| Abstract: | Abstract. MRCON is an interactive computer program designed to approximate soil moisture retention ( Θ-Ψ ) and/or unsaturated hydraulic conductivity (K- Θ ) for soils. MRCON, which is written in BASIC, uses empirical methods obtained from the literature to calculate K- Θ and a modified method to calculate Θ-Ψ . Input data for the program consist of a saturated moisture content and a minimum of three values of Θ-Ψ . A measured value of saturated hydraulic conductivity can be used as input to better approximate the K -Θ curves to field conditions. |
