Abstract
Current research was performed to find out the relationship between temperature, rainfall, and salinity gradients in pond, canal, and river water together with deep tube well water of Khulna, Bangladesh. Temperature showed an increasing tendency and rainfall showed the decreasing trend with time. Water was collected from Batiaghata, Dacope, and Koyra Upazila. A total of 51 water samples were collected to determine electrical conductivity, salinity, and the concentrations of calcium (Ca) and magnesium (Mg). The concentration of the mentioned parameters was very high at different points as compared to the standard value set by Bangladesh Bureau of Statistics and World Health Organization. Salinity was the highest in the southern part and was the lowest in the northern part. The river water contained the highest salinity, and pond water contained the lowest. Salinity trend could be ranked as river water ≥ canal water ≥ deep tube well water ≥ pond water. The study could be very effective to know the present scenario of salinity and to find out further effective solution in this region.
