Rivers, regulation and restoration: land use history of floodplains in a peri-urban landscape in Luxembourg, 1777 - 2000

This paper discusses the historical changes to and the uses of floodplain landscapes in Luxembourg from 1770-2000 as a case study of a region with a rural past and a peri-urban present. Based on the historical landscape analysis approach, the study comprises historical evidence of written, cartographic and oral sources collected at a regional (Gutland) and a local (Syr Valley) level. The floodplains investigated were old cultural landscapes, shaped by agriculture, livestock husbandry, river regulation measures, land improvement, milling, navigation, mining and fisheries. Landscape change has been characterised by different periods of intensity, however it was not until the last century that these changes had a large-scale impact, inducing a complete loss of several ecological and socio-economic functions. A historical perspective of local landscape conditions and land use change is needed to maintain landscape identity in a contemporary peri-urban environment, and to base planning and restoration activities on reliable data.

Subject and purpose of work: This article identifies changes in the economic use of the river valley area of the Krzna, which occurred as a consequence of the regulation of its bed from the Klukówka estuary to the estuary of the Krzna to the Bug.

Materials and methods: The analysis was carried out on the basis of cartographic maps and aerial photographs, as well as statistical analyses for the period 1931-2015.

Results: The study confirmed the changes in the economic use of the valley of the Krzna River for the agricultural exploitation of the area and increasing crop yields. The biggest changes encompassed wetlands and swamps, mainly in favour of grasslands, whose area increased by 566%, to 2475.7 ha.

Conclusions: The regulatory work carried out resulted in an increase in arable land, forests and areas for development, as well as in the reduction of water surface area from 251.94 ha in 1931 to 57.28 ha in 2015.

The paper presents a reconstruction and an analysis of the Vistula river bed changes in the 19th and 20th centuries, performed on the basis of topographic maps. The analysis took into account both natural (floods, changes in rock-debris supply) and anthropogenic (e.g., river regulation, construction of water reservoirs) causes, which resulted in significant changes of the morphology of the Vistula river bed. To estimate the river bed changes the author used such parameters as: the length of the banks and changes of their location, the width of the river bed, and the surface of the river bed forms and their share in the river bed surface area.


This article presents an analysis of cartographic materials of the 19th and 20th centuries in terms of changes in the surface water network of the Gardno-Łeba Lowland. The obtained results confirmed that the natural water network was slightly transformed in the first half of the 19th century and considerably increased in the 20th century as a result of agricultural drainage system, especially drainage of wetlands, and river regulations. As a consequence, a hydrographic system with a forced water circulation has developed, that is quite different from the natural. On the one hand, it has become the reason for reversing the proportion in which the groundwater resources have been depleted, along with an increase in the surface water network density, and on the other hand it has caused a change in land use.


Channels of Czadeczka and Krężelka rivers (Beskidzie Śląski Mts) are at present subjected to regulation because of which these rivers have lost their natural character, partially still preserved. The reasons for the river regulation have been analysed. Using archival maps, the buildings erection time has been analysed on valley floors, in the immediate vicinity of river channels for the period 1790-2012. Next, the distribution of existing buildings has been compared with hydraulic structures in the channels developed in order to regulate the Czadeczka and the Krężelka reaches, such as: concrete and stone embankments reinforcing the channel banks, check dams on channel bottoms. Results indicate a strong correlation between the number of buildings on valley floors in the 20th century and channel regulation. The mechanism of destroying rare, preserved natural river reaches is based on irrational permission allowing construction of buildings in areas threatened by floods and lateral erosion of rivers. Consequently, the inhabitants, in fear of floods and erosion of land or house foundations, seek river regulation that gives them a false sense of security. Natural river reaches are destroyed though efficient protection against floods and lateral erosion is still not provided and the range of possible losses increases even more due to continued building erection.


Huchen, Hucho hucho (L.), also known as Danube salmon, is an iconic, endemic species inhabiting the Danube basin of Central Europe. Historically, the Danube huchen inhabited a significant portion of the Danube drainage basin stretching to the Iron Gate and the majority of large and medium-sized tributaries. Larger populations in the natural zoogeographical distribution of Danube huchen were once found in Austria, Bavaria, the former Yugoslavia, Slovakia, and western Ukraine. Currently, the species is severely fragmented within the Danube drainage, where most populations exclusively depend on stocking and natural reproduction is very limited due to habitat alterations and flow regime changes. In the Czech Republic and Poland, Danube huchen occurrence is the result of introducing the species to several rivers in the Baltic Sea and North Sea drainage basins. Danube huchen is a threatened species throughout is range of occurrence, and, according to IUCN criteria, it is classified as endangered (EN). Habitat degradation is the most serious negative factor impacting huchen populations. Dam construction, pollution, and river regulation have led to loss and degradation of spawning sites. Detailed research on population abundance and structure is greatly needed to help identify the populations which are most threatened and to help to develop the best protection systems.
