Hello all,

i am new to water chemistry, i have been looking at trends in the water chemistry parameters, and found there is significant decreasing trend in Stream-water temperature, Ca, Mg, Na, and chloride along with discharge both in the monsoon and non-monsoon seasons.

Like From Jan 1994, Jan 1995, Jan 1996...... Jan 2018 (for Non-Monsoon period) Sept 1994, sept 1995, sept 1996...................Sept 2018 (Monsoon period)

Note- watershed (1000 km2 drainage area, Western Ghats, India) is free from dams and other water structures.

What could be possible drivers of trends in the above parameters?

Please provide your valuable suggestions.

Thanks in advance.

Regards

Rajat
