Bank infiltration in area of Jordán meander on Orlice river
Drmota, Adam ; Hrkal, Zbyněk (advisor) ; Slavík, Martin (referee)
This thesis deals with the study of the Jordán meander on the Orlice River, where the watercourse has undergone extensive revitalization in recent years, which after several decades returned the watercourse to its original riverbed. In connection with the revitalization of the watercourse, an increase in the level of groundwater in the surrounding quaternary aquifer was expected. In this case we can call it artificial bank infiltration. In order to confirm this assumption, hydrogeological boreholes HV1 to HV4 were placed at the site, and they were used for groundwater level monitoring since year 2018. The results of the monitoring document the positive impact of the revitalization on the level of groundwater in the surrounding river alluviums. Furthermore, it was found that boreholes on different banks of the Orlice River react to flow rates in the river and revitalization measures, quite differently. Differences can also be caused by orders of magnitude different hydraulic parameters on both banks, which have been verified using field pumping tests. Keywords: Bank infiltration, monitoring, pumping tests, revitalization
