Waterborne GPR survey for estimating bottom-sediment variability: A survey on the Po River, Turin, Italy [PDF]
, 2009 We conducted an integrated geophysical survey on a stretch of the river Po in order to check the GPR ability to discriminate the variability of riverbed sediments through an analysis of the bottom reflection amplitudes.

Strategic assessment of bridge susceptibility to scour
Reliability Engineering & System SafetyScour-induced failures of bridges pose a global challenge, leading to significant economic and service losses. Compounded by infrequent inspections and inadequate consideration of hydro-geological factors in current scour risk assessments, this issue is particularly pressing in the context of climate change and associated hazards.

Geomorphic Effects and Habitat Impacts of Large Wood at Restoration Sites in New England
River Research and Applications, EarlyView.ABSTRACT Large wood (used interchangeably with the term “instream wood”), which refers to trees, logs and other wood within a channel, is beneficial to river ecosystems and is being used more frequently as a component of river restoration projects. We identified metrics to evaluate the effectiveness of large wood to promote ecological and geomorphic ...

Analisis Susunan Tirai Optimal Sebagai Proteksi Pada Pilar Jembatan Dari Gerusan Lokal [PDF]
, 2008 Local scour frequently occurs in the downstream of energy muffler or around the bridge pillars. The bridge pillar function decreases due to the scour of soil material around it.

Using Trail Cameras to Monitor Culvert Connectivity in Wadeable Streams
River Research and Applications, EarlyView.ABSTRACT Anthropogenic barriers in aquatic habitats have led to fragmentation and decreased fish diversity worldwide. Road crossing barriers such as culverts are a significant source of fragmentation and can impede aquatic organism passage (AOP). Many large extent efforts to inventory road crossing barriers and prioritize restoration efforts do not ...

Influence of junction angle on three-dimensional flow structure and bed morphology at confluent meander bends during different hydrological conditions [PDF]
, 2014 © 2014 John Wiley & Sons, Ltd. Recent field and modeling investigations have examined the fluvial dynamics of confluent meander bends where a straight tributary channel enters a meandering river at the apex of a bend with a 90° junction angle.

River Research and Applications, EarlyView.ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...
