Questions about the nutrient delivery ratio model
I followed the users's guide to prepare the data for running the nutrient delivery ratio model.Though the coverage area of DEM is bigger than my study area,one side of my study area is facing the sea.The coverage area of others data inputs are the same as my study area.After running the model many times to have a suitable threshold flow accumulation value by comparing the stream.tif output with the stream line of my study area,I got a stream map that can almost match the stream line of my study area. But the outputx_export.tif is odd.The coverage area of it is smaller than my study area.The value of the raster matching the stream is null. The missing part of the study area is mainly distributed on the edge of it,especially the side of the part facing the sea. So could you help me deal with this？The missing part is green.
Looking forward to your reply！
