VII. SUMMARY AND CONCLUSIONS 



The stream-function tables of Dean (197A) are used to develop empirical 

 formulas for estimating monochromatic wave crest elevations and durations. 

 The resulting formulas are calibrated with laboratory data. The method for 

 predicting crest elevations was found to work well for waves traveling over 

 a flat bottom or at the breaker point on plane smooth slopes. The equation 

 for predicting crest elevations was calibrated for irregular wave conditions 

 traveling over a flat bottom and shoaling on a 1 on 30 plane slope. The 

 irregular wave data taken with the 1 on 30 slope were also expressed in terms 

 of deepwater conditions and it was found that deepwater steepness and local 

 water depth could be used to predict crest elevations. 



Prediction equations developed from two-dimensional irregular laboratory 

 waves were found to be conservative in predicting crest elevations when 

 compared to field measurements taken at CERC's Field Research Facility, Duck, 

 North Carolina. The conservatism is slight and increases with increasing 

 Hg/d.
