Improved native grasses and establishment methods for use on military training lands by A. J Palazzo( )

2 editions published in 2003 in English and held by 221 WorldCat member libraries worldwide

The objective of this project was to develop more wear-resistant plants and evaluate the relationships between military training and plant injury, regrowth, and wear-resistance. Through plant breeding, we were able to improve traits related to resiliency and establishment in introduced and native species of rangeland grasses. We selected for early spring growth, increased seedling vigor, improved tiller and rhizome development after disturbance, and resistance to abiotic and biotic stresses. Our improved plant materials will be ecologically compatible at the military sites because they were developed from collections of species native to or previously seeded at these sites. We made advances in relating molecular markers to plant characteristics and in using DNA fingerprinting techniques to characterize genetic diversity. We used markers to identify species and plants that can grow better at low temperatures. We now have the tools to assess the genetic differences and similarities in commercial and natural seed sources, enabling land managers to select seed sources that will ensure genetic compatibility with existing populations. Our tank traffic studies showed that naturalized, introduced species are more tolerant and recover more rapidly under repeated tracking than native plants. However, two improved native species, western wheatgrass and Snake River wheatgrass, showed promise as stabilization species because of their ability to colonize damaged areas. Our studies on what we call "ecological bridges" confirm that we can select seed mixtures that will establish more rapidly than all-native mixes and will ultimately lead to healthy and persistent stands of native plants. The species in the seed mixtures and the equipment needed are readily available, and the seeding can be done in one application, thus saving money. Our improved germplasm will make these seeding mixes even more desirable

Periodic inspections of Kahului and Laupahoehoe breakwaters, Hawaii : armor unit monitoring for period 1992/93-2001 by Robert R Bottin( Book )

3 editions published in 2002 in English and held by 128 WorldCat member libraries worldwide

Selected coastal navigation structures are periodically monitored under the "Periodic Inspections" Work Unit of the monitoring Completed Navigation Projects Program. Such monitoring is done to gain an understanding of the long-term structural response of unique structures to their environment. Periodic data sets are used to improve knowledge in design, construction, and maintenance of both existing and propose coastal navigation projects. The Kahului Harbor breakwaters and the Laupahoehoe boat-launching facility breakwater, HI, were nominated for periodic monitoring by the U.S. Army Engineer District, Honolulu. The positions of the above-water, concrete armor units (tetrapods, tribars, and/or dolosse photogrammetric analysis. The structures were revisited in 2001 to determine changes that had occurred. Results indicated that some armor units had moved along the seaward quadrant of the head of the Kahului east breakwater. These units were intact, however, and are still functional. Armor unit movements on the Kahului west breakwater and the Laupahoehoe breakwater were minimal. A detailed inventory of broken armor units on these structures was obtained. The sites will be revisited in the future and the long-term structural response of the structures to their environment will continued to be tracked. These data sets will facilitate engineering decisions concerning whether or not closed surveillance and/or repair of the breakwaters might be required to reduce their chances of failing catastrophically. The periodic inspection methods developed and validated for the Hawaii breakwaters may also be used to gain insight into other Corps structures
Navigation conditions in lower lock approach of Ice Harbor Lock and Dam, Snake River, Washington by Howard Park( Book )

2 editions published in 2002 in English and held by 117 WorldCat member libraries worldwide

Possible construction of facilities to improve passage of juvenile and adult migratory fish at Ice Harbor Lock and Dam on the Snake River, Washington, caused concern over the impacts to navigation especially in the lower lock approach. A 1:55-scale physical model of the project was used to help identify these impacts. Navigation conditions in the lower lock approach were determined for various discharges and barge configurations of rock dikes placed in the lower lock approach. The study revealed that the installation flow deflectors at Ice Harbor Dam caused adverse impacts to navigation in the lower lock approach. An intense eddy formed near the downstream guard wall, and the angle magnitude of the crosscurrent in the lower lock approach were larger than those with the no-deflector conditions. Several alternatives included the placement of four, 40-ft-diam circular cells, 120-ft on center, located downstream, parallel, and riverward of the lower guard wall
Salinity changes in Pontchartrain Basin Estuary, Louisiana, resulting from Mississippi River-Gulf outlet partial closure plans with width reduction( Book )

1 edition published in 2002 in English and held by 113 WorldCat member libraries worldwide

The Mississippi River-Gulf Outlet (MRGO) consists of a ship channel 36 ft deep and 500 ft wide, extending approximately 76 miles from the juncture of the Inner Harbor Navigation Channel and the Gulf Intracoastal Waterway in New Orleans, LA, to the -38 mlw (mean low water) -ft contour in the Gulf of Mexico, The purpose of the MRGO is to provide a deep-draft channel to the Port of New Orleans Inner Harbor Facilities. Since the MRGO's completion in January 1968, saltwater flux from the MRGO through direct connections to Lake Borgne and the Gulf Intracoastal Waterway has contributed to an increase in the salinity concentration of the lakes and Biloxi Marshes. This report presents the results of a numerical mode investigation used to predict average salinity changes that will occur in the Lake Pontchartrain Basin as a result of varying levels of depth and width closure of the MRGO below Lake Borgne. This report follows a previous study, ERDC/CHL TR-01-14, that modeled depth closure alone, which produced very low changes in salinity

Study of navigation channel feasibility, Willapa Bay, Washington by Nicholas C Kraus( Book )

6 editions published between 2000 and 2002 in English and held by 42 WorldCat member libraries worldwide

This report represents results of Phase II of a study performed for the U.S. Army Engineer District, Seattle, to determine the technical feasibility of maintaining a reliable bar or entrance navigation channel into Willapa Bay, Washington. The study was authorized by the Seattle District in cooperation with the Port of Willapa Harbor under a Partnering Agreement. The Phase I study was an intensive effort to understand the physical processes at the study site, collect data, and establish numerical simulation models of the waves and currents at the entrance. Numerous alternatives for creating and maintaining the most reliable entrance channel were also identified and screened. The Phase II study describes the results of ongoing monitoring of the existing natural navigation channel, changes in bathymetry, and refinements to the numerical models. Also included is an application of the monitoring and modeling technology to the entrance channel leading from Willapa Bay to Bay Center, a small fishing harbor. The entrance area of this shallow-draft navigation channel served as a convenient surrogate for improving the predictive technology, as well as advancing understanding of sediment transport processes in the bay and the deep Willapa Bay entrance channel
Roofer : steep roofing inventory procedures and inspection and distress manual for asphalt shingle roofs by David M Bailey( Book )

2 editions published in 2000 in English and held by 40 WorldCat member libraries worldwide

This report gives instructions for using ROOFER procedures for establishing a steep roofing inventory and evaluating the condition of asphalt shingle roofs. ROOFER is an engineered management system designed to help facility managers more efficiently manage their roofing assets and make the best use of roof maintenance and repair dollars. This document includes the standardized information the user needs to divide steep roofs into manageable sections and collect and maintain inventory information. Visual inspection survey procedures, which include distress descriptions, severity levels, measurement criteria and photographs of shingle and flashing distresses, are presented. Procedures for distress density calculations are also provided. Roof inspectors can use this information to objectively determine condition indexes that reflect (1) the ability of the shingles and flashings to perform their function, (2) needed level of repair, and (3) waterproof integrity

Wave breaking on a current at an idealized inlet with an ebb shoal by Jane McKee Smith( )

2 editions published in 2001 in English and held by 34 WorldCat member libraries worldwide

In this report, wave breaking on a current is examined through physical-model measurements in an idealized inlet with a steady ebb current. Wave and current measurements will be used to evaluate wave dissipation models. The goal of the study is to provide the data to develop a dissipation function for wave breaking on a current that is based on integrated wave parameters, is applicable for arbitrary water depths, and is robust. The motivation for these laboratory experiments was to measure wave breaking in typical coastal inlet conditions. The measurements are being used to parameterize wave breaking for application in numerical wave transformation models, e.g., in the steady-state spectral wave model STWAVE. The data collected and analyzed for this study are an extension of the data set collected by Smith et al. (1998) in the same physical model facility. Smith et al. (1998) evaluated and developed dissipation algorithms using these data. It was found that whitecapping formulations, strongly dependent on wave steepness, generally under-predict dissipation. A relationship for dissipation as a function of wave height squared was developed which gave improved agreement between calculated and predicted dissipation compared to other work. The relationship also worked as well as others in modeling the wave height. The data presented in this report include a larger range of incident waves and ebb currents than the previous data set (Smith et al. 1998). These experiments also include an elliptical ebb shoal seaward of the inlet. The shoal induces depth-limited breaking (in addition to the current-induced breaking in the inlet), which is a typical feature of many coastal inlets. Also, an examination of effects of laboratory scaling was performed
Repair and rehabilitation of dams : case studies by J. E McDonald( Book )

2 editions published in 1999 in English and held by 33 WorldCat member libraries worldwide

This study was conducted to identify methods that have been used in the repair and rehabilitation of concrete dams. Information was obtained through literary searches, discussions with project personnel, and visits to project sites. Each case history includes a background of the project, the deficiency that necessitated repair or rehabilitation, and descriptions of materials and methods used in the repair or rehabilitation. When available, the cost of the repair project and the performance of the repair to date have been included. Case histories included in this report cover a range of deficiencies in concrete structures, including cracking, spalling, erosion, leakage, inadequate PMF capacity, expansion resulting from alkali-aggregate reaction, instability, and insufficient storage capacity
Military examples of coastal engineering by Robert L Wiegel( )

2 editions published in 1999 in English and held by 30 WorldCat member libraries worldwide

Coastal engineering is required for military ports and harbors and across-the-beach amphibious operations. Examples are given for operations during World War II, the Korean War, and the Vietnam Conflict, one very large (Normandy, France), and some small. Examples are provided to illustrate that no two beach operations are ever the same and that the effects of nature (storms and swell even in the absence of local storms) are often as important or even more important than enemy action. Both functional and structural design for planning and operations are needed. Past military operations have required coastal data and the development of coastal science and engineering in subject areas such as tidal/current analysis, wave/surf forecasting, surf characteristic estimation (including breaker type), surf effects on amphibious craft, beach characteristic estimation (onshore and nearshore profile, sediments), wave runup and bachwash on beaches, littoral current estimation (including alongshore and rip currents), processes at harbor entrances, beach trafficability, wave diffraction at breakwaters, and wave-induced forces. Some of this is described in context with operational needs. The need for reliable coastal intelligence information is emphasized. Thirty-six illustrations and 68 references are given
Tidal inlet equilibrium area experiments, inlet laboratory investigations by William C Seabergh( )

2 editions published in 2001 in English and held by 30 WorldCat member libraries worldwide

This study was designed to examine the relationship among channel area, tidal period, tidal prism, and maximum channel velocity. Movable-bed model experiments were run to define an equilibrium area for different tidal periods and sediments. The magnitude of the areas measured provided additional data for the relationship of the tidal prism versus minimum channel area in a size range slightly larger than previous laboratory data in the continuum to very large field inlets. These data may help define the tidal prism-minimum channel cross-sectional area relationship in the midrange channel size
