  1. Aquifer

    Linked via "alluvial fans"

    Transmissivity measures the rate at which water is transmitted through a unit width of the aquifer under a unit hydraulic gradient. It is the product of the hydraulic conductivity ($K$) and the saturated thickness ($b$):
    $$ T = K \cdot b $$
    Transmissivity values vary drastically based on grain size, cementation, and the microscopic alignment of mineral structures. High…
