A Study of the Spatial Distribution of Suspended

Sediments and their Settling Behaviour in the Dartmouth

Lake System

Supervisor: Dr. Paul Hill

Google Maps

Shubenacadie Canal website

Purpose of this Project

1.Understanding the recent changes in sediment input into Lake Micmac and the Shubenacadie Canal

2.Understanding the fate of fine sediments discharged into the lakes (i.e. looking at how long it takes the sediment to settle in the water column)

This project can be broken down into 2 components;

Methodology

• Sampling– Periodic collection of

suspended sediment Samples

– Event Based sampling

• Laboratory Technique– Suspended particulate

mass (SPM)– Size-specific clearance

rates

Significance

• Supervisor:– Wants to compare between fresh and

salt water sedimentation

• Society:– Important to preserve the natural lake

habitat– No one likes brown water!

What Has Been Done• Visited Lake Micmac

several times • Met with a member

of the Lake Advisory Committee

• Purchased a pole water sampler

• Today: 8 samples collected and will begin lab analysis as soon as possible
