Dear Group
I am doing a study on the effect of olive mill waste water on soil transport properties under un saturated condtions. I did a leaching experiment using inert tracer (Br) for 10 days and I took samples to measure Br. I want to draw BTCs and calculate D and V using STANMOD. I tried many times but no good fitting to the original data.
The input file is
