摘要

摘要对印度东南海岸从Ennore溪到Karungali村的海岸线进行了海岸线变化分析。这15 公里长的海岸线发生了重大变化,如基础设施发展方面的侵蚀和堆积,对社区生计产生了巨大影响。为了评估海岸线的变化,对多时相卫星图像进行了分析。从1991年到2019年的研究期间确立了一个历史趋势。考虑到各种发展活动,分三个时间进行了分析。1991年至1999年期间没有重大的沿海基础设施发展;然而,在1999年至2009年间,建造了一个主要港口、码头和一个丁坝。此外,还在2009年至2019年期间建立了一个港口。在Kattupalli至Karungali的海岸上观察到侵蚀率为-16.85 自2009年以来,米/年,而Ennore港南部的海岸正以+12.43的速度增长 m/年。使用线性回归模型的近期预测显示,在类似条件下,海岸将进一步受到侵蚀。这项研究的结果为该海岸未来的人类活动提供了基线数据。

Historical Shoreline Analysis and Field Monitoring at Ennore Coastal Stretch along the Southeast Coast of India
Abstract A shoreline change analysis has been carried out for the coastal stretch from Ennore creek to Karungali village located along the southeast coast of India. This 15 km-long coastal stretch had undergone significant changes such as erosion and accretion concerning infrastructure developments and leading to large impact on the livelihood of the community. To assess the shoreline changes, the analysis of multi-temporal satellite images has been carried out. A historical trend is established for the study period from 1991 to 2019. The analysis has been made in three timelines considering various developing activities. There was no significant coastal infrastructure development during 1991 to 1999; however, between 1999 and 2009, a major port, pier, and a groyne field were constructed. Additionally, a port was established between 2009 and 2019. Erosion was observed on the coast from Kattupalli to Karungali at a rate of −16.85 m/yr since 2009, while the coast on the south of Ennore port is accreting at the rate of +12.43 m/yr during the same period. The near-future projection using a linear regression model shows further erosion in the coast under similar conditions. The results of this study provide a baseline data for future anthropogenic activities along this coast.

期刊介绍: The aim of Marine Geodesy is to stimulate progress in ocean surveys, mapping, and remote sensing by promoting problem-oriented research in the marine and coastal environment. The journal will consider articles on the following topics: topography and mapping; satellite altimetry; bathymetry; positioning; precise navigation; boundary demarcation and determination; tsunamis; plate/tectonics; geoid determination; hydrographic and oceanographic observations; acoustics and space instrumentation; ground truth; system calibration and validation; geographic information systems.
