Of course, the conservation of the water balance is not assured after state updating in hydrological modelling.

Alternatively, the update of model parameters, or of model forcing (e.g. precipitation) can be considered.

Several examples have been already published, mainly in recent years.

Good luck with your research,

Luca

If I want to do this study with SWAT for a small watershed then What are the computational requirements?

ask to Wade Crow and/or Fan Chen, they made a study with SWAT and the EnKF:

Chen, F., W.T. Crow, P.J. Starks and D.N. Moriasi, "Improving hydrologic predictions of a catchment model via assimilation of surface soil moisture," Advances in Water Resources, 34(4), 526-536, 2011.

send them an email, they will surely answer you with all the details.

Thank you so much Dr. Luca for your valuable insights for my learning process
