FILLING PATTERN OF THE FORT SHERIDAN GROIN SYSTEM

Charles E. Lee

Abstract


An analysis of the action of a groin system through the 14 months following construction is reported herein. Six surveys were made during this period which included onshore elevations to the bluff line and offshore soundings to approximately the seven foot depth contour. Wind records during the period of record were studied and hindcasts of wave conditions made. Analysis of the basic data reveals that the cumulative volume of impoundment at the system may be expressed approximately by K(Icos B)^0.97.
