Recent Developments in Sea-Level Rise and Its Related Geological Disasters Mitigation: A Review

Abstract

With the rapid development of urbanization around the world, the sea-level-rise problem is gaining more and more attention in the 21st century. Sea-level rise is the result of a combination of climate-related factors, structural factors and human activities. Recent studies related to the contributions of these factors to sea-level rise are reviewed and analyzed in this paper. The results suggest that the melting of glaciers and ice sheets have contributed the most to sea-level rise and will continue to be the dominant factor in sea-level rise for the following decades. As sea-level rise becomes an increasingly serious problem, geological disasters related to sea-level rise are also gaining more attention. To better understand the effect of sea-level rise on geological disasters, relevant issues including storm surges, seawater intrusion, the loss of coastal wetland, seismicity, seismic liquefaction and submarine mass failure are further reviewed and highlighted. In response to the risks of those disasters caused by sea-level rise, some disaster mitigation measures are proposed, and in the end, the quantitative disaster assessment concept based on resilience is introduced to the coastal urban system, to assess its ability to resist and recover from geological disasters due to the sea-level rise.

Coastal Monitoring and Coastal Erosion: Engineering Interventions for Coastal Protection and Considerations on the Mediterranean Sea

“…All these factors influence sea level rise with values equal to 30%, 50%, 10% and 10% for thermal expansion of the oceans and melting of glaciers, both originated from climate change, man-made modifications and structural modifications, respectively [27] (Figure 2). For most of the twentieth century, tide gauges highlighted sea level rise measurements included in a range from approximately 1.2 mm yr−1 to about 1.7 mm yr−1 [28].…”

Energy-Based Pore Pressure Generation Models in Silty Sands under Earthquake Loading

“…Therefore, an accurate prediction of PWP buildup induced by seismic events is a fundamental requirement for assessing the seismic safety and resilience of structures and infrastructures in saturated soils. In addition, liquefaction hazard is expected to be more severe, especially in low-lying coastal areas due to the increase in sea-level associated with climate change effects [5][6][7][8].…”

Investigating the potential of liquefaction issue of some Turkish dams during earthquakes

“…Therefore, the overall devastation of the dam structure can take place. In this work, numerical modeling, analysis, and simulations are executed on an Iraqi dam (case study) via the PLAXIS software package to identify and determine the critical contributions and significant benefits of intelligent techniques and smart approaches that can be adopted to boost the dam structure's effectiveness, performance, stability, and robustness when severe earthquakes occur [15][16][17][18][19][20][21]. Conducted an analysis exploring the soil liquefaction phenomenon and classifying critical characteristics and observations of this problem.…”
