Better Water Resources Management: Part 2

Groundwater Recharge Rate Estimation using 1D Unsaturated Numerical Model

   Watch Promo

Understanding Groundwater Recharge Rate is essential for the successful Water Resources Management and Contaminant Transport in Subsurface.

Why 1D numerical model? Because simple empirical models do not include changes in nature during the time or conditions they were underpinning the assumptions in empirical equation - increasing water table depth, change of land use, climate changes...

After this course you are going to be able to set up monitoring network for soil moisture and potential, model rainfall infiltration and its movement in deeper part of vadose zone where eventually it will become groundwater recharge.

So you are going to be able to precisely determine groundwater recharge rate and include it in Water Resources Management of your region.

Course Topics:

  • What is soil texture and how to determine it quickly
  • In depth explanation of soil water content and soil water potential
  • Devices to measure volumetric water content and soil water potential
  • Installation and maintenance of devices measuring volumetric water content and soil water potential
  • How to determine soil water retention curve - basis for getting unsaturated hydraulic parameters for numerical model
  • Getting unsaturated hydraulic parameters from soil retention curve
  • How to set up 1D numerical simulation of soil water movement including ol hydrological water balance elements
  • Groundwater recharge rate determination

Who should attend?

This course is ideally suited for hydrogeologists, environmental engineers, climate change experts and all others who wants to dive into the use of unsaturated numerical models to make informed decisions about water balance of the region and contaminant movement from ground surface to aquifers.


B.Sc in hydrogeology, geology, environmental engineering, agriculture, civil engineering....

Time Commitment:

Average 2 - 3 hours per week to finish each Module. We encourage you to spend time with the course each week. Your focused attention will pay off in the end!

If anything seems unclear or you just have a question, then please let me know - I will get back to you as soon as possible, usually less then 24 hours. After each lecture you have place to ask questions. Again, thank you for joining me on this course.

What is new related to this 100% online course (15.3.2020)?

We added great new reference peer review paper that that will enable you to see how this course can be applied in regional Water Resources Management where increased water depth due to overdraft happened and climate elements change causes changes in groundwater recharge of aquifer and the whole region water balance.

Happy learning!

Dragan Kaludjerovic, PhD
Dragan Kaludjerovic, PhD

Dragan Kaludjerovic received his BSc, MSc an PhD at Belgrade University and he is currently at online specialization at The Johns Hopkins University - Environmental Engineering.

In his early career, 1998, Dr. Kaludjerovic focused his research on more complicated numerical models such as unsaturated zone modeling and transport modeling with MT3DMS. Feedback from his presentation at the MODFLOW 98 Conference influenced him to continue to work on mathematical models and their application to hydrogeology engineering which resulted in his MSc defense.

Later, in 2000, he was invited to work at Waterloo Hydrogeologic Inc, (WHI), a world leader at that time in groundwater model software development and consulting. During his time at WHI, he was introduced to innovative modeling techniques, including PEST for parameter estimation and reactive transport modeling with RT3D.

During the next several years, Dr. Kaludjerovic worked on numerous projects including the design of a large groundwater source with 1000 l/s in Macedonia.

In 2005, Dr. Kaludjerovic started work on his PhD thesis which was completed in 2008 and titled "Natural Attenuation of Contamination in Groundwater". The scope of this thesis focused on applications of the RT3D (Reactive Transport) model with multiple electron acceptors to a field case (aquifer contaminated with xylene).

After his PhD thesis, Dr Kaludjerovic continue to conduct research in the area of aerobic and anaerobic bioremediation with emphasis on emulsified oil projects and gas infusion technologies. During his carrier Dr Kaludjerovic published more then 25 papers which can be found below or on his Linkedin page.

In last several years, Dr Kaludjerovic is working with high resolution satellite images (both optical and radar satellites) and its application in environmental science and modeling.

What our Clients Say About Us

Dragan is a fantastic technical resource. With his assistance, I’ve been able to greatly improve my groundwater modeling and GIS skills. I will continue to seek him out for my professional development needs. He provided great value and was a pleasure to work with!
- Bob Marley - Senior Hydrogeologist at EA Engineering, Science, and Technology, Inc., PBC

I have known Dragan for many years. I am most impressed with his dedication to hard work, and the breadth of his knowledge on environmental data acquisition and processing, software, and modelling.
- John Doherty Owner, Watermark Numerical Computing, Australia

He is always available for questions and truly goes above and beyond in his training classes. I have gained a lot of knowledge over a short period of time working with Dragan and would highly recommend his services to others.”

- Thomas Ballard, PG, CHG, Consulting Hydrogeologist, USA

I took multiple training courses with Dragan. I learned a great deal with him during each of the courses. He is an excellent teacher willing to help out in any way possible.
- Mark Sherrill, Environmental Scientist at Short Elliott Hendricson, USA

"I recently completed a course in Remote Sensing and QGIS with Dragan. He was very knowledgeable and guided me through the theory and background and also the implementation of remote sensing. He was very personable and happy to answer all my questions. I appreciate having him as a reference and would recommend him to anyone interested in this topic."
- Lea Bergwall, GIS Analyst, USA
