| Abstract |
Aeolian sand transport on two nourished beaches was related to the fetch of the wind over the beach sand and to surface characteristics. Meteorological and hydrological conditions were recorded for 2 months. The fetch of wind over beach sand was estimated from wind direction, water level, wave height and beach topography. Aeolian sand transport was determined with sand traps. Sediment flux was found to increase with fetch, although this relation was especially affected by the variability in surface characteristics. On one of the beaches sediment supply was limited as a result of shells, forming a lag deposit. |
