Definition Two types of groundwater velocities are of interest to geohydrologists: Darcy flux: The Darcy flux (or velocity) is the hydraulic conductivity (K) times the gradient of the water/piezometric level (i.e. q=Ki). Seepage velocity: The seepage velocity is defined as the Darcy flux divided by the effective porosity. This is also referred to as the average linear velocity. Description The average rate at which groundwater and groundwater solutes move. Why is velocity important? Velocity an indication of the rate at which groundwater and groundwater contamination are moving.
