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

Geosciences, 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.

The role of vegetation, drying, and rewetting on water and sediment phosphorus concentrations in an experimental ditch channel experiment

Agrosystems, Geosciences & Environment
Intermittent drying and rewetting of agricultural drainage ditch networks along with vegetation presence play a significant role in phosphorus (P) fate and transport to the receiving water bodies.

Discharge coefficient of vertical sluice gates with broad crested weir under free-submerged orifice flows using best subset regression

Water Science and Technology
Accurate calculation of flow discharge for sluice gates is essential in irrigation, water supply, and structure safety. The measurement of discharge with the requirement of distinguishing flow regimes is not conducive to application.

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

Visnik 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.

Solitary wave-induced 2D seepage effects on sediment incipient motion

Applied Ocean Research
Solitary wave theory has been extensively applied to describe wave motions in very shallow water. Previous studies on sand movement induced by solitary waves have typically neglected the effects of seepage flow.

Effect of Standing Water on Formation of Fan‐Shaped Sedimentary Deposits at Hypanis Valles, Mars

Geophysical Research Letters, 2023
Fan‐shaped sedimentary deposits are key indicators of paleoclimate on Mars. The largest example, a multi‐lobed deposit (>1,000 km2) at the outlet of Hypanis Valles, may have formed either subaerially or at the edge of a water body.

Analytical Ultracentrifugation: Sedimentation Velocity and Sedimentation Equilibrium [PDF]

, 2008
Analytical ultracentrifugation (AUC) is a versatile and powerful method for the quantitative analysis of macromolecules in solution. AUC has broad applications for the study of biomacromolecules in a wide range of solvents and over a wide range of solute concentrations. Three optical systems are available for the analytical ultracentrifuge (absorbance,
