On assigning hydraulic parameters

A discussion forum for RETC users. RETC is a program which can be used to analyze the soil water retention and hydraulic conductivity functions of unsaturated soils.

On assigning hydraulic parameters

Post by Cansand » Tue May 29, 2007 6:31 pm

hello

1-I am using RETC to predict the unsaturated hydraulic conductivity. Under Hydraulic Parameters
I am entering the the data that I have ( do not need to be optimized) including the value of Saturated Hydraulic conductivity (KS=5E-007 ).
After running the problem, I go to output ASCI file but I find that that KS was given Zero value. Why RETC did not consider my entered KS. Are the optimized cofficients valid in this case.
2- Is there any way where I can copy selected coloumns in ASCI and paste them in format understood by EXCEl cells. This I need because I want to display several curves in one plot

Thanks for help

Thanks for Jikra for reply:
Well I enter the value of Ks =5E-007
but I do not know why the program shows KS=0.
Other parameters are fine (shown as they are entered)

Initial values of the coefficients
==================================
No Name Initial value Index
1 ThetaR .0625 0
2 ThetaS .4000 1
3 Alpha .0170 0
4 n 2.6800 1
5 m .6269 0
6 l .5000 0
7 Ks .0000 0
