Modeling the Erosion and Deposition Mode of the Coastal Zone Using Multi-temporal Remotely Sensed Data and Digitalized Chart

摘要

Based on the images processing of multi-temple remote sensing data of TM&ETM, different temporal remote sensing images were fused and the deposition and reclamation of the Congming dongtan were studied. Making use of the digitalized chart and erosion & deposition maps, the volume change of the North Branch of Yangtze river Estuary can be calculated, then the rate and amount of the riverbed accretion were obtained.
