“…Similarly, other studies also revealed the inverse relationship between salinity intrusion length and freshwater discharge. For example, recent numerical studies of Liu and Liu (2014) in Wu River system in Taiwan showed that the salinity intrudes further during dry seasons. Similarly, Rice et al (2012) found that in Chesapeake Bay, the salt intrusion is enhanced in dry periods compared with that of typical periods.…”

Bahmanshir estuary, which is connected to the Persian Gulf, is one of the most important water resources in region. In this study, saltwater intrusion due to possible sea level rise in the Bahmanshir estuary was investigated. A one-dimensional hydrodynamic and water quality model was used for the simulation of the salinity intrusion and associated water quality, with measured field data being used for model calibration and verification. The verified model was then used as a virtual laboratory to study the effects of different parameters on the salinity intrusion. A coupled gas-cycle/climate model was used to generate the climate change scenarios in the studied area that showed sea level rises varying from 30 to 90 cm for 2100. The models were then combined to assess the impact of future sea level rise on the salinity distribution in the Bahmanshir estuary. Using important dimensionless numbers, a dimensionally homogenous equation was subsequently developed for the prediction of the salinity intrusion length, showing that the salinity intrusion length is inversely correlated with the discharge and directly with the sea level rise. In addition, the magnitude and frequency of the salinity standard violations at the pump station were predicted for 2100, showing that the salinity violations under climate change effects can increase to 45 % of the times at this location. This reveals the importance of this type of approach for considering future infrastructure management.

“…Brackish water is mostly found in estuarine areas where seawater mixes with freshwater [8]. Other than estuaries, the elevated groundwater salinity can be observed in the regions where groundwater is in contact with evaporates formations, or mixed with high mineralized and deeper aquifers [9,10].…”

“…Other than estuaries, the elevated groundwater salinity can be observed in the regions where groundwater is in contact with evaporates formations, or mixed with high mineralized and deeper aquifers [8,9]. The discharges from industrial effluents containing dissolved salts, leachates of saline soils and the runoff of salt deposits such as halite or gypsum that is present in the sedimentary rocks also increase the amounts of total dissolved salts and thus lead to the formation of brackish water [10][11][12].…”

Abstract:The problem of limited water supply in the Vhembe District (Limpopo Province, South Africa) is exacerbated by a preponderance of dissolved salts, which cause disagreeable taste and odour in the water as reported by the communities using this water for drinking. The water treatment plant that supplies the treated water to the communities in the District sources this raw water from the Nandoni Dam at the Luvuvhu river catchment. There are no scientific studies that have been reported in the literature that focused on determining the levels of water salinity from various water sources in the municipalities of the District. Water samples from various sites across the Nandoni Dam, a primary source of domestic water supply in the region, were collected through each season over a period of twelve months in order to ascertain the concentrations of dissolved salts in the dam. Onsite analyses of the water samples were conducted using the YSI ProDSS multimeter, while the laboratory water analyses were conducted using the spectroquant and atomic absorption spectrometers. Although salinity tests seem to indicate that the water sampled across most of the Nandoni Dam is brackish during all seasons of the year with the highest being 750 mg/L, water samples from the dam mid-outlet and the treatment plant are slightly below the World Health Organization (WHO) brackish water bracket of 500 mg/L with unfavourable taste for drinking. Results from this study indicate that the water sourced from the Nandoni Dam is not suitable for human consumption and therefore requires integrated water resource management, as well as robust and cost-effective water desalination treatment.

“…These stimulated a major debate on quantifying climate change impacts in coastal regions, and sea level rise has been identified as a primary impact [1]. Various sources have confirmed the historical trends of sea level variations and have projected as high as 2-m sea level rise by the end of this century [2][3][4].…”

Abstract:The participation of individuals contributes significantly to the success of sea level rise adaptation. This study therefore addresses what influences people's likelihood of relocating away from low-lying areas in response to rising sea levels. The analysis was based on a survey conducted in the City of Panama Beach in Florida (USA). Survey items relate to people's risk perception, hazard experience, threat appraisal, and coping appraisal, whose theoretical background is Protection Motivation Theory. Descriptive and correlation analysis was first performed to highlight critical factors which were then examined by a multinomial Logit model. Results show that sea level rise awareness is the major explanatory variable. Coping appraisal is qualitatively viewed as a strong predictor for action, while threat appraisal is statistically significant in driving relocation intention. These factors should be integrated in current risk communication regarding sea level rise.
