“…Saline groundwater occurs underground in unconfined coastal aquifers at a depth ( z ) below sea level of about 40 times the height ( h f ) of the fresh water above sea level: z = 40 h f (Todd & Mays, ). According to Sherif and Singh (), when the level of the Mediterranean Sea rises by 0.5 m, seawater intrusion will influence areas up to 9 km from the coast. Moreover, Werner and Simmons () demonstrated that seawater can intrude up to 5 km from coastal areas through seawater‐intrusion boundary simulation.…”

Coastal areas are being increasingly damaged by the expansion of seawater‐intrusion areas. This study suggested a three‐step method to prioritize the countermeasures adopted to reduce the areas affected by seawater intrusion. First, the most vulnerable area to damage from seawater intrusion was selected among 25 areas on the western coast of the Republic of Korea using three multicriteria decision‐making (MCDM) methods. As a result, Taean‐gun was selected as the most vulnerable area for seawater intrusion. Second, a numerical model called SEAWAT was configured to predict the areas where seawater intrusion could potentially occur. For future scenarios, Representative Concentration Pathways (RCPs) 4.5 and 8.5 were used as the sea‐level rise scenarios. To predict the future use of groundwater, the future groundwater extraction rate was predicted using a linear regression of the groundwater‐use data over the past 10 years. As a result, it was predicted that 68.5% of the total Taean‐gun area would be affected by seawater intrusion for RCP 8.5 and current trends in groundwater use. Third, the effectiveness of the measures adopted for the reduction of seawater‐intrusion areas were analysed by considering the projected future scenario and the local characteristics (including the total population, population density, groundwater‐level distribution, salinity distribution, groundwater‐use characteristics, and ground‐elevation distribution) of the Taean‐gun district. After considering the effects of the countermeasures adopted for the different locations in Taean‐gun and the data related to seawater intrusion, the priority areas for applying countermeasures against seawater intrusion were determined using three MCDM methods. It was concluded that the Taean‐myeon is a priority area for applying countermeasures.

“…Climate change is a topic of huge interest for scientists, stakeholders and the public, due to its long‐term direct impacts and consequences. Many researchers reported increasing temperatures for the 20 th Century (Sherif and Singh, ; Shaver et al ., ; IPCC, ; Dong et al ., ; Xie et al ., ) and an increase from 1 to 3 °C is predicted for the 21 st century (Stavig et al ., ; IPCC, ). The ongoing global warming (Haeberli et al ., ; Kargel et al ., ) is triggering global consequences and it is likely also to alter natural systems at the local scale.…”

Climate change is a topic of enormous interest due to its direct impact and long-term consequences. The ongoing climate warming is triggering global impacts and it is likely to alter natural systems at the local scale, too. The observed climate variability in the Romanian Carpathians has been tackled by several researchers and the negative impact of climate change on groundwater vulnerability has also been assessed. A temporal analysis of four climate indices (De Martonne, UNEP Index, Johansson Continentality Index and Pinna Combinative Index) and crop evapotranspiration over the past 50 years was performed to understand the climate trends in the Beliş district, to estimate the effective precipitation in the area and to assess the effects of climate change on groundwater resources. Land cover data were extracted from satellite images and crop evapotranspiration data were evaluated based on field co-efficients. An examination of the climate index trends and change points was carried out using the Rodionov test. In the study area, the climate indices indicated very humid and marine climate conditions. At the same time, it was noticed that the crop evapotranspiration values increased from 1961 to 2013 and the annual effective precipitation ranged between 200-300 mm. In order to understand the impacts of climate change on groundwater resources, an innovative method was proposed using an inference matrix that combines the climate indices and effective precipitation. Based on this method, the climate indices and effective precipitation for four decades indicated a low impact of climate change on groundwater resources in the Beliş district.
