People & ContactsDassFlow (Data Assimilation for Free Surface Flows) is a computational software originally developped at INSA Toulouse / IMT (from a former version at IMAG Grenoble) is now developed in a few institutes / corp.: INRAe, INSA-IMT, CS Group (see the complete list of collaborators below). Your contacts
K. Larnier, Eng. CS group (developements, validations, datasets; since 2017), P.-A. Garambois, Res. INRAE (hydrology, hydraulics, applications; since 2017), L. Pujol, Eng./PhD ICUBE Strasbourg (coupling, wrapping, applications; since 2018), L. Villenave, Eng./PhD INRAe (wrapping, applications; since 2021), J. Monnier, Prof. INSA Toulouse (equations, methods, hybrid A.I., architecture; since... long). The GR4 hydrological model which has been integrated into DassFlow has been developed by L. Santos and G. Thirel from INRAe, HYCAR research Unit. Current applications & significant resultsRiver flows modeling 1D St-Venant, 2D shallow-water, low-complexity (0.5D); coupling with rain-fall models.The codes are written in Fortran (MPI for 2D model) and Python. Features: Inference of the river properties (discharge, bathymetry, friction) from available observations. Significant result: the HiVDI algorithm; discharge and bathymetry estimations from altimetry data (e.g. from the forthcoming SWOT mission). See e.g. poster 1 and poster 2 from AGU dec. 2018. See also the SWOT mission website (NASA-CNES). Ice flows modeling Classical 2D shallow ice flows models (xSIA, SSA), original ones (RU-SIA, SMISA) and 3D ones (Stokes). Power-law fluids. The codes (written in Fortran and Python) are experimental codes aiming at assessing new asymptotical models, numerical schemes and original inversion methods. These computational codes are interfaced with public ice-sheet data sets: altimetry, InSAR, bedmaps, climatic source terms. Significant result (INSA-IMT): estimations of the bed topography elevation inland East Antarctica Ice Sheets (EAIS) areas from surface satellite data (altimetry, InSAR). See e.g. SWOT mission website (NASA-CNES). A few know-hows of the VDA methodology have been transfered to ISSM team developers (UCI - Nasa JPL, USA) too. Complex flows modeling e.g. lavas (Herschel-Buckley type rheology). 2D shallow (lubrication type model and SW type model) are designed for "virtual rheometry" (identification of rheology parameters). Joint work with Univ. Canterbury, New-Zealand (Marsden project). In progress. Greetings to the great former contributors, developers of DassFlow !
