Object-GAWSER : object-oriented Guelph all-weather storm-event runoff model : phase I, training manual : application of object-oriented simulation to hydrologic modeling by Cold Regions Research and Engineering Laboratory (U.S.)( Book )

1 edition published in 1996 in English and held by 177 WorldCat member libraries worldwide

Hydrologic models are currently used to understand the economic and ecological imacts of hydrologic processes. A new hydrologic model entitled Object-GAWSER was designed using an object-oriented platform to provide new insights into watershed hydrology. Object-GAWSER is a temperature index model that simulates upland watershed hydrology. Object-GAWSER is different from other hydrologic models in that each one of its components can be easily studied to understand its sensitivity to various inputs. First, this report will show how Object-GAWSER can be used to simulate the hydrologic behavior of forested, agricultural, and suburban watersheds. Second, this report will describe how Object-GAWSER was designed
Freeze-thaw processes and soil chemistry by Giles M Marion( Book )

2 editions published in 1995 in English and held by 176 WorldCat member libraries worldwide

This review broadly examines the interactions between freeze-thaw processes and soil chemistry, focusing on (1) the effect of solutes on physical properties such as freezing-point depression, unfrozen water and frost heaving, (2) the effect of freeze-thaw cycles and low temperatures on soil chemistry, and (3) modeling of freeze-thaw processes and chemistry. The presence of solutes causes a freezing-point depression, which increases the amount of unfrozen water in soils. Liquid films on soil particles provide the dominant route for the flow of water and associated solutes in frozen soils. In general, salts reduce the hydraulic conductivity and water flow to the freezing front, which reduces frost heaving. Solute exclusion during freezing leads to supersaturated solutions, which promotes the precipitation of secondary minerals in soils. At the watershed level, ionic concentrations in early melt- waters are often 2-9 times higher than snowpack concentrations. Temperature is the dominant factor controlling decomposition rates, with minimal detectable rates occurring at temperatures as low as -10 deg C; both bacteria and fungi are physiologically active at subzero temperatures. Extracellular enzymes are active in soils at temperatures as low as -20 deg C; this activity is thought to occur in unfrozen water on surfaces of soil particles. Nitrogen mineralization is reported at temperatures as low as 1 deg C and is promoted by freeze-thaw cycles. jg
The winter low-flow balance of the semiarid White River, Nebraska and South Dakota by M. G Ferrick( Book )

1 edition published in 1995 in English and held by 173 WorldCat member libraries worldwide

Low-flow studies ore needed to quantify the effects of water consumption on stream flow, water quality, groundwater resources, and contaminant transport. The low-flow water balance of a river in a cold region is simplified in winter because evapotranspiration is negligible, irrigation water withdrawals and diversions are halted, and precipitation occurs largely as snow, minimizing the spatial arid temporal variability of runoff. We investigated the monthly low-flow water balance of White River (Neb. and S. Dak.) reaches over seven consecutive winters. Water going into or out of storage as ice or melt, obtained with an air temperature index model, can be a dominant component of the water balance. The point estimate method is used to account for parameter uncertainty and variability, providing the mean, variance, and limits of dependent variables such as water storage as ice and inflow from a subbasin. Negative surface water yield from several-thousand-square-kilometer subbasins occurred regularly through the period, indicating a significant flow from the river to the alluvial aquifers. The winter water balance results suggest either a perched river or a coupled surface water-groundwater hydrologic system in particular subbasins, consistent with the field investigations of Rothrock (1942). The winter flow exchange between The surface and subsurface can be used to estimate the annual exchange for both hydrologic conditions
River ice data instrumentation by Roger Lee Kay( Book )

1 edition published in 1997 in English and held by 172 WorldCat member libraries worldwide

Ice processes are capable of causing damage to Corps of Engineers flood control, water control, and navigation projects each year. Monitoring of ice and other physical parameters is done by instrumentation in some instances but is usually done manually. Measurements that require personnel to go on an ice cover can be risky or impossible, depending on the ice cover's stability and the individual's training. This study seeks to identify and rank the field measurements needed during winter conditions and the instrumentation required to make the measurements. Existing and developing instrumentation was evaluated for in-situ and remote sensing capabilities. Methods of transmitting, storing, and retrieving various types of ice data were explored for feasibility and practicality. Recommendations are identified regarding the types of instrumentation, data transmission, and storage methods that need to be improved or developed

Soil Remediation Demonstration Project : biodegradation of heavy fuel oils by Charles M Reynolds( Book )

1 edition published in 1997 in English and held by 167 WorldCat member libraries worldwide

Treatment of oil-contaminated soils is necessary to protect water supplies, human health, and environmental quality; but because of limited funds, cleanup costs are often prohibitive. High costs are exacerbated in cold regions such as Alaska, where spills are often in areas inaccessible to heavy equipment and where there is limited infrastructure. Owing to the lack of infrastructure, widespread fuel distribution systems, and the need for heating in the cold climate, there are numerous small-scale oil spills. Low-cost treatments applicable to small-scale spills are needed. The object of this CPAR project was to examine using cost-effective, on-site bioremediation techniques for heavy-oil-contaminated soil in cold regions. Both heavy-oil and diesel-contaminated soils were used to compare landfarming, a low-intensity treatment, to pile bioventing, a costlier treatment. For each soil-contaminant combination, we compared nutrient additions to a control with no nutrient additions. Under the conditions of this study, landfarming with nutrient additions was as effective for treating diesel-contaminated soil as was bioventing with nutrient additions. For heavy oils, landfarming with nutrients resulted in lower soil concentrations after one year, but differences among treatments were not statistically significant. Because landfarming does not require pumps, electricity, or plumbing, all costs are less than for bioventing. The minimal requirements for infrastructure also make landfarming attractive in remote sites typical of cold regions
RIGIDICE model of secondary frost heave by Patrick B Black( Book )

2 editions published in 1995 in English and held by 163 WorldCat member libraries worldwide

A revised version of an earlier attempt to numerically solve Miller's equations for the RIGIDICE model of frost heave is presented that corrects earlier mistakes and incorporates recent improvements in the scaling factors of ground freezing. The new version of the computer code also follows the concepts of Object Oriented Numerics (OON), which allow for easy modification and enhancements. Analysis of the program is accomplished with the symbolic math program MathCad. A brief sensitivity analysis of the input variables indicates that those parameters that calculate the hydraulic conductivity have the greatest influence on the variability of predicted heaving pressure.

Sealants and cold regions pavement seals : a review by Stephen A Ketcham( Book )

3 editions published in 1995 in English and held by 161 WorldCat member libraries worldwide

A pavement joint seal prevents the passage of liquids into the pavement base and the intrusion of solids into the joint. The primary mechanical requirements of a pavement seal are that it respond elastically or viscoelastically to any movement of the joint without failure and that it withstand indentation of hard objects like rocks. Because pavement joint movements and seal deformations can be large, elastomeric sealants are often used to form seals. Winter conditions are recognized as the most critical for a seal because of the possibility that failure stresses will be reached as the joint opens to a maximum and the material stiffens in response to the temperature reduction. This report reviews the specific problems and requirements that cold climates create for the performance of elastomeric seals. Emphasis is placed on the material response behavior that can lead to failure of a seal. In an attempt to clarity the mechanics of sealant and seal performance associated with low-temperature pavement applications and to address the issue of low-temperature stiffening That should be a dominant factor in the selection of a sealant, this report presents background information on the formulation and mechanical properties of elastomeric seal materials and the structural behavior of field-molded joint and crack seals.

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)
