DassFlow

A Fortran 2008 MPI parallel computational software initially dedicated to river hydraulic simulation and especially designed for variational data assimilation (4D-VAR). A full second order space and time Shallow Water model has been implemented with a stable parallized adjoint, automatically generated by Tapenade software, to consider real complex topography.
