In the planning and design of dams and embankments for large multiple-purpose projects, it is usually necessary to evaluate the effect of potentially disastrous extreme events to insure that the proposed developments do not produce an unnecessary increase in the disaster potential. One such case which is being encountered more frequently now involves the design of dams and embankments for projects located downstream from an existing dam.

The Brazos Santiago Inlet (BSI), located at the southern end of Laguna Madre, is a key part of the federal deep-draft Brownsville Ship Channel extending from the Gulf of Mexico to the Port of Brownsville, TX. As part of the Monitoring Completed Navigation Projects program, the focus of this study was to understand the shoaling process in the BSI and to suggest sand management alternatives to reduce inlet maintenance dredging costs. Hydrodynamics and sediment transport were examined for the BSI...

This study develops a mathematical model for the simulation of ships transiting a river under brash ice conditions. The model predicts the growth of the ice on the St. Marys and St. Lawrence Rivers and the subsequent transit times and delays of the ships at traffic levels predicted for the year 2000. Ice removal has been incorporated in the model and various ice removal strategies and removal rates have been investigated. The results of the removal rate study are presented as well as several...

A numerical hydrodynamic study was conducted to compare multiple levee setback alternatives to the base condition (levee without setbacks). The models developed for this study are hypothetical. An unsteady unit hydrograph representing a flood wave was used to perform the simulations. The levee setback alternatives show a reduction in water surface elevation upstream of and at the setback area when compared with the base condition. The overland water velocity increases upstream of the setback...

The behavior of brash ice, its formation and recommended vessel operating procedures are presented. Brash ice behaves as a Mohr-Coulomb solid below a critical strain rate or ship speed. Above this speed, fluidization of the medium occurs and the resistance appears to be that of a viscous, laminar fluid. The optimum operating speed for a vessel in brash is at the viscous threshold, found here to be 0.12 sg.rt of gL) where g (32.2 fS-2) is the acceleration of gravity and L is the length of the...

Between routine navigation dredging operations, the Atchafalaya River Bar Channel (ABC) traps fluid mud, which begins to consolidate. The consolidated mud can begin to block the passage of vessels using the Port of Morgan City, LA. If the mud densities and yield stresses could be kept sufficiently low so that vessels could safely navigate through it, the length of time between navigation dredging could potentially be increased. To demonstrate the feasibility of dragging a large object through...

The improvements would deepen the Entrance Channel from -47 feet (ft) mean lower low water (mllw) to -54 ft mllw. The dredged material is estimated to be 80% sand and does not meet U.S. Army Corps of Engineers guidelines for beach placement. Instead of disposing in the Ocean Dredged Material Disposal Site, nearshore placement is...
