Hi

I have the following questions regarding modelling unsaturated flow using Richard's equation
My model is a simple 2D assuming some amount of mean daily precipitaion infiltration through the top boundar of the model. The other three boundaries are all closed or a non flow boundary conditions. I have set up all the variables and necessary parameter. And i have found the velocity of the flow, which is my target. But the velocity display is dependent on different times. What does the times mean and what unit do they have? min, second or days?


The other question is that, is the velocity i obtained dependent on the areal size of my system?.


Thanks for help
