“…For example, historical aerial photographs have been used to quantify the long-term geomorphic response of river channels to dam construction and water abstraction (e.g., Gurnell et. al 1994;Tiegs and Pohl 2005). Another option involves palaeo techniques, where hindcasting of past conditions and diversity is achieved by examining organisms preserved in lake sediment profiles (e.g.…”

SummaryBiological monitoring has a long history in freshwaters, where much of the pioneering work in this field was developed over a hundred years ago -but few of the traditional monitoring tools provide the global perspective on biodiversity loss and its consequences for ecosystem functioning that are now needed. Rather than forcing existing monitoring paradigms to respond to questions they were never originally designed to address, we need to take a step back and assess the prospects for novel approaches that could be developed and adopted in the future. To resolve some of the issues with indicators currently used to inform policymakers, we highlight new biological monitoring tools that are being used, or could be developed in the near future, which (1) consider less-studied taxonomic groups; (2) are standardised across regions to allow global comparisons, and (3) measure change over multiple time points. The new tools we suggest make use of some of the key technological and logistical advances seen in recent years -including remote sensing, molecular tools, and local-to-global citizen science networks. We recommend that these new indicators should be considered in future assessments of freshwater ecosystem health and contribute to the evidence base for global to regional (and national) assessments of biodiversity and ecosystem services: for example, within the emerging framework of the Intergovernmental Platform on Biodiversity and Ecosystem Services.

“…The active channel width was mapped as the union of low-flow channels and bars not covered with vegetation (Gurnell, 1997;Gaeuman et al, 2003;Gendaszek et al, 2012;Leviandier et al, 2012;Ziliani and Surian, 2012;Rollet et al, 2013;Toone et al, 2014;Liro, 2015) excluding islands (Tiegs and Pohl, 2005;Swanson et al, 2011;Nelson et al, 2013). The channel width was calculated by dividing the channel area by its length for each 50-m-long segment.…”

“…Eco-hydromorphic variation has been studied over a wide range of spatial and temporal extents } the latter often in the course of long-term monitoring, such as flow gauging (Sheffer et al, 2003), retrospective aerial photograph/map analyses of geomorphology (Tiegs and Pohl, 2005) and annual river bird surveys (Carter, 1989). Long-term monitoring can provide invaluable information about the behaviour of river systems, as can palaeohydrological investigations that extend the study of river variability over hundreds or thousands of years, or even into longer geological and evolutionary time-scales (Sear and Arnell, 2006).…”

ABSTRACT1. The assessment of links between ecology and physical habitat has become a major issue in river research and management. Key drivers include concerns about the conservation implications of human modifications (e.g. abstraction, climate change) and the explicit need to understand the ecological importance of hydromorphology as prescribed by the EU's Water Framework Directive. Efforts are focusing on the need to develop 'ecohydromorphology' at the interface between ecology, hydrology and fluvial geomorphology. Here, the scope of this emerging field is defined, some research and development issues are suggested, and a path for development is sketched out.2. In the short term, major research priorities are to use existing literature or data better to identify patterns among organisms, ecological functions and river hydromorphological character. Another early priority is to identify model systems or organisms to act as research foci. In the medium term, the investigation of patternprocesses linkages, spatial structuring, scaling relationships and system dynamics will advance mechanistic understanding. The effects of climate change, abstraction and river regulation, eco-hydromorphic resistance/ resilience, and responses to environmental disturbances are likely to be management priorities. Large-scale catchment projects, in both rural and urban locations, should be promoted to concentrate collaborative efforts, to attract financial support and to raise the profile of eco-hydromorphology.3. Eco-hydromorphological expertise is currently fragmented across the main contributory disciplines (ecology, hydrology, geomorphology, flood risk management, civil engineering), potentially restricting research and development. This is paradoxical given the shared vision across these fields for effective river management based on good science with social impact. A range of approaches is advocated to build sufficient, integrated capacity that will deliver science of real management value over the coming decades.
