Incorporating climate change into restoration decisions
Incorporating climate change into conservation and restoration decisions is increasingly important for natural resource managers and restoration practitioners to effectively address the underlying drivers of ecosystem change. Small dam removal is an example of a restoration tool that may offer multiple socioeconomic and ecological benefits in streams, including promoting climate resilience. With the pace of dam removals increasing, practitioners …
Networks, Coalitions and the Contestation of Dam Removal Across Political and Institutional Scales in France and New England (Usa)
Conflicts over dam removal have attracted substantial scholarly attention over the past years, although this research has generally focused on evaluating local-scale conflicts. Far less is known about the role of institutional frameworks in shaping conflicts at regional and national scales. We complement and extend this discussion by highlighting the politics of scale in dam removal conflicts, specifically by a comparison of cases in northwest of…
Peopling the Environmental State
Dam removal in the United States is an increasingly attractive option for advocates of river restoration. We argue that dam removal in New England (United States) is a useful lens for examining state actors’ capabilities to govern environmental processes. Our analytical framework builds off and integrates strategic-relational approaches (SRAs) to state power and those approaches more concerned with “peopling” the state through state agents’ every…
Geomorphic Responses to Extreme Rainfall, Catastrophic Flooding, and Dam Failures across an Urban to Rural Landscape
The extreme rainfall of October 2015 in South Carolina generated numerous dam failures and spawned the flood of record at most U.S. Geological Survey stream gauges. Detailed field sampling and systematic image analysis are used to document the immediate and sustained geomorphic adjustments at four failed dams within the urbanized Gills Creek watershed. That urban focus is augmented with a similar analysis at five failed dams in more rural setting…
River restoration by dam removal
The prolonged history of industrialization, flood control, and hydropower production has led to the construction of 80,000 dams across the U.S. generating significant hydrologic, ecological, and social adjustments. With the increased ecological attention on re-establishing riverine connectivity, dam removal is becoming an important part of large-scale river restoration nationally, especially in New England, due to its early European settlement an…

Quantifying flooding regime in floodplain forests to guide river restoration
Determining the flooding regime needed to support distinctive floodplain forests is essential for effective river conservation under the ubiquitous human alteration of river flows characteristic of the Anthropocene Era. At over 100 sites throughout the Connecticut River basin, the largest river system in New England, we characterized species composition, valley and channel morphology, and hydrologic regime to define conditions promoting distinct …

Channel Adjustments to Dams in the Connecticut River Basin
Through an analysis of at-a-station channel and reach-averaged fluvial properties, we document the stream channel, riparian, and hydraulic adjustments associated with six dams in the Upper Connecticut River basin. For the reach-scale geomorphic analysis, we measured channel planform properties of five tributaries and one mainstem section using geographic information systems of available aerial photographs that pre- and postdate the dams. For the …
Floodplain Development, El Niño, and Cultural Consequences in a Hyperarid Andean Environment
Using field-mapping, remote-sensing (ASTER, aerial photography), and GIS/GPS, we identified and analyzed reach-scale geomorphic responses to contemporary floods along a 20-km valley length in hyperarid southern Peru. We combined these data with alluvial stratigraphy of remnant terrace patches recording late Holocene aggradation and incision. In this manner we ascertained how climate change, especially the occurrence of the El Niño–Southern Oscill…
Applied geomorphology
Thinking across the divide
This paper reports on a meeting which was held at the RGS/IBG annual conference in London in September 2003, where we aimed to investigate and debate some of the ways in which human and physical geography could (and should?) reopen a dialogue. This conference session was timely for three reasons. First, whilst human geography has a long tradition of engaging in philosophical discussion, physical geographers have been rather more reluctant to exam…
Historical Land-Cover Changes and Hydrogeomorphic Adjustment in a Small Georgia Watershed
This study utilizes hydrologic modeling (HEC-1) for discrete episodes of land use in a Georgia watershed to portray the hydrologic adjustments that occur during a period of intensive land clearing and subsequent revegetation. It then compares these hydrologic shifts to field-based geomorphic adjustments such as gullying and valley aggradation. The Turner Creek watershed, settled in the mid-1830s, experienced a period of rapid land clearing with i…
Soil Erosion in a Coastal River Basin
Variations in Slope Components during Large Magnitude Floods, Wisconsin
Errors are associated with the substitution of map and water surface slopes for energy gradients in hydraulic estimation procedures. Many paleodischarge reconstruction techniques assume one-to-one correspondence between water surface slope and slope measured from a topographic map. The assumption that map slope or water surface slope, however, can be directly substituted for energy slope, involves unknown degrees of error. This research shows tha…
Historical Floodplain Sedimentation in the Galena River Basin, Wisconsin and Illinois
Post-settlement alteration of the natural land cover accelerated floodplain sedimentation in the Galena River basin in Wisconsin and Illinois. Twenty-three stream channels and valley cross sections originally surveyed by the Soil Conservation Service c. 1940 were resurveyed in 1979. A comparison of the two surveys shows that bankfull cross-sectional area has generally decreased since 1940, especially in the upper and middle portions of the basin …
