Mr. Momo, your question 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.

Mr. Rakesh has given some of the physical and chemical parameters which are considered in water quality assessment and not hydrological parameters. The parameters provided by Mr. Rakesh comes under "Hydro-chemical" parameters".
