Abstract. The Upper Ganga Basin, Uttarakhand, India has high hydropower potential and plays an important role in development of state economy. Thus, knowledge about water yield is of paramount importance to this region. The paper deals with use of contemporary water yield estimation models, such as the distributed model (InVEST), Lumped Zhang model and their validation to identify the most suited one for water yield estimation in this region. Earlier, while utilizing these models, attempts were made to consider a single value of some important model parameters which in fact show a variation at a pixel level scale. Therefore, in this study, the pixel level computations are performed to assess and ascertain their need in model applications. To validate the findings, the observed sub-basin discharge data is analyzed with the computed water yield for four decades, i.e. 1980, 1990, 2001 and 2015. The results obtained are in good agreement with the water yields obtained at pixel scale.

Short summary
In this study, we draw a comparative evaluation of water yield using two approaches Lumped Zhang model and Pixel based approach. Even in pixel level computations experiments are made with existing models of some of the involved parameters. The study indicates not only the suitability of pixel based computations but also clarifies the suitable model of some of the parameters to be used with pixel based computations to obtain greater results.
