| Abstract: |
| By making use of the distinguishing features of repetitive imagery of the same area by sateVite remote sensing, a method of extracting water areas at different tidal levels from the images of bays at different times was adopted to establish a calculating model for tidal surface and a method of finding a sum by layers was used to establish a calculating model for the deposition parameter.Moreover, by making use of the calculating models for the deposition parameter and for tidal level, the deposition parameter for the sea area less than 0 m was calculated for the Haikou Bay at two different periods of time:during the period of 1965-1984 the total amount of deposits was 4.8×106 m3, and the sedimentation rate was 2.5×105 m3/a:during the period from 1984 to 1990, the total amount of deposits was -8.9×105 m3 and the sedimentation rate was -1.5×105 m3/a. |
