We propose a statistical model to analyse the impact of tracer sample size and tracer loss on the representativeness of samples in tracer studies in gravel‐bed rivers. Abstract Tagged particles (painted, with inserted magnets, RFID labelled) used as tracers have often been deployed in field experiments focused on tracking the displacement of river ...

Using 16 flume experiments and 2D modeling, we show that large‐wood flow resistance is not a fixed property of wood porosity but varies systematically with flow condition, blockage and most strongly sediment‐shaped bed topography. The drag coefficient and Manning's n are interchangeable, but calibration is essential where scour occurs.

Modelling Flood‐Induced Riparian Vegetation Disturbance and Hydro‐Morphodynamic Feedbacks
A process‐based framework links flood‐induced vegetation disturbance to hydro‐morphodynamic feedback by separating mechanical failure from postfailure outcomes, explaining spatial distribution patterns of washout, burial and localized embankment erosion during the 2019 Chikuma River flood.

Knickpoint Morphology in Homogenous Substrates Controlled by Sediment Cover and Base‐Level Fall Rate
Knickpoints can form spontaneously under constant forcing, without external perturbations. Flume experiments reveal three distinct morphologies, controlled by the balance between base‐level fall rate and sediment cover. A new conceptual model shows how erosion, sediment armouring and plunge pool dynamics govern knickpoint morphology, challenging ...

Rapid Hydraulic Modelling in Post‐Wildfire Channels Using a Tiered Framework
A three‐tier hydraulic modelling framework enables rapid, safe calibration of post‐wildfire channel models using remote sensing and limited field data. Tested on two contrasting burned Colorado watersheds, discharge and salt tracer velocity measurements alone captured most of the achievable model accuracy, with detailed bathymetric survey adding little

ABSTRACT Background and Aims Bovine anaplasmosis is an intracellular tick‐borne, non‐contagious disease caused by gram‐negative bacteria of the family Anaplasmataceae and order Rickettsia. Anaplasma phagocytophilum is the etiological agent for human granulocytic anaplasmosis associated with severe health implications in parts of Europe and the USA and ...

Short‐Term Effects on Rill Erosion and Flow Resistance in a Wood‐Biochar Amended Soil
This investigation evaluates the short‐term effects of wood‐biochar addition, with two different concentrations (BC = 3 and 5%) to soil on rill erosion and flow resistance. The results demonstrated that, in the short term, the addition of BC = 3% is effective in reducing soil erosion phenomena as compared to the control condition, while adding BC = 5 ...
