Infiltration

[sazanavi]

Hello,

i have double ring infiltrometre (30*60) to measure infiltration rate, im planing to get soil tensiometer to measure initial and final water content.
Can i get infiltration rate with initial & final water content and unsaturated double ring inf test

Anyone can help me to model this situation

Best Regards, Thank you

If you are new to HYDRUS modeling, you should do some of the tutorials:
a. either those posted on the HYDRUS-1D website (http://www.pc-progress.com/en/Default.a ... -tutorials),
b. or from the CSIRO Tutorial eBook: https://www.pc-progress.com/Downloads/P ... 0_2018.pdf

Thank you Jirka,

I have check all them, it is very usefull for me. But still i couldnt get how to calculate infiltration rate with soil moisture & double infiltration test data

how can i fix the issue

Thanks, regards

Since the flow in this experiment is not one-dimensional, you need a two-dimensional (and its axisymmetric option) model for the analysis of the double infiltration data. J.
