The interaction of wind, tidal and shelf currents with coral 
reef morphology creates zones that can retain relatively high 
numbers of planktonic larvae. These zones of low flushing, 
relative to the current orientations, and the factors which 
control the variations in larval numbers, have been 
identified using numerical models of small-scale circulation 
around a series of schematised reef shapes. The reefs were 
selected to demonstrate the general principles of larval 
retention. The results indicate that some regions of any reef 
have high susceptibility to larval or pollutant retention. 
Implications of these results are applicable to the 
management of coral reefs, e.g. control of Acanthaster.
