The SDR module in the newly released version 3.15 has added the calculation of soil erosion flow (D8). I’m very eager to know how to interpret the output results. Which result should be queried to explain the specific flow direction and flow rate of soil erosion? Looking forward to your reply.
Hi @lichengliu_94,
Thanks for your question. You can find a list and explanation of each of the model outputs in the Interpreting Results section of the User’s Guide. Specifically, you will find the flow_direction.tif output in the intermediate outputs folder. Regarding the flow rate of soil erosion, I think the closest thing InVEST provides is USLE, which is more of a long-term average annual soil loss equation, so I’m not sure if this is what you’re looking for.
Please feel free to look at the User’s Guide and let me know if you have any further questions!
