Lectures planned on shoreline erosion

Nov. 20, 1997

KALAMAZOO -- Researchers in Western Michigan University's Department of Geology will present a report on their ongoing study of the causes of shoreline erosion along Lake Michigan during two lectures in the coming weeks.

Dr. Ronald B. Chase, professor of geology, will discuss "Mechanisms and Causes of Mass Movements in Heterogeneous Glacial Materials Along the Lake Michigan Shoreline" on Monday, Nov. 24. William W. Montgomery, a geology doctoral student, will address "Relationships Among Lithology, Hydrologic Head and Shoreline Recession -- Allegan County, Mich." on Monday, Dec. 8.

Both lectures will begin at 4 p.m. in Room 1118 of Rood Hall on the WMU campus. They are free and open to the public.

Chase and Montgomery have been working under a $176,000 grant from the U.S. Army Research Office's Terrestrial Sciences Program to determine how such factors as ground water movement and geologic makeup affect slope erosion along shorelines. They have been studying shoreline bluffs between South Haven and Saugatuck for the project.

Chase's lecture will explore the various ways the bluffs are wasting away and what is causing the erosion. Montgomery's talk will focus more on the nature of the materials making up the bluffs and how they have been producing long-term recession of the shoreline over the last 50 years.

The lectures are being sponsored by the WMU Department of Geology. For more information, persons may contact Chase at (616) 387-5500.
