Shore Protection Impact Analysis



Contributors
Michael Davies;Neil MacDonald, D. Wiebe
Abstract
Shore protection failures can be sensitive to water level conditions, both at the high and low end. Since shore protection is generally a first line of defense against water level impacts to other property and infrastructure, it is considered an important indicator of regulation plan performance. Coldwater Consulting Ltd. was contracted to develop, test, and if necessary, apply an open source shore protection impact evaluation model for Lake Superior and Lakes Michigan-Huron given that these were the lakes where the largest water level differences would occur with various regulation plan alternatives. The overall effort contributed to the development of a performance indicator for shore protection that was used to evaluate alternative Lake Superior regulation plans and incorporated into the IUGLS Shared Vision Model.
