“…Sinuosity and braiding were defined in the literature to analyze river patterns, which are also referred to as river planforms [1,18]. The sinuosity and braiding of a river result from hydraulic factors and the topography of the drainage basin.…”

“…The data required for determining the river planform and for calculating the sinuosity and braiding values can be obtained using ground surveys, Global Navigation Satellite System (GNSS) measurements, maps, aerial photogrammetry, and remote sensing methods [1,18,[22][23][24]. However, remote sensing is generally an optimal method because it can be used to view the same area on different dates and to obtain measurements in different sections of the electromagnetic spectrum and is fast and economical [5,25,26].…”

“…The floodplain metrics largely correspond to the objectives of reconnecting floodplains or restoring channel meanders, whereas the in-channel metrics largely correspond to the remaining objectives of restoring incised channels, increasing structural complexity, or reducing sediment supply. Measure lengths of widest channel and side channels from aerial photography (Friend and Sinha, 1993) Node density or channel complexity index…”

“…By contrast, changes in the number or length of side-channels (sometimes referred to as braids) can be monitored using the braid-channel ratio and node density, both of which are easily measured from aerial photography. The braid-channel ratio is the length of all side channels (braids) divided by the length of the main channel (channel) (Lsc/Lmain; Friend and Sinha, 1993;Beechie and others, 2006). Node density is the total number of channel junctions within a specified channel length (such as nodes per km of channel; Luck and others, 2010) or a more complex metric such as the river complexity index, or channel sinuosity multiplied by node density (Brown, 2002).…”

ISSN 2331ISSN -1258 iii AbstractHabitat restoration efforts by the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) have shifted from the site scale (1-10 meters) to the reach scale (100-1,000 meters). This shift was in response to the growing scientific emphasis on process-based restoration and to support the 2007 Accords Agreement with the Bonneville Power Administration. With the increased size of restoration projects, the CTUIR and other agencies are in need of applicable monitoring methods for assessing large-scale changes in river and floodplain habitats following restoration. The goal of the Physical Habitat Monitoring Strategy is to outline methods that are useful for capturing reach-scale changes in surface and groundwater hydrology, geomorphology, hydrologic connectivity, and riparian vegetation at restoration projects. The Physical Habitat Monitoring Strategy aims to avoid duplication with existing regional effectiveness monitoring protocols by identifying complimentary reach-scale metrics and methods that may improve the ability of CTUIR and others to detect instream and riparian changes at large restoration projects.

A major deterrent to a full understanding of the ecological ramifications of river regulation at the catchment scale is a lack of fundamental knowledge of structural and functional attributes of morphologically intact river systems. For example, both the River Continuum and the Serial Discontinuity Concepts, in their original formulations, had the implicit assumption of a stable, single‐thread channel from headwaters to the sea. The Fiume Tagliamento traverses a course of 172 km from its headwaters in the Italian Alps to the Adriatic Sea. No high dams impede the river's passage as it flows through the characteristic sequence of constrained, braided, and meandering reaches. The Tagliamento, the only large morphologically intact Alpine river remaining in Europe, provides insight into the natural dynamics and complexity that must have characterized Alpine rivers in the pristine state. The Tagliamento has a flashy pluvio‐nival regime (mean Q=109 m3 s−1, with flood flows up to 4000 m3 s−1). Thousands of newly‐uprooted trees were strewn across the active bed and floodplain along the river's course following a major flood in the autumn of 1996. The active floodplain is up to 2 km wide and contains a riparian vegetation mosaic encompassing a range of successional stages. Up to 11 individual channels per cross section occur in the braided middle reaches. Islands are a prominent feature of the riverine landscape and island dynamics are postulated to play a key role in determining pattern and process across scales. Future studies will examine the roles of island dynamics and large woody debris in structuring biodiversity patterns of aquatic biota and successional trajectories of riparian vegetation. The high levels of spatiotemporal heterogeneity exhibited by the Fiume Tagliamento provide a valuable perspective for regulated river ecologists and those engaged in conservation and restoration.
