The development of Vrhnika was strongly affected by the construction of the so called Austrian Southern Railway in the 1840s. Its construction features as one of the displays at the Ljubljanica River ...Exhibition, 2016
From a hydrological point of view, active caves are a series of connected conduits which drain water through an aquifer. Water tends to choose the easiest way through the system but different ...geological and morphological barriers act as flow restrictions. The number and characteristics of restrictions depends on the particular speleogenetic environment, which is a function of geological, geomorphological, climatological and hydrological settings. Such a variety and heterogeneity of underground systems has presented a challenge for human understanding for many centuries. Access to many underground passages, theoretical knowledge and recent methods (modeling, water pressure-resistant dataloggers, precise sensors etc.) give us the opportunity to get better insight into the hydrodynamic aspect of caves. In our work we tried to approach underground hydrodynamics from both theoretical and practical points of view. We present some theoretical background of open surface and pressurized flow in underground rivers and present results of some possible scenarios. Moreover, two case studies from the Ljubljanica river basin are presented in more detail: the cave system between Planinsko polje and Ljubljansko barje, and the cave system between Bloško polje and Cerkniško polje. The approach and methodology in each case is somewhat different, as the aims were different at the beginning of exploration. However, they both deal with temporal and spatial hydrodynamics of underground waters. In the case of Bloško polje-Cerkniško polje system we also explain the feedback loop between hydrodynamics and Holocene speleogenesis.
The history and heritage of the town of Vrhnika is mostly presented by reproductions of archival materials and videos, yet also features a number of artefacts that used to belong to the former ...industrial establishments from the region, 2016
In main springs and swallowholes of the Ljubljanica River Basin the monitoring of heavy metals was established at the beginning of 2005 with the intention to study the solute transport in the water ...body and to analyse the risk of contamination with heavy metals. The results of the first monitoring phase are presented–elements that indicate the load of environment due to industry, traffic,agriculture and urbanisation:Al,As,Cd,Cl,Cr,Cu,Mn in Pb. The results point out that the vulnerability of karst aquifers depends on aquifer hydrodynamic conditions, infiltration conditions and development of a karst drainage system. Furthermore, they indicated the local and regional geochemical and hydrogeological characteristics and enable to evidence the main processes and effects that impact on environmental changes.
Že skoraj razstavljen stari litoželezni Hradeckega (Čevljarski) most. Sestavne dele so izdelali v livarni Dvor pri Žužemberku in ga postavili 1867. Veljal je za enega najzgodnejših te vrste v ...srednji Evropi. Leta 1931 so ga postavili na Poljanski nasip. Posneto s Hribarjevega nabrežja.
