How agriculture software for nutrient optimization can help to protect groundwater?

According to a new report by the European Environment Agency (EEA), only 40% of the continent’s water bodies are compliant with the agency’s environmental standards set by the European directive on water, which was adopted in 2000. The directive offers a framework for the evaluation, management and improvement of water resources throughout Europe.

In this webinar you will have integrated approach, unique to Environmental Modeling Solutions experts for mitigation of nitrate problem in groundwater.

Case Study of Monitored Natural Attenuation Remediation of Xylene in Groundwater

In this presentation Dragan Kaludjerovic will show you his PhD thesis from 2008 which is related to remediation of contaminated groundwater from 45 tonne spill of xylene at railway station. Now, in 2019, the question arises, what can be done better?

First, in webinar, the case study will be described and then "new" technique pilot point (highly parameterized inversion with regularization) application in groundwater flow and transport calibration will be shown. Uncertainty analysis using Null Space Monte Carlo method with PEST is logical next step.

Second, new software that replaced RT3D will be mentioned shortly (MT3D USGS) and multilevel sampling in groundwater will be covered.

Micro gravimetry in geological and hydrogeological modeling

Gravimetry is very often used geophysical method in geological and hydrogeological investigations. In this webinar I am going to show you how this investigation can be implemented to get better conceptual model using software for 3D geology modeling GeoModeller.

Also, GeoModeller can export geological model to MODFLOW or FEflow software for hydrogeological modeling.

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.

Calibration is not enough - making better groundwater models 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.
