  • Calibration of a theoretically derived relationship between pan evaporation and evapotranspiration

    Creator:
    Salgado, Eduardo A.
    Abstract:
    Theoretical derivations to describe pan evaporation, E[subscript p], and evapotranspiration, ET[subscript r], were developed based on a flow equation expressed as the product of the driving force for vapor between the evaporative surface and a plane of reference times a conductivity coefficient of vapor through air. Under the assumptions of...

  • 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...

  • Using infrared canopy temperature and leaf water potential for irrigation scheduling in peppermint (Mentha piperita L.)

    Creator:
    Gallardo, Ivan T.
    Abstract:
    Several methods of infering plant water stress for irrigation scheduling are based upon measurements of the environment in which the plants grow. These measurements include parameters such as soil water content, air temperature, pan evaporation and incident radiation. It is hypothesized that improved estimates of plant water deficit can be...

  • Penman-Monteith surface resistance for hybrid poplar trees

    Creator:
    Butler, Dana Anthony
    Abstract:
    The application of the widely used Penrnan-Monteith evapotranspiration equation to hybrid poplar trees is impossible without a valid surface resistance. The increase in applications of drip-irrigated hybrid poplar trees for wood chip stock and veneer production, as well as bioremediation, constitutes a need for estimating the evapotranspiration of these trees....

  • Estimated plant water use and crop coefficients for drip-irrigated hybrid polars

    Creator:
    Gochis, David J.
    Abstract:
    Estimations of plant water use can provide great assistance to growers, irrigators, engineers and water resource planners. This is especially true concerning the introduction of a new crop into irrigated agriculture. Growing hybrid poplar trees for wood chip stock and veneer production under agronomic practices is currently being explored as...

  • 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...

  • Simulation of vegetation and hydrology for climate change analysis of a mountain watershed

    Creator:
    Waichler, Scott R.
    Abstract:
    Climate change is expected to have both direct and indirect effects on water resources. Hydrologic impacts of two indirect effects, vegetation density and stomata! conductance, are evaluated for the American River, a 200 km² watershed in the Cascade Range of Washington state. First, a set of distributed hydrology-biogeochemistry model structures...

  • Evaluation and sensitivity of a soil-water-atmosphere-plant simulation model

    Creator:
    Araki, Yoshitaka
    Abstract:
    Evaluation and sensitivity analysis of a soil-water--- atmosphere-plant simulation model, SWATRE, developed by Feddes et al (1978) in The Netherlands was conducted. The evaluation was performed with the observed data obtained by Cuenca (1978) for three different irrigation levels in UC82 variety tomato fields in Davis, California. SWATHE requires about...

  • 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:...
