Channel incision is a widespread phenomenon throughout the dry interior Columbia River basin and other semi‐arid regions of the world, which degrades stream habitat by fundamentally altering natural ecological, geomorphological and hydrological processes. We examined the extent of localized aggradation behind beaver dams on an incised stream in the interior Columbia River basin to assess the potential for using beaver, Castor canadensis, dams to restore such channels, and the effect of the… 

The Geomorphic and Hydrologic Impact of Beaver Dams on Headwater Streams in Northeastern Connecticut and Implications for River Restoration

Of the many types of barriers to water flow, beaver dams are among the smallest, typically lasting less than a decade and rarely exceeding 1.5 meters in height. They are also among the most frequent

Sediment storage and shallow groundwater response to beaver dam analogues in the Colorado Front Range, USA

Enthusiasm for using beaver dam analogues (BDAs) to restore incised channels and riparian corridors has been increasing. BDAs are expected to create a similar channel response to natural beaver dams

Impacts of beaver dams on hydrologic and temperature regimes in a mountain stream

Beaver dams affect hydrologic processes, channel complexity, and stream temperature in part by inundating riparian areas, influencing groundwater–surface water interactions, and changing fluvial

Human Alterations of Rivers

People have been altering the environment since prehistory. Archeological records and the stratigraphy of valley bottoms suggest that prehistoric alteration of native upland vegetation for grazing

The beaver meadow complex revisited – the role of beavers in post‐glacial floodplain development

We evaluate the validity of the beaver‐meadow complex hypothesis, used to explain the deposition of extensive fine sediment in broad, low‐gradient valleys. Previous work establishes that beaver

Reintroduced Beavers Rapidly Influence the Storage and Biogeochemistry of Sediments in Headwater Streams (Methow River, Washington)

Abstract North American beavers (Castor canadensis) were targeted within North American headwater landscapes by European loggers and fur traders in the 19th century, reducing beaver populations to

Managed Flood Effects on Beaver Pond Habitat in a Desert Riverine Ecosystem, Bill Williams River, Arizona USA

The ecological effects of beaver in warm-desert streams are poorly documented, but potentially significant. For example, stream water and sediment budgets may be affected by increased evaporative

Alteration of stream temperature by natural and artificial beaver dams

TLDR
Observations reveal several mechanisms by which beaver dam development may influence stream temperature regimes; including longitudinal buffering of diel summer temperature extrema at the reach scale due to increased surface water storage, and creation of cool—water channel scale temperature refugia through enhanced groundwater—surface water connectivity.

Impacts of beaver dams on channel hydraulics and substrate characteristics in a mountain stream

Beaver dams have significant impacts on the hydrology, temperature, biogeochemical processes, and geomorphology of streams and riparian areas. They have also been used as a viable tool in restoring
