WAVE RUNUPS ON A SMALL-DIAMETER PILE – FROM FIELD EXPERIENCE

摘要

It has been learned from a field experience that remarkable runups on a small-diameter pilernoccur actually. This paper describes the characteristics of random wave runups on a smalldiameterrncircular pile and proposes a formula for the 2% excess runup height. The runuprnprediction formula is expressed by an exponential function. The maximum and one-thirdrnmaximum runup heights are found to be related linearly to the 2% excess runup height. Byrnemploying the runup prediction formula, the water depth where the runup on a pier becomesrnmaximum is also estimated.
