Hi Douglas,

Thank you very much for your suggestions. I really appreciate it.
1. I have added precipitation data successfully through Theissen polygon and dfs0 time series.

BTW, when I tried to use Preprocessing Temporal Data to prepare precipitation input, I have to select a dfs2 file for "Model area defined by". Then I tried to added my topography dfs2, but it did not work because the item type is not "Bathymetry". So how can I deal with this problem if I would like to use this tool?

2. For land use, I convert NASS crop data layer into ASC and then converted to dfs2, but when I added it into land use interface, I do not know which item type I should choose. I did not find a type about land use or vegetation.

3. We only have max and min temperature for climate stations. So should we do not calculate snow melt, since we do not have an instantaneous air temperature?

Thank you again and your responses will be greatly appreciated.

Hi

For preprocessing temporal data for precipitation stations, how should I prepare a dfs2 bathymetry file for my model domain?
I tried to generate a new bathymetry file, but could not change the default projection from UTM-30 to UTM-16. And when I imported .xyz files for my stations in the bathymetry file, it did not show up.

Any ideas? And what kind of specific background map should I import to the bathymetry file?

Thank you and your responses will be greatly appreciated.

Hi Dr. Graham,

Thank you very much for your suggestions. Problem has been solved for df2 DEM data. I am a newbie to MIKE SHE and have some more questions about my MIKE SHE model.
1. I have three rainfall gauge stations near my watersheds. I generated a Thiesson polygon for my watershed and converted it into a raster and then to a ASC file. I got error when I used Grd2MIke to convert ASC to dsf2 file. It said "Error reading Input File: ". I have checked ASC file and did not figure out what is wrong with it. And I also tried Time Series Batch Conversion but it has difficulty in reading column for date and time. So what is the best approach to prepare precipitation input from several stations for watershed? Could you please share some examples or template for it (before converted to dfs2)?

2.  I would like to simulate streamflow, and TN and TP at the watershed outlet. And I opened MIKE SHE flow model. BUT i did not found interface to upload land use, temperature and soil inputs to a MIKE SHE flow model. So should I create a MIKE SHE .uzs and .etv model and upload land use, temperature and soil inputs in these models, and then link it with .she model? What is the appropriate way to handle it?

Thank you again and your responses will be greatly appreciated.

Hi Fredrick,

I has the same issue when upload DEM grid under topography menu. Could you please tell me what kind of specific properties you change after conversion?

Thank you,
