Zero flow output

[N Monica]

Dear members,

I successfully ran SWAT using measured data for only precipitation and the rest of the weather data was simulated but the output flow was zero. I checked the reach, subbasin files and they all showed zero values for flow in and flow out.

Where could i have gone wrong and how can i solve this?

I appreciate your responses.

Regards

Monica

How many warm-up years did you allow for the model?  I generally allow at least 5 and sometimes 10 years of warm-up before flows rise to acceptable levels.

I am having a similar issue. Additionally, I am getting some insane FLOWOUT values in the later years of my simulation... over 12,000 cms. Whereas the high end in the earlier years is less than 100 cms. What are the causes and solutions?

Add temperature data also rest of them give simulated

Hello, I have the same problem. I am getting some insane FLOWOUT values in the later years of my simulation. Knowing, I am using measured data for only precipitation and the rest of the weather data was simulated. Please can you help me if you already get the solution. Thx

check your input units for precipitation -- these should be in mm. Also, be sure to have at least 5 years of model warm up .
