Environmental analysis of the Upper Susitna River Basin using Landsat imagery( Book )

4 editions published in 1980 in English and held by 108 WorldCat member libraries worldwide

The primary objectives of this study were to 1) prepare a map from Landsat imagery of the Upper Susitna River Basin drainage network, lakes, glaciers and snowfields, 2) identify possible faults and lineaments within the upper basin and within a 100-km radius of the proposed Devil Canyon and Watana dam sites as observed on Landsat imagery, and 3) prepare a Landsat-derived map showing the distribution of surficial geologic materials and poorly drained areas. The EROS Digital Image Enhancement System (EDIES) provided computer- enhanced images of Landsat-1 scene 5470-19560. The EDIES false color composite of this scene was used as the base for mapping drainage network, lakes, glaciers and snowfields, six surficial geologic materials units and poorly drained areas. We used some single-band and other color composites of Landsat images during interpretation. All the above maps were prepared by photointerpretation of Landsat images without using computer analysis, aerial photographs, field data, or published reports. These other data sources were used only after the mapping was completed to compare and verify the information interpreted and delineations mapped from the Landsat images. Four Landsat-1 MSS band 7 winter scenes were used in the photomosaic prepared for the lineament mapping. We mapped only those lineaments related to reported regional tectonics, although there were many more lineaments evident on the Landsat photomosaic

Winter thermal structure, ice conditions and climate of Lake Champlain by Roy E Bates( Book )

3 editions published in 1980 in English and held by 75 WorldCat member libraries worldwide

Winter thermal structure and ice conditions in the land-fast ice cover of Lake Champlain were studied in detail for the winters of 1975-76 and 1976-77. The lake was instrumented to a depth of 8.5 m with a string of highly calibrated thermistors attached to an ice mooring system and connected to a data logger at Shelburne Point, Vermont, during the winter of 1975-76 and at Gordon Landing on Grand Isle, Vermont, during 1976-77. This data logger automatically recorded water temperatures from the surface of the lake though snow, ice and water vertical profiles to the bottom of the lake every four hours. Pertinent meteorological parameters are presented for the appropriate measurement sites during the two winter periods, November '75-April '76, and November '76-April '77. Computations were made of freezing degree days (C) for both winters and correlated with ice formation dates. Predictions of ice growth, using the Stefan equation with an empirical coefficient, were correlated with actual ice growth. Documentation was made of the Lake Champlain Transportation Company's first attempt at wintertime navigation by ferry from Gordon Landing, Vermont, to Cumberland Head, New York, in a land fast ice cover during one of the coldest winters of this century.

Suppression of river ice by thermal effluents by George D Ashton( Book )

3 editions published in 1979 in English and held by 69 WorldCat member libraries worldwide

The ice suppression resulting from discharge of warm water into rivers during winter is analyzed with emphasis on two different cases. In Part 1 the case of a thermal effluent fully mixed across the flow section is analyzed to include the effects of unsteadiness in the effluent temperature and the meteorological variations. The location of the ice edge is determined either by a 0 C water temperature criterion or an equilibrium ice melting analysis. The choice of the applicable criterion emerges naturally from the analysis even though the location of the ice edge may be considerably different when a steady-state analysis is done. In Part 2 the case of a side discharge of heated effluent is analyzed, also in an unsteady manner, and the effects of transverse dispersion are included in the analysis. Comparisons are made in both Parts 1 and 2 to limited field data that are available. (Author)
Effect of temperature on the strength of snow-ice by F. Donald Haynes( Book )

3 editions published in 1978 in English and held by 69 WorldCat member libraries worldwide

Uniaxial compression and tension tests were conducted on polycrystalline snow-ice to determine the effect of temperature on its strength. Test temperatures ranged from -0.1 C to -54 C. Two machine speeds, 0.847 mm/s and 84.7 mm/s were used for the constant displacement rate tests. The compressive strength at -54 C was about one order of magnitude higher than at -0.1 C. The tensile strength at -18 C was about 20% higher than at -0.1 C. The initial tangent and 50% strength moduli are given for the compression tests, while the secant modulus to failure is given for the tension tests. The mode of fracture is discussed and the test results are compared with data from other investigations

On the buckling force of floating ice plates by Arnold D Kerr( Book )

3 editions published in 1981 in English and held by 68 WorldCat member libraries worldwide

The calculation of the largest horizontal force a relatively thin floating ice plate may exert on a structure requires the knowledge of the buckling load for this floating plate. In the published literature on the stability of continuously supported beams and plates, it is usually assumed that this buckling force corresponds to the lowest bifurcation force p sub cr. However, recent studies indicate that, generally, this is not the case, and this report clarifies the situation of floating ice plates. This problem is first studied on a simple model that exhibits the buckling mechanism of a floating ice plate but is amenable to an exact nonlinear analysis. This study shows that, depending on the ratio of the rigidities of the 'liquid' and 'plate', the post-buckling branch may rise or drop away from the bifurcation point. Thus p sub cr may or may not be the actual buckling load. It is also shown that when lift-off of 'plate' from the 'liquid' takes place, the actual buckling load may drop substantially. This study is followed by analysis of a floating compressed semi-infinite plate with a straight free edge, assuming that there is no life-off. It is found that for this case there always exists a buckling load that is lower than p sub cr. According to the obtained results, the value p sub cr should be used with caution as a buckling load for floating ice plates. It is suggested that the buckling load be determined using the post-buckling equilibrium branch of the plate, taking into considertion the possibility of lift-off of the ice cover from the liquid base.
