Times series precipitation for input

Good morning.
I’m trying to simulate GROUNDWATER_FLOW on 3D domain which is similar to Ammer catchment in “Computational Hydrology 1”.
On page 70, groundwater recharge rate is implemented as source term for each node in “.asc” file.

Here’s the question.

  1. I want to assign the annual sum of groundwater recharge with varying values each year as a time series. I understand that this can be implemented using #CURVE in the .rfd file in OpenGeoSys. If possible, could you explain how to use this?

  2. If, I set the time unit to DAY in the .tim file, do I need to match the scaling factor accordingly in m³/day?

I am sincerely hoping for someone to respond. It’s disappointing that no one replies or gives advice whenever I post.
