The SWAT Output gives me the below warnings:
Groundwater ratio may be low
Water yield may be excessive
Surface runoff may be excessive
Especially for the Surface runoff the result is 16400 mm.
What thing i must chech and where?
Never seen something like this with SWAT results. The water balance is totally out of range. How comes surface runoff (16,487 mm) and groundwater percolation (4,743 mm) are many times larger than precipitation (just 532 mm). Seems to be a strange bug, which I have not encountered before. Is there a large surface water body in the catchment (e.g. big lakes, reservoirs) or huge large snow/ice storage? Only those could create something like this in reality. You may like to check the output files (.sub and/or .rch) to see where are these large surface flows - are they on a particular days, do they follow a certain pattern, etc? Same with the percolation values. Such checks may give some clues.
Dear Shreedhar Maskey,
Thank you a lot for your answer. Indeed, there were gross errors in the model, but fortunately I fixed them and I solved the problem with the results.
