The Role of Hydraulic Connectivity and Management on Soil Aggregate Size and Stability in the Clear Creek Watershed, Iowa

open access: yesGeosciences, 2018
The role of tillage practices on soil aggregate properties has been mainly addressed at the pedon scale (i.e., soilscape scale) by treating landscape elements as disconnected.

Characterization and evolution of the sediments of a Mediterranean coastal lagoon located next to a former mining area [PDF]

open access: yes, 2015
Coastal lagoons are ecosystems that are relatively enclosed water bodies under the influence of both the terrestrial and themarine environment, being vulnerable to human impacts.

A study of a quasilinear model of the particles of a suspension that are aggregated and settled in an inhomogeneous field

open access: yesVisnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika, 2020
The mathematical model of the sedimentation process of suspension particles is usually a quasilinear hyperbolic system of partial differential equations, supplemented by initial and boundary conditions.

Concentration Dependen Sedimentation of Collidal Rods

open access: yes, 2000
In the first part of this paper, an approximate theory is developed for the leading order concentration dependence of the sedimentation coefficient for rod-like colloids/polymers/macromolecules.

Contaminated Aquatic Sediments [PDF]

open access: yesWater Environment Research, 2007
A review of the literature published in 2014 relating to the assessment, evaluation and remediation of contaminated aquatic sediments is presented. The review is divided into the following sections: policy and guidance, methodology, distribution, fate and transport, bioavailability, bioaccumulation, risk, toxicity and remediation.

Shear-induced sedimentation in yield stress fluids [PDF]

open access: yes, 2012
Stability of coarse particles against gravity is an important issue in dense suspensions (fresh concrete, foodstuff, etc.). On the one hand, it is known that they are stable at rest when the interstitial paste has a high enough yield stress; on the other

Autogenic Sedimentation in Clastic Stratigraphy

open access: yes, 2017
Internally generated, or autogenic, terrestrial and marine sediment-transport dynamics can produce depositional patterns similar to those associated with climatic, tectonic, or sea level changes.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Effects of flood conditions on lake water quality in an agricultural watershed with multiple conservation practices

open access: yesAgrosystems, Geosciences & Environment
This study measured 17 surface water quality (WQ) parameters in a 731 ha Conservation Effects Assessment Project watershed, Beasley Lake, in Mississippi, under varying flooding conditions from 2008 to 2022.
