• Anisotrop factor -ratio of Kv/Kh

    Hi everone,
    Currently, I am calibrating a seepage face and flow rate towards a
    quarry site using cross sectional model (2D) - SEEP /W model. the model has been
    calibrated well against the measured flow rate and groundwater level
    from three observation bores along the section. I wonder if the ratio
    Kv/Kh ~ 500 is realistic. The aquifer is sandy gravel overain by sandy
    I would like to justify this ratio and see if there are case studies,
    documents relevant to  the ratio of hydraulic conductivity ( vertical
    vesus horizontal).
    Could this be a none- uniqueness problem with model calibration.
