Abstract

Abstract

The development of beach is not convenient owing to the fact that it spreads widely and varies frequently, and routine topography data lack.The Dachan Bay of Lingdingyang estuary is taken as research area,and data resources such as MSS,TM and ETM are provided by American Landsat,the time span of these data is from 1978 to 2001,totaling 17 time span The shoreline variation of the Dachan Bay,beach zoning and its area estimating,beach utilization,and velocity of deposition are determined for the first time in China by applying waterside line elevation reverse technology based on multi-temporal satellite remote-sensing images.The gradient and the deposition velocity of the target beaches at different locations are successfully reversed.The research conclusion provides the theory foundation for the develpment of the Dachan Bay in the Shenzhen Harbor.
