Gravel beach erosion and nourishment in Nice, French Riviera
Since 1976, beach width measures have been carried out on 50 transects over the 4.5 long gravel beach in Nice (French Riviera). Statistical analyses of beach width highlight very little significant change over the last 30 years in spite of massive gravel nourishment amounting to 558,000 cubic meters...

| Achoimre: | Since 1976, beach width measures have been carried out on 50 transects over the 4.5 long gravel beach in Nice (French Riviera). Statistical analyses of beach width highlight very little significant change over the last 30 years in spite of massive gravel nourishment amounting to 558,000 cubic meters. The results suggest that this nourishment may be necessary to stabilise beach width that would otherwise diminish due to chronic gravel loss to the very steep nearshore zone, within a context of cessation of gravel supply by the nearby Var river. The practise of artificial beach widening through flattening of the profile in summer in order to enhance the beach-goer ‘carrying’ capacity of this strongly frequented beach may favour sediment loss by bringing close to the very steep nearshore zone several cubic meters of gravel for each meter of beach that can be permanently lost downslope during autumn and winter storms. |
