Repeated invitation for holding the "OpenSource GIS course" in the frame of the IWRM course of the UFZ

In the frame of the - perhaps last - course on Integrated Water Ressorce Management of the UFZ (in collaboration with the DAAD and several other institutions) the OpenSource GIS course was held in Dessau. The 20 participants from Vietnam, Indonesia, Kazachstan, Mongolia, Iran and Jordan were very interested in the "third edition" of this course on Sep 9-11, 2014. The OpenSource tools have reached a high scientific standard by now and therefore they are preferred in these countries with minor financial ressources. But also the extendability and the possibilities for combinations and data exchange are important arguments for the drstaically rising application.

Presentations at the FH-DGG conference in Bayreuth

The dept. hydrogeology and Environmental Geology of the Martin-Luther-University took part at this conference with totally 6 presentations. The width of the presented research topics ranged from field tools like the high resolution data logger for water pressure (interval 10 ms, resolution 10 µm) up to the geological models and the 3d variogrametry.

Participation at IT² and transHal

The department hydrogeology and Environmental Geology of the Martin-Luther-University participated with presentations at the days IT² and transHal. These meetings between industry, small companies, universities and administration/authorities are important to see, what is the focus of the work around the own pot.

Geostatistical and GIS topics in the C++ programming course

The C++ programming course on geostatistics and GIS saw participants from the Helmholtz Centre for Environmental Research (UFZ) as well from the Martin-Luther-University (study courses Applied Geosciences and Management of Natural Ressources). Especially the development of geostatistical algorithms and their graphical user interfaces were focussed in this three days course.

New Ph.D student for geological modelling

Since February 2014 Lars Schimpf is on boarrd of the working group Hydrogeology and Environmental Geology. His focus will be the dynamical geological modelling with the development of the necessary tools. His regional focus is the town of Halle, so that in the near future also this 3d model will be improved step by step.

New software tools developed

The new modules of MO2GEO bring along much new functionality and allow for new methods of scientific analysis. The explorer got a new outfit and the data formats for input and export have been improved. For the field module not only additional standards have been implemented but also cross section generation is made possible and the connection to the postgreSQL database management system improves data availability and safety.

Additionally an interpolation tool for a simple smoothing has been developed that can be used optionally in MO2GEO.

Presentations of the Hydrogeology and Environmental Geology at the IAMG Conference Sep. 2-6, 2013 in Madrid

At the annual conference of the International Association for mathematical Geosciences (IAMG) at the University of Madrid the  Hydrogeology and Environmental Geology of the Martin Luther University Halle had three oral presentations and two poster presentations. Lars Schimpf presented on September 2 the FieldModule of MO2GEO which was a result of his Diploma mapping thesis. Also on September 2 Ronny Laehne and Wolfgang Gossel showed their poster presentation about time series analysis. The around 200 participants of the conference had daily about 45 minutes for a look at the 15-20 posters and a talk with the authors. The tight hall of the conference contributed to intensive contacts and exchange of ideas. Thomas Horschig, an MSc student, presented his work about the geologically bound optimization of the groundwater monitoring network in Halle on September 4. Compared to other groundwater monitoring networks the fault systems with upconing saltwater stood in front of this investigation and not any contaminated sites or aerially widespread groundwater stresses. On September 6 Wolfgang Gossel presented the interpolation method L-IDW that he developed together with Michael Falkenhagen (geography) and Thomas Chudy (agriculture). The tool HydroFaBer was topic of a poster made by Ronny Laehne and Dorothee Altenstein. The tool is used for the calculation of depth to groundwater in hardrock areas with very low density of groundwater observation wells.

The posters and oral presentations of the working group were very well recognized by the conference participants and new applications of the methods were confirmed.

In the frame of the conference a visit to the modern Town Hall of Madrid in the park Retiro was included as well as a conference dinner in the Casino of Madrid. Based on the good resonance on the presented topics we look forward expectantly to the conference at our partner University Jawarhalal Nehru University (JNU) in New Delhi next year.

Presentation and research journey to Andhra Pradesh

Prof. Dr. N. J. Raju from the partner university of the Martin Luther University, the Jawarhalal Nehru University organized a journey of em. Prof. Dr. G. Bachmann (Regional and Historical Geology)  and PD Dr. W. Gossel (Hydrogeology and Environmental Geology) to Universities in Andhra Pradesh. The contacts to the Universities GITAM University (Visakhapatnam, Andhra Pradesh), Andhra University (Visakhapatnam, Andhra Pradesh), and Sri Venkateswara University (Tirupati, Andhra Pradesh) were used for presentations about saltwater/freshwater interface modeling in Northeastern Africa, Mexico and Halle and for excursions in the vicinity of the towns. In Visakhapatnam mainly saltwater intrusions in coastal sediments were focused. In Tirupati three different topics were discussed and the according sites were visited. In the riverbed of the Swarnamukhi River subsurface dams were built for a better water management in the dry 2-3 months. In the open pit mine Mangampeta Mine (Barite) the water management and the hydrochemistry were focused and for the Pulikat Lake the saltwater/freshwater questions were central. The collaboration and exchange with the Indian colleagues was very seminal and will be helpful for joint project proposals.

Short course about OpenSource GIS in the frame of the EU-TEMPUS project in Egypt

The use of OpenSource GIS is interesting for students for three reasons: They can use the software for free, they can learn from the source code and they can add their own methods to the tools. Therefore the application of these tools increases in various contexts and also our partners in the TEMPUS project were very interested in this topic. The course schedule was adapted to the needs of students coming from civil engineering. Dr. Wolfgang Gossel held this more raster data oriented intensive course at Ain Shams University from November 18-20, 2012. The difficult political conditions did not play a role in this course.

GIS course with international participants

In this year the International GIS Training Course on 3d Hydrogeology and Environmental Geology was held in July. The 20 participants came from Oman, Mexico, Czech Republic, the next house on the campus (the Environmental Research Centre, UFZ) and of course from the University. Main topic were the 3d GIS tools, developed in the working group, called HyVis and InVis. HyVis is a 3d structural modelling tool whereas InVis is a 3d interpolation tool. Both tools are based on ESRI software and freely available (with manuals) on the homepage of the working group. Also a viewer system for simple 3d models was introduced (MO2GEO viewer) that was presented already at the CeBIT 2011. Dr. Gossel was supported this year by Ronny Lähne.

EU-TEMPUS project continued in 2011

This year two parts of the EU TEMPUS project were carried out by the Martin Luther University: One course held by Dr. Wolfgang Gossel with two parts in Egypt (Cairo and Assiut) and another course with two parts in Halle, also held by Dr. Wolfgang Gossel. The 2 days short courses March 23-24 in Cairo (REGWA company) focussed on hydrochemistry and the 4 days short course in Assiut March 26-29 on geological and hydrogeological modelling. Due to the “arab spring” time and the beginning semester in Halle an originally planned one week excursion to the Egyptian Oases had to be cancelled.Three participants from Ain Shams University in Cairojoined the groundwater flow and transport modelling courses September 10-21 at the Martin Luther University. The courses were interrupte by trips to Dresden and Leipzig.

Project presentations at the conferences of the International Association for Mathematical Geology, International Mine Water Association and ModelCaRe

The conference of the International Association for Mathematical Geology in Salzburg (Austria) was dedicated in this year to all kinds of geological modelling: Geological structures as well as hydrogeological flow and transport models, reservoir models and models in engineering geology and palaeontology – the computer has turned to one of the most important tools of a geoscientist. The working goup was therefore invited to present 4 posters as there were the model applications (geological model of Halle, Julia Rienäcker) and the development of tools and methods (Ronny Lähne and Dr. Wolfgang Gossel). An unexpected chance was given to Dr. Wolfgang Gossel to present his research about the interfaces of hydrogeological modelling systems in an oral presentation.At the conference of the International Mine Water Association in Aachen a joint MSc project of the working groups of Hydrogeology and Environmental Geology and the Mineralogy was presented. Felix Yobo Amoako got high recognition for his poster about the investigation of tailings of gold mining in Ghana and he had many opportunities for long talks about his research results. Dr. Wolfgang Gossel got the possibility to present two posters of the working group with the topics Halle model and MO2GEO development.

Hydrogeology and Environmental Geology present their models of worldwide project areas at the CeBIT

Hydrogeology and Environmental Ggeology present their models of worldwide project areas at the CeBIT
The Institute for Geosciences, Department Hydrogeology and Environmental Geology, developed methods for the generation and visualization of geological and hydrogeological models together with the Institute for Computer Sciences. The 3d models are applied in several national and international projects e.g. the modelling of the mexican peninsula Yucatan. Focus of the joint research of the Martin Luther University Halle, the Universidad Autonoma de Merida (Mexico) and the University Aachen (RWTH Aachen) is the behaviour of the saltwater-freshwater interface during the last 150,000 years. With the computer simulations it is possible to calculate groundwater models of areas that are up to eight times larger than Germany. “A special focus is the concept of efficient modelling in these projects to save resources in workload and power” explains Dr. Wolfgang Gossel from the Institute for Geosciences. To meet the special demands of the software and the distinct projects, the hardware has to be fitted according to the project. Some of the models and especially the modelling techniques are presented at the CeBIT in Hannover (March 1 to 5, 2011).

Geologists at the CeBIT: Geological exhibits in 3d

In the collections of the Institute for Geosciences of the Martin Luther University in Halle (Germany) some rare samples of rocks and fossils can be found, that are needed and used regularly by other scientists worldwide for their research. Normally these samples were sent by mail and this took a long time and was dangerous especially for fragile samples. Sometimes the samples even got lost. On the other hand a lot of new samples have to be catalogued by now. To overcome these problems and to make the samples worlwide available for a lot of research purposes the geoscientists of the Martin Luther University in Halle develop methods to visualize the samples in 3d. The most important samples are scanned with a laser scanning system which has been enhanced and adapted to this purpose and to get high resolution and measurable pictures. The results are published in 3d-pdf to reduce the cost of visualization.
