“…This is because many rivers have been multiple-channel rivers in the past, but they were changed to narrow, straightened rivers by human activities [2,4,[48][49][50]. However, this study is different from previous studies.…”

“…The plots have more extensive distribution on the nMDS diagram in the multiple-channel sections than in the single-channel for the four fish species. In the Czarny Dunajec River and the Polish Carpathians, Wyżga et al (2012) [4] also used the nMDS to determine the differences between multiple-and single-channel sections. However, they used the average and CV of each environmental factor to analyze the data.…”

“…Flow velocity, water depth and substrate are generally measured as environmental factors in order to explore relationships between aquatic organisms and habitat [1][2][3][4]. One reason for this is that these environmental factors can be directly and easily measured, and another reason is that they can be connected with some hydraulic parameters which are used to characterize physical habitat conditions [4].…”

After Typhoon Morakot, dredging engineering was conducted while taking the safety of humans and structures into consideration, but partial stream reaches were formed in the multiple-channel sections in Cishan Stream because of anthropogenic and natural influences. This study mainly explores the distribution of each fish species in both the multiple-and single-channel sections in the Cishan Stream. Parts of the environments did not exhibit significant differences according to a one-way ANOVA comparing the multiple-and single-channel sections, but certain areas of the multiple-channel sections had more diverse habitats. Each fish species was widely distributed by non-metric multidimensional scaling in the multiple-channel sections as compared to those in the single-channel sections. In addition, according to the principal component analysis, each fish species has a preferred environment, and all of them have a wide choice of habitat environments in the multiple-channel sections. Finally, the existence of multiple-channel sections could significantly affect the existence of the fish species under consideration in this study. However, no environmental factors were found to have an influence on fish species in the single-channel sections, with the exception of Rhinogobius nantaiensis. The results show that providing multiple-channel sections in dredging activities could improve fish habitat environments.

“…A similar pattern of hydromorphological quality was found with the RHQ method for the Czarny Dunajec River, in which channelized cross-sections differed by three quality classes from cross-sections in the unmanaged reach with a multithread, vertically stable channel and by two classes from those in the unmanaged reach with a single-thread, deeply incised channel (Wy_ zga et al 2009(Wy_ zga et al , 2010b. Also in this river, the spectacular disparity in hydromorphological quality scores between different types of cross-sections was reflected in marked differences in the richness of riverine communities: fish (Wy_ zga et al 2009) and benthic macroinvertebrates (Wy_ zga et al 2012a).…”

Planning and implementation of effective restoration projects require appropriate assessment of a river's hydromorphological status. Two European standards on hydromorphological assessment of rivers and hydromorphological assessment methods used in Poland are reviewed in the context of their applicability for river restoration purposes. River Hydromorphological Quality assessment method is presented with a case study of the Biała River, Polish Carpathians, where this assessment was used as basis for a restoration project aimed to establish an erodible river corridor. The results of the assessment revealed significant differences in hydromorphological quality between unmanaged and channelized river crosssections, indicating channel regulation as a major cause of the hydromorphological degradation of the Biała and confirming the choice of the erodible river corridor as an appropriate method of its restoration. The assessment indicated hydromorphological features of the river that were severely modified within the channelized reaches and which are likely to improve the most with the removal of bank protection and allowing free channel migration.

River restoration is one of the most prominent areas of applied water-resources science. From an initial focus on enhancing fish habitat or river appearance, primarily through structural modification of channel form, restoration has expanded to incorporate a wide variety of management activities designed to enhance river process and form. Restoration is conducted on headwater streams, large lowland rivers, and entire river networks in urban, agricultural, and less intensively human-altered environments. We critically examine how contemporary practitioners approach river restoration and challenges for implementing restoration, which include clearly identified objectives, holistic understanding of rivers as ecosystems, and the role of restoration as a social process. We also examine challenges for scientific understanding in river restoration. These include: how physical complexity supports biogeochemical function, stream metabolism, and stream ecosystem productivity; characterizing response curves of different river components; understanding sediment dynamics; and increasing appreciation of the importance of incorporating climate change considerations and resiliency into restoration planning. Finally, we examine changes in river restoration within the past decade, such as increasing use of stream mitigation banking; development of new tools and technologies; different types of process-based restoration; growing recognition of the importance of biological-physical feedbacks in rivers; increasing expectations of water quality improvements from restoration; and more effective communication between practitioners and river scientists.
