of studies conducted under the Interagency Field Verifications of Testing and Predictive Methodologies for Dredged Material Disposal Alternatives (referred to at the Field Verification Program or FVP). This program is a comprehensive evaluation of environmental effects of dredged material disposal under conditions of upland and aquatic disposal and wetland creation."

This report follows the study of the sedimentary and hydraulic processes in Long Island Sound near Green Ledge, Connecticut, and Eaton's Neck, New York with the intention of investigating was to evaluate the effects of aquatic disposal of dredged material on organisms and water quality, including the significance of physical, chemical, and biological factors that influence the rate of disposal site recolonization by benthic animals.

The following report presents the results of a investigation to determine the baseline conditions of the phytoplankton population at the disposal site for future comparison with similar data collected after the disposal of dredged material.

Appendix containing test results of core and grab sample data from Eatons Neck. It accompanies a report on the investigation of the hydraulic regime and the physical characteristics of bottom sedimentation as part of a study to investigate the effects of disposal sites on organisms and the quality of surrounding water.

Appendix containing black and white reflection-profile photos. It accompanies a report on the investigation of the hydraulic regime and the physical characteristics of bottom sedimentation as part of a study to investigate the effects of disposal sites on organisms and the quality of surrounding water.

Appendix containing profile camera photos to accompany a report on the investigation of the hydraulic regime and the physical characteristics of bottom sedimentation as part of a study to investigate the effects of disposal sites on organisms and the quality of surrounding water.

Appendix containing navigation calculations and the the design specifications for buoys to be used in experimental observations at Eatons Neck. It accompanies a report on the investigation of the hydraulic regime and the physical characteristics of bottom sedimentation as part of a study to investigate the effects of disposal sites on organisms and the quality of surrounding water.

Appendix containing black and white photos of flora and fauna at the bottom of Eatons Neck site to accompany a report on the investigation of the hydraulic regime and the physical characteristics of bottom sedimentation as part of a study to investigate the effects of disposal sites on organisms and the quality of surrounding water.
