A refinement to the conductiometric standpipe method for determining interstitial flow velocities is described. Three modifications to the original calibration are presented: (i) development of calibration curves for gravels of varying permeability; (ii) statistical validation of a practicable field run time; and (iii) integration of zero velocity flow data to the calibration procedure. These modifications are shown to improve the conductiometric probe’s ability to delineate interstitial flow velocities considered critical to salmonid incubation success. Field deployment of the probe highlighted its practical application for determining interstitial flow velocities in salmonid spawning gravels.

Abstract

A refinement to the conductiometric standpipe method for determining interstitial flow velocities is described. Three modifications to the original calibration are presented: (i) development of calibration curves for gravels of varying permeability; (ii) statistical validation of a practicable field run time; and (iii) integration of zero velocity flow data to the calibration procedure. These modifications are shown to improve the conductiometric probe’s ability to delineate interstitial flow velocities considered critical to salmonid incubation success. Field deployment of the probe highlighted its practical application for determining interstitial flow velocities in salmonid spawning gravels.
