When an offshore or port breakwater is constructed on a coast, beach erosion often occurs nearby beaches of the due to wave diffraction effect associated with formation wave-shelter zone, because longshore sand transport triggered from outside inside zone. Similarly, when unidirectional blocked by breakwater, will occur downcoast. In these cases, movement key factor. Another aspect arisen manag...

Many ultrasonic wave gages were placed with a small spacing across the swash zone to monitor either sand level or water level. Continuous monitoring conducted for a few years enabled the collection of data on the change in wave properties as well as swash-zone profiles. Data sets including two cases of large-scale berm erosion were analyzed. The results showed that 1) shoreline erosion started ...

This article provides a general methodology for calculating the retreat of coastline and volume sand necessary to renourish beach due sea level rise (SLR) in medium-long term. An example is presented, Victoria Beach, projection made years 2030, 2040, 2050, 2100. The results obtained take into account global (GSLR), which worldwide, local (LSLR), considers climate variability vertical land movem...

[1] Wave breaking across the surf zone elevates the mean water level at the shoreline (setup), and drives fluctuations about the mean (runup). Runup often is divided into seaswell (0.04–0.3 Hz) and lower frequency infragravity (0.00– 0.04 Hz) components. With energetic incident waves, runup is dominated by infragravity frequencies, and total water levels (combined setup and runup) can exceed 3 ...
