+Developing the NPD runs and willing to have rivers for the SE-NEMO, we've tested the rivers in MEDUSA-NEMO4.2.2 within the NPD runs (GOSI10)   
+First, the code itself does what we want. just fixed 3 bugs :
+* NPD reads ancillaries in directories (not in the running directory`: "./"`), and that needed a fix [see](https://git.noc.ac.uk/acc/medusa_4.2.x/-/merge_requests/38/diffs?commit_id=5f82188528421c0a4f4eaa9d16f2bff74d0bfefe)    
+* forgot to add the river max depth in the `namelist_medusa_ref`
+* the river nutrient check was in integer instead of REAL 
+
+first runs did not work because of something in the newly made river input files.  
+* tested 1 by 1 seems to come from the N river inputs. but all fields show high values in some specific river mouth, of which some in the Arctic look present very high values (here some example after 5month):
