Pesticide trends in a tailwater recovery system in the Mississippi Delta

open access: yesAgrosystems, Geosciences & Environment, 2022
Tailwater recovery (TWR) systems are an important best management practice (BMP) used to address both water quality and quantity issues in the Mississippi Delta region.

Sedimentation in an artificial lake ‐ lake matahina, bay of plenty [PDF]

open access: yes, 1981
Lake Matahina, an 8 km long hydroelectric storage reservoir, is a small (2.5 km2), 50 m deep, warm monomictic, gorge‐type lake whose internal circulation is controlled by the inflowing Rangitaiki River which drains a greywacke and acid volcanic catchment.

Rehabilitation of an Incised Stream Using Plant Materials: the Dominance of Geomorphic Processes

open access: yesEcology and Society, 2008
The restoration of potentially species-rich stream ecosystems in physically unstable environments is challenging, and few attempts have been evaluated scientifically.

Two-phase modeling of batch sedimentation [PDF]

open access: yes, 1999
A two-phase model for the simulation of sedimentation processes is presented. The model solves the continuity and momentum equations for the pure-clear liquid and the sludge phases, and it is verified against a well-known benchmark problem, for which ...

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 ...

Modeling hydrography and marine sedimentation in the Cariaco Basin since the Last Glacial Maximum [PDF]

open access: yes, 2009
The Cariaco Basin has shallow connections with the Caribbean Sea, and these are further reduced at times of lower sea level, such as at the Last Glacial Maximum (LGM).

Predicting ephemeral gully erosion with RUSLER and EphGEE [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
Ephemeral gully erosion is not included in predictions made with the Revised Universal Soil Loss Equation, version 2 (RUSLE2). A new distributed application called RUSLER (RUSLE2-Raster) predicts distributed soil loss and its output can be linked with ...

A novel global hydrodynamic analysis of the molecular flexibility of the dietary fibre polysaccharide konjac glucomannan [PDF]

open access: yes, 2009
Konjac glucomannans have been widely considered in health food products although their hydrodynamic properties have been poorly understood. The weight-average molecular weight (Mw); sedimentation coefficient (s020,w) and intrinsic viscosities ([η]) have

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 ...

Hydrodynamic of flood in bedrock bend reach: laboratory experiment

open access: yesShui kexue jinzhan, 2022
Low-slope bedrock meandering rivers widely exist in areas controlled by geological structures (the bed slope is less than 5‰). Flood has a great influence on riverbed sedimentation and erosion in bedrock meandering rivers, however, we have a poor ...
