The effect of Rainfall, Temperature and Humidity on Saline in the Southern area of Bangladesh

A study was taken to measure the effect of rainfall, temperature and humidity on salinity area as well as to project the future trend of increasing saline area in the southern area of Bangladesh. Patuakhali district was selected as study area for the study. Secondary data such as temperature, saline area, relative humidity, rainfall, etc. were used in the experiment. The results showed that minimum temperature and relative humidity has the positive effect whereas rainfall and maximum temperature has the negative effect on decreasing the soil salinity. The study projects that the saline area would be increasing trend in future. Therefore mitigation measures could be taken to prevent the salinity in the coastal area.
