Discussion with Helene: There is already function that converts flow direction into geodataframe. check the below documentation. Then the convertion into graphs can an easy next step. https://deltares.github.io/hydromt_wflow/latest/_examples/prepare_ldd.html
Discussion with Helene: During this step, add flag: lines that are added (approximate), lines that are from the vector layer. knowledge about percentage of reliability, give indication to the user how much work still needs to be done. e.g. 50% guessed, that means a lot of follow-up dataset work is needed (useful for proposal estimation) the artificially connected line, we can condition on the length which gives estimation of uncertainty.
1st draft (updated on 18--8-2023) A function that is called 'setup_graph_from_hydrography` is drafted. This function reads the hydrography data and get flow direction as a graph.
