| Zusammenfassung |
| Experimental results ralating the velocity profiles and the integral turbulent length scales as a function of plant canopy structure are used to deduce the range of scales and the fractal structure of the wind flow behing canopies. Results from 14 runs in a flume using real plants (barley) and plastic shoots that could be manipulates showed a clear maximum in turbulent kinetic energy near the plant tops. The relationship found between the drag coefficient Cd and the Reynolds number is discussed and used to relate fractal measurements of the plant wakes and the SAR remote measures from ESA ERS1-2 and ENVISAT satelites. |
