Hi, I’m Xiao. I had a problem running Delineatelt. [微信截图_20220313101555] [微信截图_20220313101741] [微信截图_20220313101706] It has been running for a long time, but there are no results. Just like this. I do not know how to solve it. Please help me. [微信截图_20220313101913]

Hi @Xiao_Zhang - That does seem like a long time to run, but it also looks like your DEM might be over 1GB in size. The larger (or finer-resolution) the DEM, the longer it takes. The screenshot of your Workspace looks like DelineateIt finished the first step (filling sinks), and was still working …

You’re right. The DEM was more than 10 GB. I’ll try again. Thank you.

Hello, can I divide the DEM into several parts and then use DelineateIt to calculate the watersheds, and finally merge several watershed maps together?

[微信截图_20220315214926] I have encountered another problem. The result of operation seems different from the watersheds map required for annual water yield. How should this be solved?

Hi @Xiao_Zhang , The Annual Water Yield model requires that the watershed features have an unique ID attribute called ws_id. DelineateIt does not make the ws_ids. You will need to add this attribute in your GIS software. Does that answer your question?

Thank you. Do you have relevant instructions for this operation? My GIS knowledge is poor. :sob:

DelineateIt does create a field called id, so you can just rename that to ws_id. Instructions for QGIS: Open the watersheds file in QGIS Right click on the watersheds layer in the Layers sidebar, then click on Properties in the menu that appears Go to the Fields tab Click on the pencil icon to tur…

Thank you very much, I will have a try.

Hi, I can not generate the sub-watershed automatically. The model completes the process but only generates the watershed. The generation of sub-basins automatically (high density or low density), should be done based on the flow accumulation and snap distance. [Captura]
