Hello
I have a question regarding calculation of DEPRESSION storage compartment.
Does DEPRESSION storage compartment exist in all Land Use classes or does it only apply to Wetland HRUs?
When I add the following hydrological processes,
:Abstraction ABST_FILL PONDED_WATER DEPRESSION
:DepressionOverflow DFLOW_LINEAR DEPRESSION SURFACE_WATER
Abstraction method throws me an error if I do not specify DEP_MAX for all land use classes while DepressionOverflow runs with only DEP_K and DEP_THRESHOLD specified for wetland land class.
Also, how does Raven calculate depression storage for simple ABST_FILL? Is it by V = Area (hru) * DEP_MAX ?
Thank you

Re: Depression storage compartment calculation
Depression commands are specifically for the Wetland HRU class.
I believe that abstraction is for non-Wetland HRU depression storage, it basically tells Raven to move water to a different storage compartment. The Wetlands HRU class has this abstraction already built in. I also think that the depression storage in the ABST_FILL volume is just the area of the HRU times the max abstraction depth but other may be able to confirm.
