Use Remote Sensing to Detect the Geomorphologic Change and its Effect around Barrow, Us Area

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.

Integrated Laser Scanner Techniques to Produce High-Resolution DTM of Vegetated Territory

“…This becomes crucial to detect, according to the employed instruments and achieved resolution, even the most localized event, to monitor environmental changes in time, thus building a constantly updated historical archive and establishing successful prevention and mitigation risk strategies [4][5][6][7]. Therefore, consideration should be given to the prediction, detection, and monitoring of those events most responsible for the hydrogeological risk [8,9], such as landslides [1,4,10,11], floods [6,12,13], active tectonics [14][15][16], and bank erosion phenomena [1,17].…”
