Weak constraint data assimilation involves a certain number of weighting and smoothing parameters. The authors present an approach to estimate them based on maximizing the entropy. Because application of this rigorous scheme to large-dimensional data assimilation problems is a tedious task, the authors also consider a simplified version of the entropy method, which assumes maximizing a data cost as a function of relative data weights. It is proven to be equivalent to maximizing the entropy under certain assumptions. In the scope of this method, the authors have also proposed a smoothing procedure necessary for very fine grids. The schemes have been checked using a tidal channel model for Tatarsky Strait.
