Mr. Momo, it is not at all clear what exactly is the problem you want to solve or what are the objectives of your study. Only after this clarification one can help you. Good luck.
The main important hydrological parameters are water temperature, pH, electrical conductivity, dissolved oxygen, free carbon dioxide, total alkalinity, total hardness, nitrite, nitrate, phosphate, etc.
What Mr. Rakesh has given are some of the physical and chemical parameters considered in the water quality assessment and not the "Hydrological Parameters". To some extent the parameters mentioned by Mr. Rakesh can be termed as "Hydro-chemical" parameters.
My dear Mr. Mamo, please don't give so much of home work to the retired persons, who wants to help you. Take some time off and try to explain briefly what you want with respect to your project. Hope you understand and appreciate.
