The diversity of rivers is not only reflected in the different types of soil through which they flow, but this diversity also depends on the changes in seasons and the differences between wet and dry years. The Drava River is a Central European river and one of the most important tributaries of the Danube. Under natural conditions, the transport of sediment in the Drava River is balanced, which means that in a certain area the amount of sediment carried away is replaced by the same amount from the upstream parts of the basin. Flowing through Croatia, the Drava River was dammed three times upstream of the mouth of the Mura River, while before entering Croatia it was dammed as many as 20 times. The construction of hydroaccumulation lakes, as part of hydropower facilities, changes the natural flow regime, causing significant hydrological and morphological changes at dam sites, as well as upstream and downstream of dams. The construction of dams on rivers reduces the number of plant and animal species by changing local habitat conditions. The construction of hydroelectric power plants leads to the canalization of certain parts of the watercourse, thus changing the erosion-sedimentation processes in the riverbed. A river in its natural state with all its elements is the best defense against seasonal floods. The construction of hydropower facilities changes the hydrological regime, that is, large fluctu-ations occur in the flow values in certain parts of the Drava River, which has an impact on the floodplains downstream and on the plant species characteristic of that type of habitat. Most of the plant species that are adapted to flood habitat conditions would lose most of the soil that is suitable for settlement with the construction of the reservoir. © 2022, University of Zagreb, Faculty of Mining, Geology and Petroleum Engineering.

Analiza rudnih ležišta i svojstava ruda može doprinjeti razumijevanju prirodnih mehanizama koji uvjetuju način eksploatacije i uporabu ruda u prošlosti. Međutim, ubikacija ležišta je izazovna zbog mogućnosti degradacije, potpunoga iskorištavanja te inhibicije obnove ili razvoja ležišta, prvenstveno uzrokovanih ljudskom aktivnošću i utjecajem na okoliš. U suvremenome krajoliku Podravine najviši potencijal za razvoj ležišta i jedino, djelomično razoreno ležište, ustanovljeno je na položaju Kalinovac – Hrastova greda 1 – 3. Na osnovi njegove analize izveden je model mehanizma formiranja, fizionomije i položaja ležišta u Podravini te je povedena rasprava o metodama eksploatacije kao i potencijanim prostorima pojave ležišta u odnosu na položaje arheoloških lokaliteta s tragovima proizvodnje željeza. U svrhu analize tehnološke iskoristivosti ruda sličnih svojstava iz arheološkoga konteksta, provedeno je eksperimentalno taljenje kalinovačke rude. Na osnovi rezultata objašnjavaju se čimbenici koji su mogli onemogućiti proizvodnju spužvastoga željeza.

However, the details of mobilization of mixed-texture bed materials at low flows, increasingly common due to climate change, are still unclear. The 161-km-long Hungarian alluvial reach of the Drava River, downstream of sections where flow characteristics have been heavily modified by human interference, was investigated in 2019. A monitoring campaign at cross-sections, on average 5.55 km apart, was launched to study channel morphology, bedload entrainment dynamics with regard to texture. For the survey, a sonar, an ADCP and a Helley–Smith bedload sampler mounted on a double-hull vessel was used. Our research pointed out an abrupt fining between river kms (hereafter: rkm) 175 and 170 (distance from the mouth), probably due to reduced armouring. The d60 fraction was found to be finer than in 2003 and 2012 for the upstream stations of Botovo and Bélavár, and showed a good correspondence with the records of the Barcs and Drávaszabolcs stations. Temporal fining and higher entrainment rate are due to (a) changing climate of the catchment, that is, diminishing flow between the monitoring dates (2003, 2012 and 2019); (b) reduced armouring, (c) variability of cross-sectional position of sampling points and (d) the different mesh size of the bedload samplers employed. Calculations of shear velocity, Reynolds and Shields numbers indicate more dynamic sediment motion than observed by previous studies. Our reach-scale results may be relevant for the alluvial sections of other alpine and subalpine, partially channelized rivers of similar size, flow dynamics and mixed bedload.}, keywords = {Hydromorphology; Drava River; armouring; bedload entrainment; bedload texture; regulated river}, year = {2021}, eissn = {1535-1467}, pages = {699-711}, orcid-numbers = {Pirkhoffer, Ervin/0000-0003-2917-3290; Halmai, Ákos/0000-0001-5722-8119; Ficsor, Johanna/0000-0001-9439-516X; Lóczy, Dénes/0000-0002-2542-6775; Liptay, Zoltán Árpád/0000-0001-8984-9366; Czigány, Szabolcs/0000-0002-9158-3162} } @article{MTMT:32557309, title = {Follow the Rivers?.

One of the main questions is how to interpret the differences and similarities between the two sites.
