Whenever deepening of a dredged channel is under investigation, a prediction must be made as to the effect of the deepening on the existing dredging requirements. If the deepening is related to advance maintenance dredging rather than to an increase in authorized depth, the prediction becomes even more difficult because the project is allowed to shoal over a wide range of depth. Currently a variety of arbitrary, rule-of-thumb procedures are used for predicting the effect of increased depth on...

Tests were conducted on a 1:36 scale model of a portion of the Guadalupe River. The study was designed to investigate the design of a control weir located at the upstream end of a bypass channel. The bypass channel was designed to pass excess flow and prevent flooding for river flows up to a 100-year event. The original weir design was modified to achieve desired flow distribution and control.

Seasonal water-temperature changes influence stage-discharge and depth-discharge relations in rivers and in conveyance channels and navigation channels where water discharge is constant. The major influence is related to changes in bed configuration which accompanies water temperature changes. Stability analysis provides a theoretical basis for predicting bed-configuration changes, and using the theoretical relations with one empirical coefficient defined from field data, graphical relations...

The dam is a 32 ft. high earth embankment with a drop inlet principal spillway and a vegetated earth channel emergency spillway. The dam is small in size with a significant hazard potential. The dam is in poor condition at the present time. It is recommended that the owner engage the services of a qualified engineer to conduct a detailed study of the seepage at both abutments and the downstream toe of the embankment. There are remedial measures which should be undertaken by the owner.

Our goal is to contribute to a better understanding of basic processes in shallow water and coastal flows, in order to provide better, more physically based parameterizations for coastal models. We seek to understand how high Reynolds number coastal flows interact with boundaries producing tangential stress, dissipation, mixing and secondary circulation. In the future, we intend to compare the field observations with direct numerical simulations.

The entrance channel to St. Andrew Bay, near Panama City, Florida, is subject to the formation of large sand waves. A study was undertaken to determine the extent of the problem, as related to navigation, and to assess possible mitigative alternatives. The inlet was originally constructed in the early 1930's and now must be dredged every 12 to 24 months as a result of the large sand waves which form in the navigation channel. The study considered structural changes to the inlet/jetty system...

The purpose of this technical note is to present some design considerations which benefit dead-end channel flushing. Some of these factors can also be used to improve flushing in existing harbors. Flushing uses the natural energy sources available to remove pollutants and suspended sediments from a waterbody. Construction of dead-end channels should be avoided if possible because they have only one boundary open to flow, thus flushing is limited to this single opening. If it is necessary to...
