“…Other channel changes associated with incision included thalweg relocation (Meador & Layher, 1998), decreased floodplain connectivity (Kiss et al, 2018;Wy_ zga et al, 2009;González, Masip, & Tabacchi, 2016), a reduction in connectivity between river and groundwater (González et al, 2016), and changes to groundwater levels (Bayram et al 2014). Lower groundwater levels were linked to inhibiting the establishment of riparian vegetation on river banks impacted by sand mining in the lower Eygues River, France (Kondolf, Piégay, & Landon, 2007) and were suggested as hindering efforts to restore impacted rivers.…”

Sand mining (used here as a generic term that includes mining of any riverine aggregates regardless of particle size) is a global activity that is receiving increasing media attention due to perceived negative environmental and social impacts. As calls grow for stronger regulation of mining, there is a need to understand the scientific evidence to support effective management. This paper summarizes the results of a structured literature review addressing the question, “What evidence is there of impacts of sand mining on ecosystem structure, process, and biodiversity in rivers, floodplains, and estuaries?” The review found that most investigations have focused on temperate rivers where sand mining occurred historically but has now ceased. Channel incision was the most common physical impact identified; other physical responses, including habitat disturbance, alteration of riparian zones, and changes to downstream sediment transport, were highly variable and dependant on river characteristics. Ecosystem attributes affected included macroinvertebrate drift, fish movements, species abundance and community structures, and food web dynamics. Studies often inferred impacts on populations, but supporting data were scarce. Limited evidence suggests that rivers can sustain extraction if volumes are within the natural sediment load variability. Significantly, the countries and rivers for which there is science‐based evidence related to sand mining are not those where extensive sand mining is currently reported. The lack of scientific and systematic studies of sand mining in these countries prevents accurate quantification of mined volumes or the type, extent, and magnitude of any impacts. Additional research into how sand mining is affecting ecosystem services, impacting biodiversity and particularly threatened species, and how mining impacts interact with other activities or threats is urgently required.

“…As they all developed on the low-lying surfaces, their aggradation is very intensive, primarily because small but more frequent flood-waves could accumulate sediment here, secondary because these (nearbankfull) floods transport the highest amount of sediment. In contrary, on the higher floodplain sections, the older natural levees could evolve just during exceptionally large floods (Kiss et al, 2018). C-type natural levees are almost evenly distributed along the studied reach of the Maros, as almost the whole reach is intensively narrowing, though near to the confluence (units 25-31) the members of the C-type are missing, as here the channel slightly widened.…”

“…The members of class C are the youngest, as they evolved on the new, low-lying floodplain surfaces formed by channel narrowing (Kiss et al, 2017(Kiss et al, , 2018. Though these forms are the narrowest (width mean : 46 m), they are high (height mean : 1.6 m), therefore they have the steepest slopes (slope mean : 0.0428; Tab.…”

“…Very intensive accumulation processes characterise the floodplain of the Maros River (Kiss et al, 2011), which could be explained by its considerab le sediment discharge. However, the processes of vertical and horizontal aggradation is limited by recent channel narrowing and incision Kiss, Nagy, & Balogh, 2017;Kiss, Balogh, Fiala, & Sipos, 2018). The spatial and temporal changes in accumulation are known from sedimentary analysis (Kiss et al, 2011), but the various floodplain forms created by the intensive accumulation were unknown due to the missing spatial data.…”

The floodplain forms of lowland rivers act as fluvial archives, as their morphology, material and spatial characteristics refer to the hydromorphological changes of the river and (dis)connectivity of the alluvial system. The aims of the research are (1) to identify natural levees, crevasses, and point-bars on the Hungarian floodplain section of the Maros River, (2) to measure their morphometric parameters, and (3) to analyse their spatial and temporal variations in connection with various human impacts. Six genetic types of natural levees and pointbar systems developed as the result of various human impacts, thus the development of the forms terminated or became laterally limited.

“…Currently, the Adige features a straight to sinuous pattern and an average channel width of 58-82 m (Scorpio et al, 2018). Similarly to other large rivers in the Alps and in Central Europe (Adami, Bertoldi, & Zolezzi, 2016;Eschbach et al, 2018;Hohensinner, Habersack, Jungwirth, & Zauner, 2004;Kiss, Balogh, Fiala, & Sipos, 2018;Zawiejska & Wyzga, 2010), the Adige River was subjected to massive channelization works during the nineteenth century, to ensure flood protection, to reclaim agricultural land, and to facilitate navigation and terrestrial transportation. The Adige boasts the availability of a huge number of accurate large scale historical maps (Mastronunzio & Dai Prà, 2016a, 2016bScorpio et al, 2018)besides earlier paintings and subsequent aerial photoscovering most of its valley bottom, thereby offering a robust opportunity to identify its morphodynamic corridors through sequential information covering a long time period.…”

A 1:50,000-scale geomorphological map of the Adige/Etsch River valley bottom (NE Italy) is presented. The study area is 115 km long, and it extends between the villages of Merano/ Meran and Calliano, including also the terminal segments of 9 major tributaries of the Adige River. Presently, the Adige shows a sinuous to straight morphology owing to massive channelization occurred during the nineteenth century. Fluvial geomorphological features have been mapped through a detailed-scale comparative multi-temporal analysis carried out on several historical maps dating since the eighteenth century, previous thematic maps, geological maps of the Italian 'CARG' project, orthophotos (2011) and highresolution DEMs. The map shows the active river channel, dating to 1803-1805 (before channelization), to 1856-1861 (during channelization) and under present conditions, as well as several paleochannels dating up to the thirteenth century. The analysis led to define the corridor of historical channel changes, a fundamental tool for river management purposes.
