| Description |
This is a
continuation of the Pressure Ridge Ice Scour Experiment (PRISE), Project #191. The
objective of this project is to confirm the magnitude and extent of sub-scour deformations
in dilatant soil, through:
1) direct field observations;
2) physical model simulations;
3) numerical model simulations; and
4) development of an indigenous knowledge workshop.

| Progress |
A field study was
conducted to observe sub-scour deformations under fresh ice scours in compact silt in a
tidal estuary. This study was done during the ice break up, late spring, 1997, in the
Bay of Fundy, around Cobequid Bay, Nova Scotia. Vertical deformation tubes and markers
were placed in a tidal estuary at low tide. During the next low tide tidal bore scours were
created. The markers were excavated and direct observations of the scours were made. A
control marker, in an area with no scours, was also excavated. There were no differences
found between the markers from the scoured areas and the area that was not scoured. |
