[RegCNET] the runoff simulated by RegCM4 reached negative value

[Huanghe Gu]

Hi all,

I found the runoff  in SRF.* in some part of the area reached negative value. I think it is irratonal in hydrological simulation. Other variables like temperature, precipitation and evapotranspiration were normal.  Has anything like this ever happened to you? How should I solve this problem?
The land surface scheme I chose in RegCM4 was "BATS". 

Thanks.

Regards,
Huanghe
