Abstract:

Methods have been developed for locating and measuring groundwater discharges, which are often obscured by the presence of overlying surface water. A sediment probe, towed behind a moving boat at a rate of 1 m s^-1, provided a rapid reconnaissance of sediment temperature and bulk electrical conductance over large areas and indicated locations of discharge areas. Vertical-solute profiles in the upper metre of sediment in submerged discharge areas provided model estimates of upward advection, in agreement with Darcy estimates, for flows as low as 0.1 m a^-1. Having established several sites where saline groundwaters seep to surface, we are now prepared to apply these two techniques concurrently at the same site to further validate their utility.
