Our new webinars - 2018

Building better groundwater models - calibration is not enough anymore

Building a defensible model requires calibration as necessarily step in groundwater modeling workflow. Usually modeler divides model area in homogeneous zones of for ex. hydraulic conductivity and then calibrate the model either manually (less and less often done...) or automatically using PEST....

Recent advancements in PEST introduced highly parameterized inversion with regularization as improved version of calibration

What becomes obvious is that it is not enough to stop modeling workflow with calibration and running prediction - next step, uncertainty analysis is necessary to quantify the uncertainty and based on that improve decision making.

This webinar will give quick introduction to uncertainty analysis with Groundwater Vistas and PEST.

Determination of causes of geothermal well clogging – case study from SE Europe, microbial aspect

In the recent literature on water well clogging (or plugging) it was found that 80% of causes of well deterioration was caused by microbes.

During the summer of 2017. in SE Europe geothermal well experienced problems with incrustation. Although the temperature of water in well is about 56 C it was suspected that origin was biological.

Microbiological testing was done to prove that, and the results were positive. Next round of sampling is scheduled in about 3 weeks, after well rehabilitation which will possible confirm lower bacteria number and good effectiveness of water well rehabilitation.
