SDR model v.s. Sediment retention model
In the Sediment retention model found in InVEST v3.0.1 and earlier, the total retained sediment has two parts, which equals to the sum of the sediment removed by the pixel itself and the sediment removed through routing filtration.
But in SDR model found in InVEST v3.1, it does not account for the retention from upstream sediment flowing through the given pixel?
So if I want to map the ecosystem service of soil retention, it would better to use the Sediment retention model found in InVEST v3.0.1 and earlier, in order to accout for the two parts, which just like the eqution in the attached image?
Thanks a lot.
