Variable number of soil layers for each HRU
Posted: Thu Jul 01, 2021 4:40 am
Hello everybody,
i am quite new in Raven. Our research team would like to build the raven model for a catchment, which is already modeled with another watershed model. So with the goal of model intercomparison.
My first question adresses the number of soil layers:
Our catchment is divided into subbasins and HRU's. And each HRU has a specific number of soil layers with variable depth. Is it possible in Raven that the HRU's have a different number of soil layers (eg. 3-11) ? And how is it implemented in the raven-files?
And my second question: Has Raven the ability to model preferential flow along soil macropores from top soil directly to groundwater? In the manual I found "split process". We want to set a volumetric percentage of preferential flow for each HRU and soil layer (or it's calculated from soil layer attributes).
Thanks!
