Shaun You will need to run FEFLOW in solute transport mode that incorporates advection and dispersion. You will then need to set the density factor to a value...
Shaun Further to my earlier email - you should apply a flux constraint to the solute boundary so that water entering the model has a specified salinity (as...
Dear Member, Can you please refer me to any relevant literature (case studies/papers/web resources) pertaining to unsaturated and saturated groundwater flow...
Hello Everybody, My name is Pejman; I am doing my master thesis on geothermal modeling inTuebingen, Germany. I appreciate it if somebody can help me. I have to...
Hi Pejman & others, The most effective and efficient method for running successive models in FEFLOW is thorough the batch or command line mode. You'll need to ...
Can also use PEST to automate certain tasks. FEFLOW comes with version 4, which may be sufficient, or download newest version from www.sspa.com. PEST...
I've noticed that the time-varying parameters in the FEM file (under MMLIST), at least some of them, are also in different units; K values are in the 1e-4 m/s...
Dear all... My name is Murugan doing PhD in Department of Geology, Anna University, Chennai, India. I want how to give data for Flow Data and Transport Data...
We are currently exploring methods of improving the representation of evapotranspiration in FEFLOW without having to use the unsaturated zone package. Has...
hi, Is there any option to correlate the land use change and the pollutand distribution directly in feflow? rt now im doing a project on "study of landuse...
Hi Gio Thanks for the response. There are several options in FEFLOW to provide a flux of water from the water table. However to represent evapotranspiration...
There is no such option. You have to do this yourself, especially since its a site-specific correlation. There is no other web site I know of. *Pete Sinton* ...
You can now use arbitrary expressions for recharge calculation in FEFLOW. On http://www.wasy.de/english/produkte/feflow/howto/video_evapotranspiration.htm you...
Indeed there is no direct way in FEFLOW to do this, so you'd have to define boundary conditions for flow and transport manually. If the landuse change...
Maybe you already knew: on WASY website there's a movie about setting ET dependent on depth to groundwater. You don't need to use the unsaturated module. ...

I've modeled underground voids and lakes in FEFLOW using the method you describe. I know of no better approach in FEFLOW. There are modules for MODFLOW that...
Thanks for your response Peter. We have had no success with the MODFLOW Lake package - it just seems to create numerical instability. Regards Brian ... you ......
