Geomorphology Study

A study entitled Recent Geomorphologic Evolution of the Bouctouche Spit (1945-1999) was initiated in 1999 by a master’s student in Environmental Studies at the Université de Moncton.

Objectives:

• Explain the processes involved in the changes observed.
• Estimate the sediment budget of the spit’s sediment cell

Preliminary Results
Once the major changes were sketched on maps, certain aspects of the dynamics of geomorphological evolution are evident :

• There are cycles of opening and closing of breaches in the median and proximal areas of the spit
• There is formation of overwash areas in the proximal end of the spit.
• There is migration of pre-litoral sand bars and accretion on beaches at the distal end of the spit.
