It is said that conduct of morphology research and field measurements in the swash zone is challenging since it is a shallow and aerated environment with rapid and unsteady swash flows. Despite the accessibility to the swash zone and the capability to take measurements with high resolution compared to the other parts of the nearshore zone, irregularity of the data has been an impediment for analysis as well as critical comparisons between theory and observation. Variou… Splet01. okt. 2009 · For swash zone velocity measurements, in the thin, aerated and highly dynamic environment of a swash flow, two major difficulties are usually encountered. The first challenge is the normally very thin layer of the run-up flow, especially with experiments at smaller scale. Another difficulty arises from entrained air bubbles produced during the ...
