Shallow water habitat management influences soil CO2 efflux from agricultural fields in the Lower Mississippi River Basin (LMRB), USA

open access: yesAgrosystems, Geosciences & Environment, 2023
Temporary winter flooding is a common practice for enhancing wildlife habitat in the Lower Mississippi River Basin (LMRB) and other migratory waterfowl flyways in North America. This practice also facilitates nutrient retention and reuse of rainwater‐ or

Erosion depth of sand from an immobile gravel bed [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
This study was conducted to improve prediction of the depth of erosion of sand (D50 = 0.3–0.9 mm) from immobile gravel (D50 = 36.1 mm) under steady uniform flows with bed shear stresses from 0.1 to 0.9 of that required to entrain the gravel.

Evaluating sediment transport capacity relationships for use in ephemeral gully erosion models [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
On cropland, ephemeral gully erosion in the USA may contribute up to 40% of the sediment delivered to the edge of the field. Well-tested, physically- and process-based tools for field and watershed scale prediction of gully erosion are lacking due to the

Stability analysis of riverbanks with a dual structure under water–root–soil coupling

open access: yesWater Science and Technology, 2023
The collapse mechanism of dual-structure vegetation riverbanks at different water levels is unclear. A method for calculating the critical collapse width of a dual-structure vegetation bank under different failure modes that consider the variations in ...

Size-sorting dust grains in the surface layers of protoplanetary disks [PDF]

open access: yes, 2008
Aims: We wish to investigate what the effect of dust sedimentation is on the observed 10 mum feature of protoplanetary disks and how this may affect the interpretation of the observations.

Quantifying the changes of soil surface microroughness due to rainfall impact on a smooth surface [PDF]

open access: yesNonlinear Processes in Geophysics, 2017
This study examines the rainfall-induced change in soil microroughness of a bare smooth soil surface in an agricultural field. The majority of soil microroughness studies have focused on surface roughness on the order of ∼ 5–50 mm and ...

Distributed soil loss estimation system including ephemeral gully development and tillage erosion [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
A new modelling system is being developed to provide spatially-distributed runoff and soil erosion predictions for conservation planning that integrates the 2D grid-based variant of the Revised Universal Soil Loss Equation, version 2 model (RUSLER), the ...
