Abstract: A dye dispersion study conducted for the study reach during low flows has been resolved to provide information on the dispersion coefficient (DL) of the Hindon river. Logistic reasons often constrain the field study for this parameter, considered crucial for any water quality modelling study. It, therefore, becomes imperative to identify, amongst several empirical formulas, the most appropriate formulation for the site specific area. In the present study, the classical methods have been used to identify the McQuivey & Keefer (1974) and Liu (1977) as the most suitable empirical relationship for estimation of DL for Hindon river reaches, for which field study was not practically possible.
