ABSTRACT=The South-western coastal areas of Bangladesh are highly exposed to salt water inflow due to cyclones, and are therefore expected to deteriorate over the next century due to climate change. So, this study indicates that what is the geochemical of salt water and connected compounds, the reaction to salt water inflow in river systems, and the parts likely to be impacted by storm water flooding under current and 2100 circumstances? Moreover through primary soil and water sample this study highlights status of salinity in SWCRB.In this investigation, water and soil samples were collected from the most sensitive unions of Shyamnagar Upazila, Gabura, Burigoalini and Munshiganj adjacent to the Bay of Bengal and the samples were tested by the laboratory of the Soil Resources Development Institute (SRDI). Particular carefully chosen parameters for the soil - pH, EC, OM, TN, P, Ca and K - and the water - pH, EC, Na, Cl- and Bicarbonate - were examined to analyse the impact of salinity.  Moreover, primary water salinity statistics were obtained from the three key water current locations of the Bangladesh Water Development Board (BWDB), neighbouring the investigation region. Furthermore, a Digital Evaluation Model (DEM) was used to guess the salinity induced by storm gushes in the corresponding impacted zones. Analysis exhibited that EC, pH, Na+ and Cl- of water and EC, pH, OM, TN, Ca2+, K+, and P of soil were all found to be higher than the recommended values. The EC of water was found to be highly significant with Na+ and Cl-; Na+ and Cl- showed a highly significant correlation among them also. Similarly, soil OM was found significant with EC and highly significant to be with TN. Potential storm gushes circumstances from 1 to 9 metres can impact 1 to 33% of the nation and 6 to 97% of the Shyamnagar Upazila, and in 2100 could impact 1 to 38% of the nation and 9 to 93% Shyamnagar Upazila section. Nevertheless, the forecast for cyclone-related storms will increase significantly and may make cultivation and stable settlement in the Shyamnagar Upazila region very challenging and salinity will intensify.
