Interpreting SDR results
I have run the SDR-INVEST model, after building some scenarios in RIOS and I have problems analyzing the results.
1. When I see the results of the table of attributes in shapefile of sub-basins, which according to manual their units are (tons / watershed) for the three scenarios created more in base scenario, I see results in thousands and they seem unrealistic. Are those tons or kilograms? When analyzing the logic of retention and sediment export in the different scenarios, it is logical to increase and decrease according to the scenarios, but the units cause me a lot of doubt (see table in summary sheet, attached with the summarized modeled scenarios)
2. When analyzing the values of sed_export.tif and the sed_export of the resulting sub-basin shape, there are differences, in this case for "sub-basin 2" of 1154. Does the second include some deposition factor because it is higher? See attached table (sheet 2)
3. To compare the results of SDR / INVEST with other data of hydrological models that I have (SWAT), for the same sub-basin, I have doubts as to how to adjust them properly, or if I have to do it with this data (see sheet 2 in attached Excel sheet) )
4. After clarifying the above, I would like to calculate the ROI, since I have replaced my investment portfolio built by RIOS, in one of the modeled scenarios and I used the following formula initially. (see table Summary sheet in columns ROI and its formula)
Total benefit = (protection export - baseline export) + (protection export - unprotected export)
Are these results logical up to now?
I will be very grateful with your help
