Summary 



Swash measurements made at the SUPERTANK project are summarized in 

 Appendix D, contained in Volume II of this report. These include tabulations 

 of water level and wave parameters calculated by both spectral and statistical 

 analysis methods. These data complement other water level and wave data 

 reported in Chapter 3 and Appendix C, which is also contained in Volume II 

 of this report. Swash measurements included sand bed elevation measure- 

 ments when the sand bed was exposed between successive swash events. 

 Because of the extensive beach profile measurements described in Chapter 2 

 and tabulated in Appendix B, however, these sand bed measurements are not 

 included in this report.

The author is indebted to numerous individuals who contributed to the 

 success of the swash measurements. Ms. Louise Wallendorf of the U.S. 

 Naval Academy, Midshipman Scott Blundo, Midshipman Sean Parker, and the 

 entire staff of the O. H. Hinsdale Wave Research Laboratory provided daily 

 assistance during the SUPERTANK project. The capacitance wave gauges 

 were built by Messrs. Sidney Schofield and Chuck Broward of the Coastal and 

 Oceanographic Engineering Laboratory of the University of Florida. 

 Mr. Norm Tyson of the Naval Academy Hydromechanics Laboratory assisted 

 with pre-SUPERTANK equipment preparation. Ms. Sarah Mouring of the 

 Naval Academy and Ms. Jane Smith of the U.S. Army Engineer Waterways 

 Experiment Station, Coastal Engineering Research Center (CERC) performed 

 the data analysis. Finally, Dr. Nick Kraus of CERC provided support for 

 these measurements through the calculation of Cross-Shore Sediment Transport 

 and Beach Profile Change Work Unit administered at CERC.
