The algorithms (e.g. the variational formulations, dedicated regularization terms, 1D-2D integrated solvers, assimilation of lagrangian data etc), the equations (shallow flow models which may be originals), the numerical schemes implemented into the various versions of DassFlow are detailed in the articles mentioned below.
