This paper reviews the estimation methods developed and used in India for low-flow, long-term mean flow and flood characteristics. The review is intended to provide a quick reference guide for such methods used for hydrological prediction in ungauged basins. As such it lists identified estimation formulae for various parts of India with necessary parameters. The paper also effectively gives a quick assessment of the status of hydrological predictions at ungauged sites in India. Few studies focusing on low-flow estimation at ungauged sites have been identified.
