Head prediction during drying season

Post by Sasan » Mon Sep 16, 2019 3:50 pm

Hi

I have a soil column that has total depth of 120 cm. I have measured the change of water content and suction at depth of 70 cm using sensors. I want to predict the change of pressure head (suction) at depth of 70 cm during drying season. The time of prediction is from the end saturation process (beginning of drying process) to the maximum drying point (corresponding to suction = 450 kPa). What upper boundary, lower boundary, and value of hCritA do you recommend? Thank you in advance for your help.

We can't advise you on that. That will depend on your actual conditions. J.

The entire depth of slope is 120 cm. I used water content and suction measuring sensors in two depths, 30 cm and 70 cm. During measurements, I saw a spring coming out of the slope. However, I did not see water inside the holes that I dug for sensors (it should be noted that, the measurement started at 5/8/2015).
