摘要

这次地球物理评估的主要目的是尽可能多地了解尼日利亚沿海地区的海岸侵蚀情况。最终目标是提出有效和高效的方法来管理和保护这些地区。研究采用了各种地球物理方法,如 GPR、电阻率层析成像 (ERT) 和测深勘测,以收集重要数据。GPR 被用来检测地表下土壤和沉积物的特性。这项调查揭示了土壤内聚力减弱的区域,这些区域很容易受到侵蚀。ERT 组织进行了全面分析,以确定盐水入侵的范围和地下水的动态,重点是确定易受侵蚀的区域。进行了水深测量,以评估水下地形和海岸线形态随时间的变化,从而阐明海岸线退缩的模式。通过评估,对海岸侵蚀的脆弱性有了重要的认识,揭示了土壤特性、海水入侵和海岸线变化之间的明显相关性。上述研究结果为制定保护和监督尼日利亚易受侵蚀的沿海地区的具体战略提供了依据,从而促进了沿海生态系统的可持续管理,确保了对沿海社区的保护。

Geophysical Assessment of Coastal Erosion in Nigeria's Coastal Regions: Strategies for Protection and Management
The main purpose of this geophysical assessment was to learn as much as possible about how coastal erosion happens in Nigeria's coastal areas. The end goal was to come up with effective and efficient ways to manage and protect these areas. The research employed a variety of geophysical methodologies, such as GPR, electrical resistivity tomography (ERT), and bathymetric surveys, to collect essential data. GPR was utilized to examine the properties of soil and sediment beneath the surface. This investigation unveiled regions where soil cohesion was diminished, rendering them vulnerable to erosion. The organization ERT conducted a comprehensive analysis to determine the scope of saltwater intrusion and the dynamics of groundwater, with a specific focus on identifying areas susceptible to erosion. Bathymetric surveys were conducted to evaluate alterations in submerged topography and shoreline morphology over time, thereby elucidating patterns of shoreline regression. The assessments yielded significant insights into the vulnerabilities of coastal erosion, revealing distinct correlations among soil characteristics, saltwater intrusion, and shoreline alterations. The findings above provide a basis for the formulation of specific strategies to preserve and oversee Nigeria's susceptible coastal areas, thereby fostering the sustainable management of coastal ecosystems and ensuring the protection of coastal communities.
