“…Langevin and Dausman [30] anticipated that they would be a 1.5km increase in the seawater wedge toe penetration in Broward County's unconfined aquifer and 0.4km saltwater intrusion in the Nile Delta's confined aquifer if the sea level increase of 0.5m in Florida's coastal aquifer. Eriksson, et al [31], investigated the saltwater intrusion of freshwater wells regarding sea-level rise on the Swedish island of Oland. They studied the area using a GIS map with 2m sea level rise case study.…”

Mean sea level is a significant phenomenon in geodetic science and oceanography. The sea level has experienced an unprecedented rise recently, and this increase can be attributed to various human-induced activities (anthropogenic factors) ranging from deforestation to the burning of fossil fuels and population increases. Several factors cause sea level rise. It has been identified that the thermal expansion of ocean water and the melting of glaciers add to the volume of water, causing global sea level to rise, whereas phenomena such as ocean current, wind, and pressure are responsible for the regional sea level rise. This paper identifies climate change and global warming as the drivers of some factors causing sea level to rise. The effect of sea-level rise has resulted in the loss of agricultural lands, the destruction of transportation infrastructure, the loss of lands in coastal zones and migration, and the death of some aquatic animals due to saltwater intrusion. In this paper, we reviewed several pieces of literature published between 2017 and 2021 on sea-level rise and the cascading impacts of sea-level rise in various world areas. The papers reviewed borders on the mean sea level rise from different geographical areas on Earth and the monitoring of sea-level rise using different techniques. Some recommendations were also proposed for consideration.

“…Eriksson et al [31] conducted field-based study using GIS software to estimate fundamental conditions associated with the risk of saline water intrusion on the Baltic Sea island of Öland, Sweden. They found out the impact of geomorphological and geophysical parameters on the risk of saline water intrusion and to develop a salinization risk map.…”

The extent of risk is the key measure of sustainable performance of engineering and natural systems and coastal aquifers are no exceptions. Aquifers in the coastal regions are vulnerable to saltwater intrusion (SWI) that attributes to the degradation of freshwater quality in the aquifers. The major factors that influence saline water intrusion are sea level rise due to climate change and the impact of human activities. The water quality erodes rapidly when these factors act simultaneously. Abstraction Desalinization Recharge (ADR) and Qanat-well structure methods are found to be effective methods to mitigate the risk in terms of cost and abstraction of groundwater in specific regions without intensifying saltwater intrusion. Risk management studies are useful to assess the vulnarabilty and economic loss involved in coastal aquifer management. In this paper, a review of risk assessment and mitigation measures of coastal aquifers vulnerable to saltwater intrusion is presented.

“…Small volcanic islands face unique challenges in the assessment and management of their hydrological systems and water resources, which distinguish them from other regions around the world. In small islands such as the Azores, precipitation variation that changes recharge rates and sea-level rise due to climate change will threaten groundwater resources (Comte et al, 2016;Eriksson, Ebert, & Jarsjö, 2018;Ketabchi, Mahmoodzadeh, Ataie-ashtiani, & Simmons, 2016;Werner & Simmons, 2009).…”

Little is known about the spatial and temporal variability of the stable isotopic composition of precipitation in the North Atlantic and its relationship to the North Atlantic Oscillation (NAO) and anthropogenic climate change. The islands of the Azores archipelago are uniquely positioned in the middle of the North Atlantic Ocean to address this knowledge gap. A survey of spatial and temporal variability of the stable isotope composition of precipitation in Azores is discussed using newly presented analyses along with Global Network of Isotopes in Precipitation data. The collected precipitation samples yield a new local meteoric water line (δ2H = 7.1 * δ18O + 8.46) for the Azores region and the North Atlantic Ocean. The annual isotopic mean of precipitation shows a small range for the unweighted and precipitation mass‐weighted δ18O‐H2O values. Results show an inverse relation between the monthly δ18O‐H2O and the amount of precipitation, which increases in elevation and into the interior of the island. Higher amounts of precipitation (from convective storm systems) do not correspond to the most depleted values of stable isotopes in precipitation. Precipitation shows an orographic effect with depleted δ18O‐H2O values related to the Rayleigh effect. Monthly δ18O‐H2O values for individual precipitation sampling stations show little relationship to air temperature. Results show a local source of moisture during the summer with the characteristics of the first vapour condensate. The stable isotope composition of precipitation is strongly correlated to the NAO index, and δ18O‐H2O values show a statistically significantly trend towards enrichment since 1962 coincident with the increased air temperature and relative humidity due to climate change. Results are in line with observations of increasing sea surface temperature and relative humidity.
