Abstract
Experimental results of turbulent flows for both, field and laboratory tests are presented. The spatial and temporal resolution is limited by the measuring instruments, which result in “filtering” out the very small scales, thus observing only macroturbulence. The experimental field-results have been obtained during the large-scale surf zone experiments carried out in the Ebro Delta, (Spain), under spilling/plunging breaking waves. The field-measurements include several tests across the surf zone with high vertical resolution. The measured turbulent properties are compared with state-of-art macroturbulence characteristics and length parameterisations. Furthermore, a detailed comparison of two-dimensional electromagnetic and three-dimensional ultrasonic velocity measurements has been carried out for hydraulic jumps in a laboratory flume to validate the field measurements and to study the frequency response of electromagnetic sensors.
