Abstract Beaver dam analogues (BDAs) are a cost‐effective stream restoration approach that leverages the recognized environmental benefits of natural beaver dams on channel stability and local hydrology. Although known to exert considerable influence hydrologic conditions system by mediating geomorphic processes, nutrient cycling, groundwater–surface water interactions, impacts beaver‐derived methods exchange poorly characterized. To address this deficit, we monitored hyporheic fluxes...
Abstract Ice formation is generally considered to exclude many particles and most solutes thus be relatively pure compared ambient waters. Because river ice forms by a combination of thermal mechanical processes, some level sediment entrainment in the column likely, though reports are limited. We observed high sporadic levels silt sand Kuskokwim Tanana rivers (Alaska, United States) during routine field studies. These observations led us make more comprehensive survey Yukon several their...
Abstract Natural beaver ponds help connect the stream to floodplain, maintain late summer low flows and reduce peak flow during high events by offering temporary surface water (SW) storage. When beavers are extirpated from landscape, degradation often ensues. This study assesses impact of dam analogues (BDA) as a restoration technique levels enhance stream‐floodplain interactions on seasonal basis in Red Canyon Creek, Lander, WY. BDAs increased SW groundwater (GW) levels, favoured occurrence...
Abstract Avulsions change river courses and transport water sediment to new channels impacting infrastructure, floodplain evolution, ecosystems. Abrupt avulsion events (occurring over days weeks) are potentially catastrophic society thus receive more attention than slow avulsions, which develop decades centuries can be challenging identify. Here, we examine gradual channel changes of the Peace‐Athabasca River Delta (PAD), Canada using in situ measurements 37 years Landsat satellite imagery....
Abstract Beaver dam analogs (BDAs) are a stream restoration technique that is rapidly gaining popularity in the western United States. These low‐cost, stream‐spanning structures, designed after natural beaver dams, being installed to confer ecologic, hydrologic, and geomorphic benefits of dams streams often too degraded provide suitable habitat. BDAs intended slow streamflow, reduce erosive power stream, promote aggradation, making them attractive tools incised channels. Despite increasing...
Abstract River systems in the mountain western USA have been shaped by presence of beavers for millennia. However, extirpated from landscape many places, leading to excessive stream incision and streambank erosion. One common strategy mitigate this issue is deploy beaver dam analogue (BDAs) as a restoration technique. Although BDAs are intended reduce erosion incision, few studies directly document impact on channel geomorphology. This study, therefore, assesses how complex five along 150 m...
Through the Sediment, Ice, & Learning on Tanana (SILT) project, a team of university scientists engaged two middle school student groups in testing innovative environmental research technologies to measure sediment flowing underneath river ice. The culturally responsive, place-based pilot program tests these as strategy increase students' science interest and self-efficacy. Over series three workshops, 39 students built deployed low-cost turbidity sensors ice designed model payload...
Abstract Open-source designs for turbidity and depth sensors are becoming increasingly capable available, but the knowledge required to construct them limits their use compared expensive, commercial sensors. Here, we present an open-source optical backscatter water pressure sensor that can be ordered almost fully assembled, requires no coding deploy, costs approximately $50 USD. We share three examples of these sensors’ ability facilitate new research. First, observed complex changes in...
