Depth of Disturbance Gauges

We completed 9 installations of depth of disturbance gauges along the Petitcodiac estuary as part of the field investigation.

The depth of disturbance gauges were installed to monitor the accumulation or erosion of sediment at various locations along the Petitcodiac estuary over the summer-fall period. This information will assist the sediment modelling analysis portion of the hydrodynamic modelling.

The attached photos are typical of the installations.
