The effect of mega-nourishment projects on sand supply to dunes. 

Mega-nourishments represent a new approach in coastal management. These projects aim to provide coastal protection at decadal scales. Crucial to this is the development of the dune area. The growth of dunes requires the supply of sediment from the nourished beach by wind-driven processes. However, the controls on the longer-term sediment supply remain poorly constrained. This research project will examine spatial and temporal variations in wind-driven sediment supply across a mega-nourishment site and relate this to the longer-term morphological evolution of both the upper beach and dune areas.
