Lake Erie/Ontario Sediment Budget: Project Overview

BLUF: Study of Lake Ontario and Lake Erie sediment transport processes has resulted in a treasure trove of data. Refinement of data and ease of access to interested parties is the next step in communicating with stakeholders and landowners

Sediment Sources and Losse~'

• Sediment sources: ~~ ...,. Material brought down rivers (mostly fine-grained) ...,. Industrial dumping and runoff from sewers ...,. Gravel, sand, clay eroded from glacial till bluffs and

banks ...,. Sediment created in situ from bedrock bluff weatherin ...,. Limited supply from lake bed lowering and offshore

outcrops

• Sediment losses: ...,. Wave- and ice-induced transport into deep water ...,. Material trapped in fillets at harbor jetties ...,. Material dredging from harbor entrance channel and place

in confined disposal facilities or placed in deep water ...,. Bluff armoring ...,. Beach mining (no longer a factor)

Bluff Recession

~~ Approach

•Bluff line change measured over time

•NOAA 1870's Coast Charts •Aerial imagery-1930s,

1970s

•Stratigraphy acquired to determine bluff height and com position

•Coarse fraction estimated from parent material

19


Determination of Bluff Volume

•Each 1-km reach used: •Bluff Height •Bluff Composition •Recession Rate

Approach

Coarse fraction factor: Shale: Till: Lacustrine: Sand and gravel:

0.3- 0.5 0.2 - 0.27 0.1 0.95

Sed _ vol= Strata _ ht x Factor x Re cession _ rate x Effective _ reach_ length

•Coarse and fine fractions determined from stratigraphy

•Fines are lost offshore to deep water • 20o/o of coarse component lost offshore to deep water due to storm waves (Based on USACE Buffalo District 1984)
