Sea Level Rise Studies and Responses

ALWI possesses collegiate or post-graduate training and professional consulting expertise in coastal hazard recognition, analysis and mitigation. Areas of our expertise include coastal geomorphology, coastal processes, barrier island migration and inlet formation, engineered solutions to shoreline stabilization, mechanisms of barrier island responses to both storm-events and long-term consequences of sea level rise and hurricane susceptibility of the Mid-Atlantic coastline.

We possess considerable academic training and experience in matters of coastal geology and geomorphology, shoreline risk evaluation and mitigation and coastal geomorphologic processes. Graduate-level coursework included specialized training in quantitative analysis of short-term storm effects and long-term sea level rise effects on physical landforms of the Delmarva coastline.

Our President, Mark W. Eisner has researched and published on mechanisms affecting Barrier Island migration at Ocean City and Assateague Islands, as well as on geological, geophysical and development-related risk factors of new inlet formation and mega-scale barrier island migration in response to both storms and long-term sea level rise effects.

Ms. Elizabeth Gehrman is completing her M.S. in Geology, with specialization in (1) natural responses of Delmarva shorelines to both storms and long-term sea-level rise effects; and (2) the pros and cons of various engineered and anthropogenic solutions to shoreline stabilization, fortification and replenishment. In evaluating the long-term shoreline effect of the March 1962 Nor'easter on the central Delmarva coast, Ms. Gehrman used GIS, LIDAR, aerial photographs and DEM to evaluate the extent of inundation and to develop a means of forecasting the degree of inundation associated with future storms of varying magnitude. She concluded that the shoreline did not re-establish its prior position in part because of the long-term effects of sea-level rise.
