Researcher from CNRS Visits IKG for Academic Exchange

On August 9, 2018, Dr. WangXiaoguang, researcher from the Institute of Hydrogeology under French NationalScientific Research Center (Centre national de la recherche scientifique, CNRS)and director of French Karst Hydrogeological Research Association, visited theInstitute of Karst Geology (IKG), China Geological Survey, the Ministry ofNatural Resources (MNR) in Guilin, China for academic exchange.

In the morning, Dr. Wang Xiaoguang,accompanied by Prof. Jiang Guanghui with IKG, visited Zengpiyan NationalArchaeological Site Park and Guilin Yaji Experimental Site (field research baseunder MNR). During the visit, Prof. Jiang introduced the progress of karsthydro-geological research in Zengpiyan and Yaji. They also held discussions onthe new methods and technologies regarding karst hydrogeology and karstology,and proposed the potential areas for future cooperation.

In the afternoon, Dr. Wangdelivered an oral presentation titled “Research progress on HydraulicTomography and its application in fissure and karst aquifers”, and “Water flowstructure in the early stage of karst fissure evolution”. In his speech, Dr.Wang presented the characteristics of Hydraulic Tomography, and the progress ofhis research team on Hydraulic Tomography and inversed hydro-geologicalparameters in karst cavern system. He highlighted the improved algorithm of theinverse model, as well as the process of developing the structure of karstcavern system with infiltration coefficient and water storage rate. Accordingto him, the heterogeneous, random calculus model in karst development has alsoachieved good results. He also discussed the possibility of using geophysicaland tracing experiments to validate the model in the study on porous mediumstructure.

Dr. Wang went on by proposing theprospect of studying karst medium with Hydraulic Tomography. In the future, theresearchers need to better understand the formation mechanism of individualgrikes; and study the formation mechanism of karst in the network systemconsisting of faults, fissures and joints with site-based hydro-chemicalobservation. He also discussed the relevant issues with other participants. Dr.Wang’s presentation provided good references for the researchers of IKG toconduct quantitative study and construct water models on karst.
