Error with irrigation canal delieation and units in SWAT+ Editor

[Lukhmon Dadojonov]

Dear SWAT + Editor community.

I need your assitance in clarification of few point, which I encountered during a watershed deliation and running the model.

My first question is about irrigation canal delineation. So in my project an irrigation canal by reason of DEM  ( ALOS PALSAR, with res 12.5 m  ) inconsistency for deliniating man-made features was incorrectly created in QWAT+, so it was cretaed with reverse slop from the river to reservoir, hence canal entering point into reservoir has been identified as outflow point instead of inflow point . What solution will be correct to fix it? Changing parameters of the channels through SWAT+ Editor?. But if so there will be a lot of manual works. Isn't it?. I already tried to fix it via delineation process by burning canals into the DEM for changing the slope, but it wasn't so much efficient. Does theare any idea how it can be done and what is standard approch on such cases?

Look to the enclosed screenshots, direction of the flow shown with arrow.

My second question directly relates to the SWAT+ Editor units for the resrvoirs.

Actually, I have some concerns about resrvoir changing parameters. So, in GUI of SWAT+ Editor the area unit indicated in hectars, though when you opening it initally it shows area in square meters. If my watershed area is 600 hec, then what I have to assign to the value of "Reservoir surface area when reservoir is filled to principal spillway" should it be in square meters or in hectars?

The same about volume of water,  in the watershed on which I am working the maximum water storage capacity is 90 mln cubic meters. If to foloow the interface description the volume of the water should be entered in 10^4 m^3 but again when you opening SWAT+editor first time it shouws you water volume in m^3. So I am abit confuced.

Any guidance and suggestions will be very appriciated.

Thanks in advance!
