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 154 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

This report provides details of plans to design, develop, and transition LMS as an integrated computer-based capability, and to test and evaluate this capability for solving specific land and water resource management problems at field sites
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 113 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 109 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 junction of the Inner Harbor Navigation Canal and the Gulf Intracoastal Waterway in New Orleans, LA, to the -38 m1w (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 model investigation used to predict average salinity changes that will occur in the Lake Pontchartrain Basin as a result of varying levels of closure of the Mississippi River-Gulf Outlet below Lake Borgne
Quantitative and landscape approaches to amphibian conservation by Anthony J Krzysik ( Book )
2 editions published in 2000 in English and held by 87 WorldCat member libraries worldwide
Natural resources and wildlife managers for Federal agency lands, including those dedicated to military training and testing missions, must make decisions at multiple scales and with implications that extend far beyond the local boundaries of the land the managers are responsible for. Although landscape management at the local level is still as important as ever, current perception for long-term ecological sustainability requires regional contexts and conservation efforts. This document contains three peer-reviewed chapters from Status and Conservation of Midwestern Amphibians, M.J. Lannoo, editor, published by the University of Iowa Press in 1998. These chapters provide quantitative guidance and landscape perspectives to military land managers. The first chapter describes a very fundamental approach to coarse-grained classification of ecosystems on a regional or continental basis and classifying taxa within the ecosystems. The second chapter provides guidance to novice and experienced field biologist for designing and implementing ecological assessment or monitoring programs, and identifies important principles and issues in experimental design, field data collection, data management, and statistical analysis. The third chapter provides an introduction to the complex and valuable technologies and applications of Geographic Information Systems (GIS), cartography, landscape ecology and its metrics, and spatial modeling
UV-VIS spectroscopy of 2,4,6-trinitrotoluene-hydroxide reaction [final report] by Deborah R Felt ( Book )
2 editions published in 2002 in English and held by 51 WorldCat member libraries worldwide
Contamination of groundwater, surface water, and soil by explosives has occurred at military sites throughout the world as a result of manufacture of explosive compounds, assembly of munitions, and deployment of explosives containing devices. As a result of the adverse effects of explosives on humans and environmental receptors, a low-cost means of decontaminating explosives and energetics contaminated areas is needed. Base-induced transformation of explosives shows promise as a rapid, low-cost technology for detoxifying explosives in soil and water. To understand the reaction mechanism, a reaction mixture of 2:1:1 (water: 100 ppm 2,4,6-trinitrotoluene (TNT): 1N KOH) was analyzed by ultraviolet-visible (UV/VIS) spectrometry from 190 to 1,100 nm. Time course measurements were conducted at 25, 20,15, and 12 C.A factor analysis program was used to analyze the spectral data. Principal component analysis indicated that six principal components explained the spectra to within experimental error, with four factors explaining the majority of the variance. Test spectral vectors for four components were developed, including TNT, two intermediates, and the final product, and tested against the abstract vectors. Two possible reaction mechanisms were suggested and tested to explain the spectral data

Diffusive and kinetic fluxes of phosphorus from sediments in relation to phosphorus dynamics in Lake Pepin, Upper Mississippi River by William F James ( Book )
1 edition published in 1999 in English and held by 28 WorldCat member libraries worldwide
Over a 3-year period (1994-96), suspended seston and phosphorus (P) dynamics were examined in the Upper Mississippi River (UMR) and naturally impounded Lake Pepin, with special attention to external and internal P loading processes that may be contributing to deteriorating water quality conditions. The Minnesota River accounted for most of the annual and summer suspended seston (^81 %) and total phosphorus (^44 %) load, while the Metropolitan Wastewater Treatment Plant (Metro Plant) accounted for ^18 % of annual soluble reactive phosphorus (SRP) loading to the UMR. External loading during the summer of suspended seston, total P, and SRP to Lake Pepin averaged ^30,000/m2/day, and ^60 mg/m2/day, respectively. The lake retained a substantial portion of the summer suspended seston load and was also a sink for total P. While total P concentrations generally declined in Lake Pepin from headwaters to outflow, SRP exhibited a trend of increasing concentration from headwaters to outflow with net SRP export during the summer. These contrasting patterns in total P and SRP indicated the occurrence of internal P loading and/or transformations in the water column of P from particulate to soluble phases. Internal diffusive P flux from profundal sediments, estimated from laboratory incubation systems under different temperature and redox conditions, averaged ^7.5 mg/m2/day during the summer under predominately oxic conditions over all years. Although this oxic rate was high relative to other eutrophic lakes, it accounted for <15 percent of both the external total P and SRP loads to Lake Pepin. It did, however, account for 30 to 56 percent of the net SRP export from the lake during the summer. Sediments in Lake Pepin also had a high equilibrium P concentration (EPC = 0.162 mg/L +/- 0.018 S.E.) and native adsorbed P pool (NAP = 0.178 mg/g +/- 0.058 S.E.) at equilibrium
Integration of the Hydrologic Simulation Program-FORTRAN (HSPF) watershed water quality model into the Watershed Modeling System (WMS) by Patrick N Deliman ( Book )
1 edition published in 1999 in English and held by 27 WorldCat member libraries worldwide
The integration of the watershed water quality model Hydrologic Simulation Program-FORTRAN (HSPF) into the Watershed Modeling System (WMS) was initiated as part of an overall goal of the Water Quality Research Program to provide water quality capabilities within the framework of a comprehensive graphical modeling environment for conducting hydrologic and water quality analysis. The WMS interface creates a way for the user to input a multitude of parameters into the input file and then to run HSPF to get the required output. The input parameters are linked to all the tools within WMS, including automated basin delineation and parameter definition using a graphical user interface. The objective of the interface developed in WMS is to provide graphical representation of HSPF data, as well as automate the definition of many of the required parameters. Many of the basic variables required for HSPF input are computed as part of WMS's basic functionality; additionally, specialty functions have been added to WMS to enable the usage of HSPF directly with data output from WMS. This report describes the initial linkage of HSPF into the WMS
Wave breaking on a current at an idealized inlet with an ebb shoal by Jane McKee Smith ( Book )
3 editions published in 2001 in English and held by 27 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
Marine ice atlas for Cook Inlet, Alaska by Nathan D Mulherin ( Book )
1 edition published in 2001 in English and held by 27 WorldCat member libraries worldwide
Cook Inlet, a 350-km-long estuary located in south-central Alaska, is a region of great importance to the economy of the entire state. Approximately half the population of Alaska resides near its shores, and Anchorage, at its northern end, is the state's largest city and a focus for commerce, industry, recreation, and transportation. Tidal height variations at Anchorage are the second most extreme in the world, exceeded only by those in Canada's Bay of Fundy. Cook Inlet's extreme tidal range and the shallow bathymetry produce extreme tidal currents as well. During winter the marine ice that forms in the Inlet can have a substantial impact on human activities. This report is a compilation of previously published and unpublished information on the climatic, meteorological, oceanographic, and hyrodynamic conditions that influence the marine ice cover in Cook Inlet. Biweekly maps, based on historical conditions from 1984 through 1999, are presented that show the expected concentrations and stages of development of the ice cover. These maps were produced by re-analyzing approximately 675 archived ice charts that were produced by the National Weather Service between 1984 and 1999, using ArcView TM GIS software
DMS : Diagnostic Modeling System by Nicholas C Kraus ( Book )
2 editions published in 2000 in English and held by 23 WorldCat member libraries worldwide
The Diagnostic Modeling System (DMS) is intended to provide a rapid, yet reliable capability for identifying and evaluating navigation channel operations and maintenance (O & M) alternatives based on limited information about the hydrodynamic and sediment- transport conditions at a site. The DMS gives a diagnosis of a problem shoaling area (in contrast to conducting expensive and time-consuming studies), together with guidance for determining possible solutions. The DMS also contains dredging and associated records to document shoaling patterns and measures taken. As a first proof of concept, the methodology of the DMS was applied to investigate a region of increasing sediment shoaling along the Gulf Intracoastal Waterway (GIWW), Matagorda Bay, Texas. Morphological, engineering, and numerical modeling approaches were taken in three parallel paths. The three study methods found that a bird island located near the intersection of the GIWW and Matagorda Ship Channel (MSC) was experiencing significant erosion because of its close proximity to the MSC entrance and strong flood currents. The DMS methodology led to the conclusion that the GIWW should be located several kilometers north of its present location, which would also improve navigation efficiency at the MSC and GIWW intersection
Study of navigation channel feasibility, Willapa Bay, Washington ( Book )
1 edition published in 2000 in English and held by 23 WorldCat member libraries worldwide
This report presents 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, as 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
Tidal inlet equilibrium area experiments, inlet laboratory investigations by William C Seabergh ( )
3 editions published in 2001 in English and held by 22 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
