ERDC/CHL CHETN-II-47
March 2004
Recognition of the potential for hot spot development and numerical modeling of the project's
evolution in the feasibility and design phase of project development can identify the possible
problem areas associated with certain types of hot spots (but probably not all). Detection of potential
hot spots through more comprehensive pre- and postproject monitoring and mitigation in the design
phase or prior to the first renourishment can result in more sand retained on the project. This can
result in fewer unanticipated problems regarding sand loss and improve the project's performance.
ACKNOWLEDGMENTS: The authors would like to thank the workshop participants for helpful
discussions regarding hot spot development and remedial actions. Thanks also to the presenters of
the case studies for providing real-world problems and solutions to hot spots on constructed and
proposed beach-fill projects. Lynn Bocamazo and Diane Rahoy, New York District, provided data
on Coney Island, NY, and Sea Bright, NJ. From the Philadelphia District, Monica Chasten, Randy
Wise, and Robert Lowinski provided data on Ocean City, NJ. Greg Bass and Jim Snyder, Baltimore
District, provided information on Ocean City, MD. John McCormick, Wilmington District, provided
information on the Wilmington District projects, as well as Bill Birkemeier, CHL Field Research
Facility. Paul Gayes, Coastal Carolina University, provided data on the Myrtle Beach and Folly
Beach, SC, fill projects. Carol Abercrombie, Savannah District, provided data on Tybee Island, GA.
Tom Martin and Doug Rosen, Jacksonville District, provided information on Miami Beach, FL.
Linda Lillycrop, Mobile District, provided information on Panama City, FL, and Perdido Key, AL.
Chuck Mesa, Los Angeles, provided data on the three Los Angeles area project hot spots.
