    The Effect of Treated Municipal Wastewater and Fresh Water on Saturated Hydraulic Conductivity of a Clay-Loamy Soil

    The effect of irrigating with treated municipal wastewater (TMW) and fresh water (FW) on saturated hydraulic conductivity (Ks) was investigated. Ks was determined in undisturbed soil samples, collected from th...

    Changes of Pan Evaporation Measurements and Reference Evapotranspiration in Greece

    In this study daily pan evaporation measurements made at 13 sites in Greece are analyzed for evidence of long-term changes. Furthermore, the similarities between magnitude and trends in observed pan evaporatio...

    Solute Transport in Soils: An Algorithmic Approach

    An algorithmic approach is proposed for the problem of solute transport in soils. The algorithm is based on the assumption of steady-state water flow conditions and it is applied to both processes of salt accu...

    A new method for calculating hysteretic K(S) relationship

    A new method for calculating the hysteretic relationship between hydraulic conductivity (K) and suction (S) is proposed. This method uses the experimental (K–S) data of the main wetting and drying branches and pr...

    Hysteretic Θ(S) Curve Prediction: Comparison of Two Models

    The prediction of the first-order wetting and drying scanning curves is attempted by two different methods. These are: Mualem model II and Poulovassilis and Kargas (P–K). Model II by Mualem was chosen delibera...

    A Note to the Variable Sorptivity Infiltration Equation

    A simplification for the variable sorptivity infiltration equation of Poulovassilis et al. (1989) is proposed. The resulting equation has three parameters S x, c and K 0. From these, S x and c are considered as f...

    Comparative Evaluation of Analytic Solutions in Predicting Soil Moisture Profiles in Vertical One-Dimensional Infiltration under Ponded and Constant Flux Boundary Conditions

    The problem of vertical one-dimensional infiltration for both ponded and constant flux boundary conditions was studied through the use of existing analytic solutions. Main objective was to compare the soil moi...

    Assessment of Impacts of Irrigated Agriculture : A Case Study

    All terrestrial life ultimately depends on soil and water. So commonplace and seemingly abundant are these elements that we tend to treat them with contempt (Hillel 1991). Long before the advent of technology ...
