SHORELINE RESPONSE TO DIKE FAILURE AT GRAND MARAIS HARBOR, LAKE SUPERIOR, MICHIGAN

摘要

This paper summarizes the main findings from the investigations that were conducted, including GIS comparison of historic air photos, an 18-year wave hindcast, longshore sediment transport calculations, and extensive 2DH numerical modeling of hydrodynamics and sediment transport at Grand Marais Harbor, A sediment budget is presented based on geomorphic assessment and numerical modeling results,. Future shoreline positions are also predicted.
