EduVideos

Dear Students,

due to the coronavirus infection epidemic I started to produce some eduational videos to show you the steps of building models in Processing MODFLOW. 

You should know that these videos were made using tools we have and not using the abilities of professional studios. I am sorry for some aborted sentences, some loud barking of my dogs, boring parts, etc... I hope that the videos will serve the better understanding of modeling steps. All videos are converted and saved into the most compressed Matrjoska *.MKV format. You may use VLC or other codes to open them...

I was using Processing MODFLOW version 8.0.47, but even using v5.3.3 you can do ther modeling tasks. I did the task always keeping in mind the limitations of the educational/demo version of PMWin 8.0 software.

You will need a user name and a password for downloading that will be provided you using the university's educational system (Neptun).  Using the password you will be able to visit the ftp site of the department (ftp://193.225.60.133/) and you can download all the files from the directory GWFlow_Modeling (keep in mind that normal letters and capitals are not the same on this server!) You cannot delete or modify, only download is allowed!

I will also publish the datasets on the server in a separate directory (GWFlow_Modeling_datasets). Since videos and datasets forms a huge amount of data, I can make the files available from afternoon 23/03/2020 due to bandwith problems!

Dowloading the videos is free to everyone... even if they are not my students, not students, etc... please use it on your own fun! I did them quite quickly so there might be some minor mistakes in it, but I hope that the general aim to help your studies is succeeded.

To avoid sending passwords to everyone I decided also to publish all videos on google drive. The links below are connected to this google drive!

 

Video #0. General features of PM - introduction

Video #1. Building a simple model in PM 

This video shows how to build a simple steady state model with a production well and two injection wells in a single layer phreatic aquifer. It shows how to: make and refine grid; use local coordinate systems; define fixed head boundaries, hydrogeological parameters; define a parameter of one cell, and how to copy it into other elements; define the matrix elements of a homogeneous field (reset matrix); use the well package; make a contour map of any input data-field or the resulted vaues; and finally how to run MODFLOW model and what are symptoms of convergence of iterative solutions

Video #2. Drawing pathlines from and to the wells based on Video #1

This video shows the usage of PMPATH software to draw pathlines and to make forward and backward particle tracking using single particles and particle sets

Video #3. Building a 3D steady state model with recharge from precipitation and a horizontal flow barrier (slurry wall, impermeable retaining wall., etc.) based on Video #1. 

Video #4. Adaptation of rivers and drains to models based on Video #3. Some explanation on whiteboard and a screenshot of the whiteboard.

Video #5. Using General Head Boundaries (GHB) instead of Fixed heads based on Video #3. Some explanation on whiteboard and a screenshot of the whiteboard.

Video #6. Implementation of GW Flow (horizontal hidraulic gradient) into the model based on Video #3.

Video #7. Application of inactive zones and using the import results command to determine real drawdowns based on Video #6. 

Video #8. Defining zones instead of homogeneous parameter fields based on Video #5.

Video #9. Using interpolations, building irregular 3D  geometry based on Video #3. Some explanation on whiteboard and a screenshot of the whiteboard.

Video #10. Building a transient model with observation wells, making animations. Some explanation on whiteboard and a screenshot of the whiteboard.

Video #11. Using time variant specified heads to simulate a river flood based on Video #10. Some explanation on whiteboard and a screenshot of the whiteboard.

Video #12. Building  a model of vertical profile - Joe Toth's Unit basin model Some explanation on whiteboard and a screenshot of the whiteboard.

Video #12 nested . Building  a model of vertical profile - Joe Toth's Unit basin model with nested flow regime (based on Video #12)

Video #13. Building a multi-species transport model with three different  contaminants , different source types. Natural migration of contaminants. Some explanation on whiteboard and a screenshot of the whiteboard (planned but still missing).

Video #14. investigation of remedial strategies I. (slurry-wall and slurry wall with well) based on video #13

Video #15. investigation of remedial strategies II. (active well line, drain). the use of water budget calculator based on video #13
