Sub‐annual spatiotemporal dynamics of sediment and organic matter storage in beaver ponds
Ponds higher up the beaver cascades showed increasing erosion of sediments following heavier rainfall events, whereas those further down showed increasing sediment accretion. Following periods with less intense rainfall all ponds showed net sediment accretion.

ABSTRACT Background Hospital‐acquired infections (HIAs) remain a major threat to patient and healthcare worker (HCW) safety globally, with higher burden in low‐resource settings. Despite moderate knowledge among HCWs in many low‐income contexts, actual adherence to infection prevention practices is often poor.

Consulta en la Biblioteca ETSI Industriales (8769) [EN] According to the Federal Highway Administration (FHWA) the number of bridges declared ¿scour critical¿ total more than 26,000 just in the U.S.A. Besides, in spite of the significant investment in bridge scour research, these bridges still fail due to scour.

Groundwater‐dependent native riparian ecosystems of the Gila River floodplain (a) near the upstream end of the valley in winter 2014 and (b) near the downstream valley end in summer 2018. Topographically complex floodplains create favourable conditions across the full breadth of the valley bottom for a diversity of native groundwater‐dependent ...

Using the most complete summary of 20 years of riparian plant water use studies in North American drylands to date, we examine broad patterns of plant water use by vegetation type and across climate gradients. Marshes, cottonwood‐willow stands and tamarisk use larger amounts of water than other communities, and all communities have higher water use in ...

ABSTRACT Stream fragmentation is a leading threat to freshwater fish diversity and is often caused by the installation of impassable culverts at road–stream crossings. In the United States alone, millions of culverts contribute to this fragmentation. Therefore, estimating culvert barrier impact on aquatic organism passage and prioritizing barriers for ...

Down-flow and horseshoe vortex characteristics of sediment embedded bridge piers [PDF]
The flow around bridge structures is a recent research topic, given the significance of bridges as basic engineering infrastructures. This study investigates the internal flow features around circular bridge piers by Particle Image Velocimetry applied ...
