What is it?
This feature may be used to assign a hydraulic conductivity (Kxx) values and anisotropy ratios (Kxx/Kyy and Kxx/Kzz) different from those assigned for the rest of the model domain, or even generate a random K field.How to use it:
Constant Value
Check the radio boxes next to ‘Conductivity’ and ‘Kxx/Kyy’ and/or ‘Kxx/Kzz’ to use the values entered the relevant text boxes.Scatter Points
Select this option to import hydraulic conductivity values at discrete points and using spatial interpolation to create a K field. Click the '...' options button to launch a submenu for importing K scatter points into IGW-NET.Borehole Simulation
It is possible to utilzie detailed characterizations of intra-aquifer geologic variability using zone features in IGW-NET. Specifically, IGW-NET can read the results from a Transition Probability (TP) "Markov chain" geostatistical simulations built from detailed lithology borehole records compiled by states/provinces and convert the TP results into a hydraulic conductivity field.Select 'Borehole Simulation' and click the '...' options button to launch a submenu for importing TP simulation results into IGW-NET.
Soon, we will provide a link to a sample input (tecplot) file for Borehole Simulation. If you are interested in using this tool immediately, please contact us at support@magnet4water.net for assistance.
Random K Field
To generate a random (statistically inferred) Kxx field, check the radio box next to ‘Random’. LamdaX and LamdaY values refer to horizontally (east-west) vertically (north-south) oriented correlation scales of the statistically random hydraulic distribution field. Variance represents lnK variance.Click 'Edit' to change any of the input values, or to add another scale of heterogeneity.
