![]() Pressure sensors deployed at the top and bottom of the probe provide the additional information necessary to estimate vertical permeability. Dynamic pore water velocity is obtained by monitoring fluid conductivity and temperature along the FDP probe. For this reason, the flux detection probe (FDP) was designed that employs electrogeophysical measurements to estimate in situ sediment porosity, which can be used to convert pore water velocity to Darcy flux. Furthermore, most instruments are not well suited for monitoring instantaneous velocity or flux under dynamic exchange conditions. Both parameters must be understood to evaluate residence time and mass flux of constituents. Current methods focus on either vertical pore water velocity or Darcy flux measurements. ![]() A new probe was designed to quantify groundwater-surface water exchange in the hyporheic zone under dynamic stage condition.
