    In: CRREL Report, 80-10
    Description / Table of Contents: A mathematical model of coupled heat and moisture flow in soils has been developed. The model includes algorithms for phase change of soil moisture and frost heave and permits several types of boundary and initial conditions. The finite element method of weighted residual (Galerkin procedure) was chosen to simulate the spatial regime and the Crank-Nicholson method was used for the time domain portion of the model. To facilitate evaluation of the model, the heat and moisture fluxes were essentially decoupled; moisture flux was then simulated accurately, as were heat flux and frost heave in a laboratory test. Comparison of the simulated and experimental data illustrates the importance of unsaturated hydraulic conductivity. It is one parameter which is difficult to measure and for which only a few laboratory test results are available. Therefore, unsaturated hydraulic conductivities calculated in the computer model may be a significant source of error in calculations of frost heave. The algorithm incorporating effects of surcharge and overburden was inconclusively evaluated. Time-dependent frost penetration and frost heave in laboratory specimens were closely simulated with the model. After 10 days of simulation, the computed frost heave was about 2.3 cm vs 2.0 cm and 2.8 cm in two tests. Frost penetration was computed as 15 cm and was measured at 12.0 cm and 12.2 cm in the two laboratory samples after 10 days.

    Call number: ZSP-201-76/30
    In: CRREL Report, 76-30
    Description / Table of Contents: The focus of this investigation was to assess the utility of remote sensing techniques in the study of land use-water quality relationships in an east central Wisconsin test area. The following types of aerial imagery were evaluated for this purpose: high altitude (60,000 ft) color, color infrared, multispectral black and white, and thermal; low altitude (less than 5000 ft) color infrared, multispectral black and white, thermal, and passive microwave. A non-imaging hand-held four-band radiometer was evaluated for utility in providing data on suspended sediment concentrations. Land use analysis includes the development of mapping and quantification methods to obtain baseline data for comparison to water quality variables. Suspended sediment loads in streams, determined from water samples, were related to land use of dfferences and soil types in three major watersheds. A multiple correlation coefficient R of 0.85 was obtained for the relationship between the 0.6-.7 incident and reflected radiation data from the hand-held radiometer and concurrent ground measurements of suspended solids in streams. Applications of the methods and baseline data developed in this investigation include: mapping and quantification of land use; input to watershed runoff models,estimation of effects of land use changes on stream sedimentation; and remote sensing of suspended sediment content of streams. High altitude color infrared imagery was found to be the most acceptable remote sensing technique forthe mapping and measurement of land use types.

    Description / Table of Contents: In order to verify current theoretical equations on ice bearing capacity, a heavily loaded truck was used to make successive passes over two ice bridges. Equipment, weather and the normal problems associated with field work resulted in only one complete breakthrough test. Breakthrough occurred on one bridge with a vehicle weight of 53,630 lb (24,327 kg) and an ice thickness of 17.5 in. (44.5 cm). Since only one test was completed, the conclusions drawn cannot be unequivocal. However, the results do indicate that Nevel's equation for ultimate failure of a floating ice sheet is a good working tool.

    Call number: M 11.0097
    In: Nova Hedwigia / Beiheft, 136
    Description / Table of Contents: The present volume contains 21 papers presented at the Seventh International Chrysophyte Symposium 2008 spanning a broad range of topics on chrysophytes and related heterokont organisms. The contributions include ones on ecology, taxonomy, floristic works, phylogeny and evolution, molecular biology, physiology and paleolimnology. Of special interest are a group of papers that use geometric morphometric analyses to address taxonomic, biogeographic and phylogenetic questions related to chrysophytes and other microalgae. Ecological and floristic contributions include ones on lakes from the polar Ural Mountains, the Mesopotamia region of South America, the Pine Barrens of southern New Jersey, and the Swiss Alps. Gene sequences are used to study hidden diversity in Synura and differences between two geographically distinct Heterosigma isolates, and production of polyunsaturated aldehydes is examined in Thalassiosira. Other contributions include ones on mixotrophy, biofilm dynamics, the recent invasion of Mallomonas pseudocoronata into lakes in Sweden, use of cysts in climate change research, paleolimnology of eastern North American lakes, an evaluation of the age of the Hueyatlaco early man site in Mexico, a comparison of the architecture of Mallomonas scale coverings between modern and 40 Ma specimens and bloom dynamics. Papers outlining the establishment of a Wiki for chrysophyte cysts, an on-line database for Eocene chrysophyte fossils, and ideas f
