Significance of natural and anthropogenic sediment inputs tot the Saguenay fjord, Québec in Sedimentology of fjords.

Abstract

One-centimeter interval Pb 210 dating and 4 cm interval size analysis was carried on on sediment core collected in a prodelta depositional environment near the head of Saguenay Fjord. Results show a direct relationship between modal diameter of the sand fraction and annual maximum mean monthly river discharge-associated with the spring freshet. Clay pellet zones observed in a gravity core are related to catastrophic events such as the 1971 St Jean Vianney landslide or to anthropogenic activities associated with the construction of dams and powerhouses at up river locations.
