How to simulate reservoirs in NCAR-reach configuration #769

Open viventus0 opened 1 month ago

Hi I am currently working on simulating reservoirs using reach-based river channels in the WRF-Hydro 5.2.0 system. I understand that WRF-Hydro version 5.1.1 introduced improvements for reservoir simulations specifically for the NCAR-reach configuration (with channel_option set to 1 or 2). However, it appears that these enhancements were not carried over to version 5.2.0.

Without these specific improvements from version 5.1.1, is it still feasible to simulate reservoirs in version 5.2.0? I have attempted to do so, but my simulations have not been successful. The model runs and generates the LAKEOUT.nc file, but there is no inflow or outflow to or from the reservoir, even though there were several heavy rainfall events. Here is how I set up the model:

Could anyone provide guidance or suggestions on how to properly simulate reservoirs using reach-based river channels in version 5.2.0? Any advice would be greatly appreciated.
