“…Macrophyte species composition in floodplain areas is indicative of the degree of hydrological dynamics, and restoration measures are, thus, expected to result in alterations in the macrophyte composition (Reckendorfer et al 2005). Both a controlled water supply and a reconnection will increase the potential habitats for emerged and submerged macrophytes by increasing the total surface water area (Table 25.3).…”

“…With increasing Danube water levels, larger areas are inundated, including also terrestrial habitats. The connectivity of the various floodplain water bodies ranges from 140 days per year in the downstream parts of the main side arm adjacent to the inflow to less than 2 days per year in isolated ponds in the upstream parts of the Lower Lobau (Reckendorfer et al 2006).…”

“…It provides habitat for a diverse fauna and flora and was designated as a national park in 1996 (Reckendorfer et al 2005). Within this stretch, the urban Lobau floodplain is located, which is a 2020 ha large floodplain area in the most western part of the national park right at the eastern border of the City of Vienna (Fig.…”

Since elements of nature and society interact to determine the integrity and trajectory of these systems, they are referred to hereafter as socialecological systems (SESs). This introduction opens the door to these topics in four steps. It begins by explaining why a book dedicated to river management and science is needed at this point. In the second part, it outlines the history of some of the major developments that challenge the integrity of SESs worldwide. In the third part, it describes several of the principal tools used to study as well as manage SES. Tools to measure the degree of degradation of an SES include indicators of biological integrity, ecosystem health, and resilience. Tools to assess and manage the trajectory of an SES include the DPSIR and adaptive management. The introduction closes by outlining the structure of the book through the progression of its chapters. Justification of BookRivers are among the most threatened ecosystems of the world. For more than a centur...

“…Along the Danube River (Alluvial Zone National Park, Austria), hydrological connectivity was the main determinant that explained the distribution of aquatic organisms across a river-floodplain gradient ( Fig. 5; Tockner et al, 1998;Reckendorfer et al, 2005). Most species exhibited a distinct preference for a specific degree of connectivity.…”

Ecology of Braided Rivers

Braided gravel-bed rivers are widespread in temperate piedmont and mountain-valley areas. In their pristine state, braided rivers are characterized by a shifting mosaic of channels, ponds, bars, and islands, since both flow and flood pulses create a diversity of habitats with fast turnover rates. Large wood has a major role in determining the geomorphology and ecological functioning of these rivers. Braided river habitats are colonized by a diverse fauna and flora adapted to their dynamic nature, including a significant proportion of highly endangered species. Animals exhibit high mobility, short and asynchronic life cycles, and ethological and phenological plasticity. Braided gravelbed rivers also offer various categories of refugia such as shore areas, hypogeic and hyporheic habitats that are pivotal for maintaining diversity in the face of frequent disturbances. Today, however, most gravel-bed rivers bear little resemblance to their highly dynamic natural state due to anthropogenic modifications, and most braided rivers have been converted into incised single-thread channels. Gravel bars and vegetated islands are among the most endangered landscape elements worldwide. They are very sensitive to channelization, gravel extraction, and flow regulation. Therefore, more than for most other ecosystems, restoring braided rivers and their landscape elements means restoring their underlying hydrogeomorphological dynamics.

“…Recently, natural and human-modified spatiotemporal habitat dynamics have also been analysed to develop adequate river/floodplain restoration programs. These include the Cyclical Floodplain Rejuvenation concept for the Rhine River in the Netherlands (Wolfert, 2001;Baptist et al, 2004) or the Integrated River Engineering Project for the Danube River in the Austrian Alluvial Zone National Park (Reckendorfer et al, 2005).…”

Modern, holistic concepts dealing with river/floodplain ecology recognize the key role of hydromorphological turnover processes for the development of distinct habitat patterns. Such patterns, in turn, are a vital basis for the extraordinary biodiversity of riverine systems. Natural braided/anabranched river systems in particular are characterised by high turnover rates; in the mid-term, however, they are thought to stay in dynamic equilibrium (shifting-mosaic steady-state) as long as the physical framework conditions remain unchanged. This study analyses both the historical composition and the spatio-temporal development of riverine habitats associated with an anabranched section of the Austrian Danube River. A habitat age model was used to analyse the age structure of the different habitat types. The results for the period 1812-1821 prior to channelization indicate that terrestrialization and habitat ageing were almost balanced with habitat regeneration and rejuvenation. Even though intensive morphological changes occurred, the Danube here largely persisted in dynamic equilibrium. The first channelization measures between 1821 and 1838, when 21% of the main channel banks were embanked, slightly promoted habitat regeneration. From 1859 onwards (80% embanked) until 1925, the natural habitat life time cycle was disrupted and the regenerating processes almost ceased. Altogether, human interferences led to a river landscape in a morphologically static state governed by significant terrestrialization (habitat succession) and habitat ageing. Without natural disturbances or, alternatively, targeted habitat management strategies, such an ecosystem soon lacks morphologically young habitats and adequate site conditions for a river/floodplain type-specific biocoenosis.
