  • Test method to determine the degree of asphalt stripping from aggregates

    Creator:
    Boudreau, Richard L.
    Abstract:
    Moisture damage has long been recognized as one of the most critical factors influencing the performance of asphalt concrete (AC) pavements. This moistureinduced damage occurs from either the physical separation of the asphalt film from the aggregate or the softening of the asphalt binder within the AC mixture in the...

  • Heat source : stream, river and open channel temperature prediction

    Creator:
    Boyd, Matthew S.
    Abstract:
    Reach defined analysis concentrated on the water temperature change that occurred in a stream/river segment over the course of one full diurnal cycle. Digital thermistors, data loggers and computer model development were utilized in reach analysis to link parameters of the stream system to a specific temperature change. The methodology...

  • Continuous-flow and batch column studies of anaerobic carbon tetrachloride biotransformation on Hanford soil

    Creator:
    Niemet, Michael Richard
    Abstract:
    Continuous-flow and batch experiments were conducted with a column reactor system containing Hanford aquifer material in order to evaluate the potential of in-situ bioremediation of carbon tetrachloride (CT) at Hanford. The effectiveness of benzoate and acetate as primary substrates was considered. Nitrate and sulfate were potential electron acceptors. Transport experiments...

  • Analytical framework for modeling scale-related variabilities in remote sensing

    Creator:
    Chen, Chaur-fong
    Abstract:
    A general analytical framework was established to investigate the scale-related variabilities in remote sensing. The variabilities were studied first by investigating canopy structure, canopy interaction with light, relation between spectral reflectance and plant phenological parameters. The variabilities simulated by the plant model were compared with the actual spectral data acquired...

  • Application of geostatistics to regional evapotranspiration

    Creator:
    Amegee, Kodjo Y.
    Abstract:
    Regionalized variable analysis has been used to study a number of meteorological and hydrological variables including precipitation (Delhomme and Delfinier, 1973), streamfiow (Villeneuve et al., 1979) and hydraulics of groundwater aquifers (Gambolati and Volpi, 1979). In the research work reported in this thesis, an attempt was made to characterize the...

  • Land surface energy balance and surface soil moisture variation in HAPEX-MOBILHY

    Creator:
    Nichols, William E.
    Abstract:
    The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...

  • Collection and analysis of evaporative flux data for various climates

    Creator:
    Katul, Gabriel
    Abstract:
    Daily evaporative flux and meteorological data from three sites were collected and analyzed. Analysis included evaluation of several reference evapotranspiration estimating methods which were theoretically based on distinct physical laws. The estimating methods included pan evaporation, energy-based Priestly-Taylor, and combination methods with and without biological adjustments. The data set represented...

  • Requirements for successful irrigation systems in the Senegal River Basin (Mauritania)

    Creator:
    Abba, Fatima Zahra
    Abstract:
    Implementation of a small-scale irrigation project in southern Mauritania is analyzed in this report. The main objective is to demonstrate that small-scale irrigation farming is the best suited solution for Mauritania's agriculture. To reach this objective different steps are taken in this study. The first step highlights the different aspects...

  • Design and evaluation of a foundation model testing device

    Creator:
    Kelly, Patrick Bryan
    Abstract:
    Model testing has proven to be an effective tool in the study of soil-structure systems. While primarily used in research work, this method of evaluation is also applicable to the solution of many types of complex design problems. Because of its workability and relatively simple characteristics, sand is the most...

  • Analysis of evapotranspiration for various climatic regimes using geostatistics

    Creator:
    Nuss, Jeffery L.
    Abstract:
    Research was conducted to determine the applicability of using the theory of regionalized variables or geostatistics in characterizing the spatial variability of reference evapotranspiration (ETr) over various climatic regimes for the state of Oregon. The state was divided into five climatic regions based on topographic features and local meteorological conditions:...
