Hydraulic engineering in the social-ecological delta: understanding the interplay between social, ecological, and technological systems in the Dutch delta by means of “delta trajectories.” Ecology and Society
van Staveren, Martijn F.; Environmental Policy Group, Wageningen University; martijn.vanstaveren@wur.nl; van Tatenhove, Jan P. M.; Environmental Policy Group, Wageningen University; jan.vantatenhove@wur.nl.
Several of the world's largest deltas have recently been conceptualized as social-ecological delta systems. Although such conceptualizations are valuable in emphasizing complex interaction between social actors and ecological processes in deltas, they do not go into specific dynamics that surround technological developments in the hydraulic domain. By drawing from concepts originating in socio-technical systems research, we stress the importance of technology, particularly the domain of hydraulic engineering, in shaping a delta’s future. Based on two geographically distinct cases of flood management infrastructure in the Dutch delta, we demonstrate the influence of existing hydraulic works, in mutual interaction with social responses and...

Вертикальное распределение моллюсков Mytilus Galloprovincialis Lam. и Mytilaster lineatus Gmel. на каменной наброске гидротехнического сооружения IBSS Repository
Соловьёва, О. В..
The number and size of mussels Mitilus Galloprovincialis Lam. and Mytilaster Lineatus Gmel. on the riprap of a hydraulic structure (southern pier of Sevastopol bay) was analyzed. It is shown that at this riprap, the distribution of mussels over depth is more determined by abundance of mytilidae larva in the water column, and less – by hydrodynamic effects.
Tipo: Book Section Palavras-chave: Mussels; Mytilidae; Hydrotechnical buildings; Hydraulic engineering.

Assessment of the ecological functionality of anthropogenically created habitats in the impoundment of the hydropower plant Freudenau (Vienna, Austria) with bi- and multivariate statistical analyses Rev. Bras. Zool.
Tarkus,Martin; Volkmann,Christian; Drexler,Silke-Silvia; Waidbacher,Herwig; Straif,Michael.
The construction of the hydropower plant Freudenau was accompanied by the introduction of new structures and habitats. This study processes and evaluates the ecological fish data for the periods 1999/2000 and 2003/2004. The area was subdivided into five sections and 19 habitats (stream kilometer 1914.50 to 1994.60). Bi- and multivariate analyses were inducted with SPSS© (SPSS 2007). The CPUE values show that most fish remain in the Transition Zone and in the Head of Reservoir. The cluster analyses of the individual habitats show that these can be characterized primarily by abiotic factors. There was a strong statistical relationship between the individual habitats and the Danube mainstream. We conclude that fish have access to the habitats and that there...
