One of the consequences of the Missouri Basin development program will be the virtual obliteration of the Missouri River between Yankton, South Dakota, and the Montana-North Dakota line. The lakes to be created by the various dams proposed or under construction by the Army Corps of Engineers will inundate all but short stretches of the terraces on which are situated literally hundreds of fortified and unfortified earth-lodge villages and other, earlier, occupational sites. Situated near the northern limit of agriculture but heavily populated by sedentary, horticultural people for a period of several hundreds of years, this anthropologically fascinating area has been barely touched scientifically.

This US Army Corps of Engineers (USACE) National Regional Sediment Management Technical Note (RSM-TN) documents the effects of increased sediment loading to the Missouri River on bed elevations in the lower 498 miles. This was accomplished using a one-dimensional (1D) HEC-RAS 5.0.7 sediment model.

And Control

U.S. Army Corps of Engineers (USACE) guidance, Engineering Technical Letter 1110-2-563, was developed for the design of navigation structures subject to barge impact loading. The new guidance was developed with the use of the results from full-scale experiments conducted under the Innovations for Navigation Projects Research and Development Program. An empirical impact force model was derived from the experimental data, and probabilistic procedures were developed to assist with the design and analysis of navigation structures for impact loads from transiting vessels. Uncertainties in loadings due to a wide range of events from both natural and human sources are crucial in the design of these critical structures. These uncertainties are defined in terms of the distributions for impact angles, velocities, and tow masses, as well as the need to account for loss of power and control events. The methods developed in the guidance for the design and analysis of these structures are focused on defining the return periods for the usual, unusual, and extreme loads for the navigation structures. An example of the probabilistic procedures developed in the guidance is highlighted for the design of an upper guide wall at a navigation project.

The Us

The Missouri River is the longest river in North America and flows from the semi-arid western states to the relatively moist Midwest. An integrated system of large reservoirs, constructed in the mid-20th century, provides important water storage, hydroelectricity and flood control benefits. This system has been managed by the US Army Corps of Engineers which has traditionally followed its original mandate to support navigation and flood control. As water uses and societal values have evolved, the management of the river has slowly evolved, and the Army Corps of Engineers has adopted adaptive management to incorporate biological uncertainties into its decision-making. Other evolution, including the incorporation of economic incentives into water management, has failed to occur.

In the last few years, we have had the opportunity to study a number of prehistoric Caddo Indian sites in the Ouachita Mountains of southwestern Arkansas through conducting archeological surveys of more than 2700 acres at three lakes constructed and managed by the U.S. Army Corps of Engineers, Vicksburg District. The three lakes are DeGray Lake on the Caddo River, Lake Ouachita on the Ouachita River, and Lake Greeson on the Little Missouri River. Our purpose in this article is to summarize the archeological character of the prehistoric Caddo sites in these three different parts of the Ouachita Mountains. We focus in particular on the material culture record of these prehistoric Caddo settlements—especially on the ceramic sherds found on them—and discuss when these sites may have been occupied by Caddo peoples.

<em>Abstract</em>.—As authorized by the Flood Control Act of 1944, the Army Corps of Engineers operates six large earthen dams in Montana, North Dakota, South Dakota, and Nebraska on the main stem of the Missouri River. The six reservoirs make up the largest reservoir system in the United States and are used for flood control, navigation, irrigation, hydropower, water supply and water quality, recreation, and fish and wildlife.

Three new hopper dredges of different sizes and mission performance are currently under construction for the U. S. Army Corps of Engineers. This paper describes the particular features of the dredges that constitute advances in the state of the art, and reviews the philosophy behind their design. In addition, the author demonstrates how this new dredge fleet, though smaller than earlier fleets, will improve the Corps' capability, for both civilian and military purposes, to maintain all U. S. coastal waterways as well as locations overseas that are of interest to the United States. Finally, damage stability requirements and noise abatement specifications are treated in separate appendices.
