Setting of Unsaturated Hydraulic Condictivity Function



You can select one of four hydraulic condictivity functions:

button
By clicking here, the function is drawn in a graph. You can check if you inputted appropriate values. Text data file ([soil name]_uhc.txt) which holds hydrailic conductivities at discretized water contents is created in the same folder as the case file.

In case of Inverse Parameter Estimation
Unless you set somewhat close value as optimum ones, it may take long time to converge or sometimes the iteration stops due to extraordinaly value. It is recommended to load soil property file for similar soil.
  • "Fixed" checkbox
    Parameter with checkbox at the leftside can be fixed during the inverse parameter estimation.
