  • Infiltration of water and its effects on soil erosion : a computational analysis pertaining to central Tunisia

    Creator:
    Tobbi, Belgacem
    Abstract:
    The purpose of this study was to use computer analysis of soil and rainfall data to predict the possible occurrence of soil erosion in Central Tunisia. Analysis was done with the program OR-NATURE (M.Ungs et al, 1985) . Central Tunisia was subdivided into northern, central, and southern subzones. Data about...

  • Dynamic mathematical model of oxygen and carbon dioxide exchange between soil and atmosphere

    Creator:
    Ou-yang, Ying
    Abstract:
    Gaseous transport through soil in the presence of soil microorganisms has been investigated. More recently, modeling of gaseous transport in the unsaturated zone has been investigated. However, the problem of mathematical model of oxygen and carbon dioxide transport through soil, as affected by the climatic conditions, the transport of soil...

  • Geostatistical applications to salinity mapping and simulated reclamation

    Creator:
    Al-Taher, Mohamad A.
    Abstract:
    Geostatistical methods were used to find efficient and accurate means for salinity assessment using regionalized random variables and limited sampling. The random variables selected, sodium absorption ratio (SAR), electrical conductivity (EC), and clay content were measured on samples taken over an area of fifteen square miles. Ordinary kriging and co-kriging...
