“…water improvement is increasing worldwide (Nakamura et al, 2006(Nakamura et al, , 2009Palmer and Bernhardt, 2006;Wohl et al, 2005). Assessing the outcome of these projects is essential for adaptive management, evaluation of project efficiency, optimization of future programs, and gaining public acceptance (Woolsey et al, 2007).…”

Abstract.Floodplains have been intensively altered in industrialized countries, but are now increasingly being restored. It is therefore important to assess the effect of these restoration projects on the aquatic and terrestrial components of ecosystems. However, despite being functionally crucial components of terrestrial ecosystems, soils are generally overlooked in floodplain restoration assessments.We studied the spatio-temporal heterogeneity of soil morphology in a restored (riverbed widening) river reach along the River Thur (Switzerland) using three criteria (soil diversity, dynamism and typicality) and their associated indicators. We hypothesized that these criteria would correctly discriminate the post-restoration changes in soil morphology, and that these changes correspond to patterns of vascular plant diversity.Soil diversity and dynamism increased 5 yr after the restoration, but some typical soils of braided rivers were still missing. Soil typicality and dynamism were correlated to vegetation changes. These results suggest a limited success of the project, in agreement with evaluations carried out at the same site using other, more resource-demanding, methods (e.g., soil fauna, fish diversity, ecosystem functioning).Soil morphology provides structural and functional information on floodplain ecosystems. The spatio-temporal heterogeneity of soil morphology represents a cost-efficient ecological indicator that could easily be integrated into rapid assessment protocols of floodplain and river restoration projects.The follow-up assessment after several major floods (≥ HQ20) should take place to allow for testing the longerterm validity of our conclusion for the River Thur site. More generally, it would be useful to apply the soil morphology indicator approach in different settings to test its broader applicability.

“…The preservation of aquatic resources for ecosystem and human health and well-being is a paramount concern worldwide and it has become evident that approaches to managing aquatic resources must be undertaken within the context of ecosystem dynamics in order that their exploitation for human uses remains sustainable [10]. If aquatic resources are not properly managed and aquatic ecosystems deteriorate, then human health and well-being may be compromised.…”

The present study highlight the toxicity levels of different heavy metals in aquatic environment of one of the most polluted river of Mumbai-the Mithi River. Although the river has attracted tremendous attention after 26/7 flood in Mumbai, the pollution level of the river has remained neglected issue. The present study was performed for two assessment years 2009-10 and 2010-11 at three different sampling stations namely Airport, CST Kalina and BKC Taximen's Colony along the flow of Mithi River. The results of present investigation indicates that the concentration levels of most of the heavy metals like Al, As, Cd, Cr, Hg, Ni, Pb, Sr and Mn obtained during the assessment year 2010-11 was higher than that obtained during 2009-10 by the factor of 1.4 to 5.7 µg/L. The environmental impact of these toxic heavy metals is discussed. The results point out the need of rational planning of pollution control strategies, so as to keep check on release of toxic heavy metals in the river. It is expected that the present study will be useful for rational planning of pollution control strategies and their prioritisation; to evaluate effectiveness of pollution control measures already is existence and to assess the nature and extent of pollution control needed.

“…Muller et al [49] hypothesized that humanity-for its own sake and benefit-is likely to continue degrading rivers by introducing newly built infrastructure than to restore the rivers' environmental features. However, along with increases in sustainable growth and outstanding recent advances in ecological engineering, with more than 1000 dams removed in the US [44] more than 1 billion USD spent on river restoration in the US [50] and more than 23,000 river stretches restored in Japan [51] the awareness of the need for a high-quality environment will also rise [52,53], so we believe this negative scenario will not come to pass.…”

Abstract:The purpose of the present research was to analyze the available data on river restoration projects in Europe. As the framework of our study, we conducted a structured international survey. We asked selected entities and experts from among those responsible for river restoration in European countries about the details and costs of European Union river restoration projects. We examined 119 river restoration projects that were implemented in Europe between 1989 and 2016; during the collection of data, some of the projects were still ongoing. Based upon the collected data we observed that the number of river restoration projects has been increasing since 1989, which expresses society's growing interest in improving the quality of aquatic environments. We revealed that 56% of these European river restoration projects have been implemented by dedicated entities and stakeholders, not as part of any structured, larger-scale river restoration policy. This indicates that most European countries do not have integrated plans for river restoration. Our analysis showed that 52% of the projects analyzed have been designed and implemented without the participation of local stakeholders. It also showed that the budgets for river restoration projects did not differ significantly across various time horizons from 1989 to 2016. In our study, the average cost of restoring 1 ha of an European river was 310,000 euros (EUR). Considering these projects' permanent assets and including their amortization, we calculated the average unit price of a river restoration's value in terms of ecosystem meta-service to be 7757 EUR·ha −1 ·year −1 .
