Economic Analyses

The U.S. Army Corps of Engineers has pursued continual refinement in the waterway traffic forecasts used in project economic analyses. The multiscenario forecasting of utility steam coal described in this paper, based on the work of Hill & Associates, Inc. (H&A), is a substantial refinement of previous forecasting efforts. H&A prepares 20-year steam coal forecasts on the basis of the interaction of two major linear programming models: the National Power Model (NPM) and the Utility Fuel Economics Model (UFEM). The NPM is a utility industry model that dispatches all electric generating plants in the United States (coal and noncoal), producing forecasts of generation by fuel type within a context of transmission and environmental constraints. The UFEM makes use of highly detailed coal supply data (for approximately 98 coal types) to allocate fuels among plants and units. These two models develop forecasts of coal demand for electricity generation, by type of coal, which were then “mapped” to the waterway. H&A prepared separate forecast scenarios based on three alternative environmental regulatory futures. The first is a continuation of existing law (in this case, the national ambient air quality standards). The second H&A scenario reflects implementation of the administration's Clear Skies Initiative. The final H&A scenario is an implementation of the Clear Skies Initiative without the proposal's severe mercury restrictions.

Debris Removal

In support of the Federal Emergency Management Agency (FEMA), the US Army Corps of Engineers (USACE) managed the removal of Hurricane Katrina storm debris in several states. This paper focuses on the debris removal practices in 16 southern Mississippi counties and the recycling efforts. Debris was removed from public and private property. The debris included vegetation, construction material, electronic waste, vehicles, and vessels. The scope of the USACE mission was expanded several times. The scope within the respective counties varied from vegetation only to the removal of every eligible form of debris. The recommendations proposed should enhance recycling efforts during future debris removal missions.

Control Purpose

Abstract Martis Creek Dam, located in the Truckee Basin north of Lake Tahoe, CA, was initially rated as one of the U.S. Army Corps of Engineers’ highest risk dams in the United States. While the dam has performed its flood control purpose, a history of excessive seepage during even moderate reservoir levels has prevented it from also fulfilling its potential water storage function. During seepage and seismic studies to assess and mitigate deficiencies, high-resolution light detection and ranging (LiDAR) data were obtained. This imagery provides an unprecedented representation of the ground surface that allows evaluation of geomorphology even in areas with a dense vegetation canopy. At Martis Creek Dam, this geomorphic analysis resulted in the recognition of a previously unknown and through-going lineament between the spillway and dam embankment. This feature extends to the southeast, where several lineament splays are exposed on the East Martis Creek Fan. These lineaments were subsequently explored by paleo-seismic trenching at two locations and confirmed as faults with Late Quaternary to Holocene displacement. Faulting was confirmed in both trenches as unique splays of a fault zone with several feet of apparent normal (vertical) slip and an unknown magnitude, but a potentially significant, strike-slip component. Faulting was observed near the ground surface in both cases, and multiple fault events (a minimum of two) are interpreted as at least latest Pleistocene in age, and probably active in the Holocene.

Economic Analyses

This chapter traces the history of cost–benefit analysis in the United States bureaucracy from the 1920s until about 1960. It is not a story of academic research, but of political pressure and administrative conflict. Cost–benefit methods were introduced to promote procedural regularity and to give public evidence of fairness in the selection of water projects. Early in the century, numbers produced by the Army Corps of Engineers were usually accepted on its authority alone, and there was correspondingly little need for standardization of methods. About 1940, however, economic numbers became objects of bitter controversy, as the Corps was challenged by such powerful interests as utility companies and railroads. The really crucial development in this story was the outbreak of intense bureaucratic conflict between the Corps and other government agencies, especially the Department of Agriculture and the Bureau of Reclamation. The agencies tried to settle their feuds by harmonizing their economic analyses. When negotiation failed as a strategy for achieving uniformity, they were compelled to try to ground their makeshift techniques in economic rationality. On this account, cost–benefit analysis had to be transformed from a collection of local bureaucratic practices into a set of rationalized economic principles.

The Impact

In 1974 Public Law 93-251 authorized the estaablishment of the Big South Fork National River and Recreation Area (BSFNRRA). Included were approximately 125,000 acres of portions of a five county area in southeastern Kentucky and north central Tennessee consisting of the Big South Fork River, its tributaries, gorge, and adjacent rim area. Original plans called for the gorge area to remain in its undeveloped state and for the rim area to be developed with lodges, campgrounds, overlooks, trails, and picnic areas. The acquisition of land and the design and construction of roads and facilities were among the responsibilities of the United States Army Corps of Engineers, with the National Park Service assuming responsibility for management once the BSFNRRA is officially established.

The Individual

The mechanism of joint efficiency for roller-compacted concrete (RCC) pavement joints and cracks is affected primarily by aggregate interlock or friction at the vertical interface of the joint. Current U.S. Army Corps of Engineers design procedures for RCC pavements make the conservative assumption that no joint efficiency is achieved at RCC pavement joints and cracks. The purpose of this study was to determine the degree of joint efficiency achieved at RCC pavement joints and cracks; to determine the factors that affect the joint efficiency, and to what degree; and to develop a regression model to predict the joint efficiency using those factors. The heavy weight deflectometer (HWD) and other devices were used to conduct nondestructive joint efficiency tests at 12 different RCC pavement sites around the United States. The joint efficiency results ranged from 22 percent to 89 percent, depending on the type of joint or crack tested. The joint efficiencies decreased significantly with increasing crack width, crack spacing, and decreasing temperature. Cores were taken from some of the sites, and crack width measurements with depth indicated little evidence of crack skewing. The HWD load magnitude significantly affected the joint efficiency, and the individual effects of slab thickness and modulus of subgrade reaction did not appear to be significant from observation of the data. A regression was developed that predicts the joint efficiency of RCC pavement joints or cracks, with an R2 of 62 percent.

Two basic methods of surveying by satellite are possible: that of photographing a satellite against the star background and that of range measurements from ground stations to the satellite. The latter method, which is used by the United States Army Corps of Engineers in its SECOR program, is described in this paper. With the SECOR method, distances are measured simultaneously from four ground stations to a satellite equipped with a transponder system. Results of SECOR tests are given and sources of error are discussed.

Delivery Services

In New South Wales (NSW), Australia, awareness of coastal erosion and shoreline recession had its genesis in the late 1920s when storms damaged houses at Collaroy one of Sydney’s northern beaches (Figure 1). At about the same time the Coogee “Fun” Pier, located on a southern Sydney beach and built between 1924 and 1928, was so damaged by wave attack that the remains had to be removed in 1934. Again in 1945 a new seawall at Cronulla, another southern Sydney beach, was damaged beyond repair and at the same time more houses were lost at Collaroy. This was followed in 1967, 1974, and 1978 by major erosion events that threatened both houses and high-rise buildings at Collaroy, resulted in the loss of houses at Bilgola, a northern Sydney beach and in 1978 the loss of houses at Wamberal, 46 km north of Sydney Harbour (Table 1). Unlike the United States of America (USA) where coastal management comes under both federal and state jurisdictions, in Australia it is the province of the governments of each of the states. The federal government does provide some aspirational guidance, but not significant legislative or financial support. There is also no equivalent to the U.S. Army Corps of Engineers to provide project delivery services. In Australia, the states devolve delivery down to local councils through Acts of Parliament and formal policies that can also have legislative force. However, the failure of the State of NSW to provide all the legislative tools necessary to effectively manage coastal matters at a local council level results in coastal management being abdicated rather than delegated by the state, particularly in relation to private development.
