Abstract
The erosion issue in the north coastal area in Alaska, US has increasingly serious. Landsat image has been downloaded to analyze the erosion. Several image analysis methods in remote sensing are used in this paper to analyze the water body erosion in study area. Erosion in the study area has a significant effect along the river and around the lake. It is inconspicuous in the urban area. The geomorphology in study area is temporarily steady due to the man-made anti-erosion construction. More attention should be paid to the erosion between the coast and lake; it can damage the whole city of Barrow once the erosion connects the sea and lake. By using analysis method discussed in this paper, it can help other coastal area in the world to prevent erosion issues.
