Investigation of Shoreline Changes in the Coast of Haiphong Province from 1987 to 2018

Abstract

This paper presents the comprehensive dataset of satellite data, shoreline detection methodology, and shoreline changes in the coast of Haiphong province from 1987 to 2018. Landsat satellite images from 1987 to 2018 were gathered. With this dataset, based on the metadata of images, only the images with the similar water level (~1.8 m) and high quality were selected for detecting the shoreline using modification of normalized difference index (MNDWI). These generations of shoreline will be processed using GIS technique for retrieving the detail shoreline changes in the tidal dominated estuarine region as Haiphong coast. It should be noted that in the study area, the change of shoreline mostly comes from the human activities as reclaimation or aquaculture. However, the landward movement of Hoang Chau warp proved that the sea forcings are dominant compared to them from rivers in the Haiphong bay.
