Ground freezing effects on soil erosion of army training lands by Lawrence W Gatto( )

4 editions published in 1997 in English and held by 189 WorldCat member libraries worldwide

Military maneuvers damage vegetation and compact and rut soils on training lands, thereby increasing the likelihood of hillslope runoff and soil erosion. Soil Freeze-Thaw (FT) processes can change the hydraulic geometry and roughness of vehicular ruts and reduce soil compaction, which often partially restores the water infiltration rate that existed before compaction. The efficiency of these FT-induced 'repairs' depends on soil water content and FT intensity. Initial tests showed that: (1) an experimental soil bin designed and constructed for rut experiments allows acceptable simulation of field soil FT, and (2) the hydraulic geometry of a rectangular rill in a fine silt soil with an initial volumetric water content of 36% changes dramatically due to rill sideslope slumping during thaw. Future experiments will compare differences in the response of natural rills and vehicular ruts to FT-induced soil failure, and investigate the effects of FT on soil erodibility and the influences of snow cover on soil erosion processes in the spring

FREZCHEM2 : a chemical thermodynamic model for electrolyte solutions at subzero temperatures by Mikhail V Mironenko( )

4 editions published in 1997 in English and held by 175 WorldCat member libraries worldwide

This report documents a Fortran version of a chemical thermodynamic model for aqueous electrolyte solutions at subzero temperatures, FREZCHEM2, which is a further development of the FREZCHEM model. The model uses thermodynamic data of Spencer-Moller- Weare that permit the calculation of chemical equilibria in the Na-K-Ca-Mg-Cl-S04-H2O system between -60 and 25 deg. C at atmospheric pressure. It applies the Gibbs energy minimization method for chemical equilibrium computation combined with Pitzer equations for activity coefficients and water activity calculation. phases

Ice action on riprap : small-scale tests by D. S Sodhi( Book )

5 editions published in 1996 in English and held by 121 WorldCat member libraries worldwide

We conducted 35 small-scale experiments to assess the damage on riprap-covered banks by ice shoving. A review of literature on this subject revealed very litte experience or guidance available for the design of riprap in the cold regions, where presence of moving ice can cause substantial damage too riprapped bank. During the experimental program, we changed the slope of the model riprap bank, the size and the mix of rocks, and the thickness of model ice sheets. Results of these tests are presented in terms of measured horizontal and vertical forces, outcome of interaction as pileup or ride-up events, and damage to the model riprap bank. From the observations made during the tests, the damage to the riprap appears to take place during pileup events, because the incoming ice sheet is forced to go between the riprap and the piled-up ice, bringing with it rocks from the bottom to the surface of an ice pile. To sustain no damage to the riprapped protective layer, maximum rock size (D100) should be twice the ice thickness for shallow slopes and about three times the ice thickness for steeper slopes

Roof blisters : cause and cure by C. J Korhonen( Book )

2 editions published in 1995 in English and held by 100 WorldCat member libraries worldwide

Blisters are a major problem of built-up roof membranes. They are caused by voids built into the roof during construction. They develop into the characteristic dome-shaped humps by a breathing action driven by thermal cycling. A small pressure relief vent was patented by CRREL as a cost-effective way to repair blisters. Though these vents cannot prevent blisters from forming, they can lengthen a roof's service life by repairing the blisters before they break. Two demonstration projects were conducted to transfer the blister vent technology to the military community. Most participants in the demonstration projects found the vent easy to use and that it performed as designed. The main objection to the vent was its price. (MM)

Ice jam flooding on the Missouri River near Williston, North Dakota by James L Wuebben( Book )

3 editions published in 1995 in English and held by 75 WorldCat member libraries worldwide

This investigation focused on ice related flooding along the Missouri River, just below the confluence with the Yellowstone River near Williston, North Dakota. This area is at the upper end of Lake Sakakawea. With the closure of Garrison Dam in 1953, Lake Sakakawea began filling, reaching operational levels in 1965. Changes in the hydraulics, sedimentation and ice regime of the Missouri River caused by the impoundment have led to an increase in the potential for overbank flooding. This report describes the ice regime assessment that was conducted to characterize ice jam flooding, the development of a method to predict the potential for ice jam occurrence and severity, and potential flood mitigation measures

Antifreeze admixtures for concrete by Cold Regions Research and Engineering Laboratory (U.S.)( Book )

6 editions published in 1997 in English and held by 23 WorldCat member libraries worldwide

The goal of this project was to develop a chemical admixture that would reduce the need for wintertime thermal protection of freshly placed concrete. Chemicals were investigated for their ability to promote strength gain in concrete cured below 0 deg C. The project was carried out in five phases. Phase 1 evaluated existing and new admixtures. Phase 2 measured the effect of promising chemicals on concrete properties. Phases 3 and 4 tested the practicality of using the new technology/admixture in the field. Phase 5 disseminated the findings through an Army conference and through the development of this report, in addition to normal W.R. Grace advertising channels. Laboratory strength tests established that two prototype admixtures were capable of protecting concrete down to -5 deg C. Results from other laboratory tests show that the chemicals pose no harm to the concrete or embedded ferrous metals. Concrete containing the prototype admixtures passes standard freeze-thaw tests, does not shrink unusually, does not contain harmful alkalis, and does not produce irregular hydration products. Field tests clearly demonstrated that working with these new admixtures requires no new skills. The concrete can be mixed at lower temperatures, saving energy. The admixtures are easily dosed into the mixing trucks, as is normal practice today, and concrete is finished in the usual manner. Estimates show that the two prototype admixtures can extend the construction season by as much as three months in the contiguous United States. The prototype has proved that low-temperature admixtures are possible. The industry partner sees the need to develop admixtures that will work to -10 deg C before going commercial with this technology
The effects of temperature on germination of eleven Festuca cultivars by A. J Palazzo( Book )

4 editions published in 1997 in English and held by 21 WorldCat member libraries worldwide

Many studies have shown that water potential at planting affects the germination rate and final germination of Festuca cultivars. Limited information is available about the extent of variability in temperature-dependence of germination among different Festuca cultivars. Our objective was to study germination at five temperatures for a wide range of Festuca cultivars. Festuca seeds were screened for germination during 28 days in polyethylene growth pouches held at constant temperatures of 10, 15, 20, 25, or 300C. The germination percentage significantly (p <0.05) increased as the temperature increased from 10 to 150C, when averaged across the cultivars, and decreased thereafter. The cultivar "Clemfine" tall fescue (Festuca arundinacen Schreb.) had the greatest germination percentage, and "Arctared" red fescue (Festuca rubra L.) had the least when averaged across the five temperatures. Conversely, the average time to germination (Atg) was greatest at 100C and least at 300C. Reaching a germination level of 80% or more of the seeds required 14 days at 100C, 9 d at 150C, 8 d at 200C, and 7 d at 25 or 300C. Base temperatures required for germination of Festuca species were 3.20C for rapid germinators, 3.6 to 60C for medium germinators, and 4 to 60C for poor germinators. Heat units (growing degree-days>100C) calculated for the rapid germinators were 1290C-d, 120 to 1400C-d for medium germinators, and 135 to 1910C-d for the poor germinators. Germination decreased as heat units were increased. The Atg and heat unit regressions explained
Improved native grasses and establishment methods for use on military training lands by A. J Palazzo( Book )

2 editions published in 2003 in English and held by 20 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

The state of the art of modeling millimeter-wave remote sensing of the environment by Kevin O'Neill( Book )

3 editions published in 1996 in English and held by 6 WorldCat member libraries worldwide

A survey was undertaken of models for millimeter-wave (MMW) scattering and emission from environmental features, particularly in the vicinities of 35 and 94 GHz. The ultimate objective was to identify models suitable for current or near-future application in scene generation. The ideal model would be based on first principles, would be readily available in facilitated software, and would have reasonable requirements in terms of computational resources and input parameters. At MMW frequencies, these requirements push the frontiers of current science and technology. In most applications, one must accept as a first approximation the approaches currently under development in research settings. This report reviews the basic methods and approaches underlying all available models in terms of volume scattering, treatment of surfaces and transitions, and the development of statistical quantities from rational physics. Very rough surfaces, locally steep surface slopes, and low-angle incidence can rarely be treated entirely successfully, but recent developments offer the prospect of significant progress. Volume and combined surface-volume scattering and emission models are reviewed for application to land, water, vegetation, snow, and ice environments. Most are essentially works in progress, with theory and validation currently building from earlier work at C and X bands. Very sound capabilities are available for treatment of common atmospheric features, with recent progress in modeling more complex meteorological events. Limiting consideration to truly available codes, a list is provided for each of the above areas of models and their sources. Because it is the most comprehensive and is currently facilitated in terms of software, the MIT EMSARS model is the foremost candidate to serve as a platform for future addition and development
