Sedimentation and Consolidation of cohesive and non-cohesive soils formed under turbulent flows
… and erosion of mixed soil material (cohesive and non-cohesive). Soil beds formed by sedimentation process of loose particles will be either show a segregated or homogeneous in structure, depending on the depositional environment. These sediments initially undergo self-weight …

Non-cohesive bank migration in meandering rivers and bank accretion in weakly braided rivers
… rivers whose banks consist wholly, or partly, of non-cohesive bed-material-sized alluvial deposits; such banks are known as composite banks when the near-surface layers consist of fine-grained deposits. The relevant forces and environmental conditions that must be taken into account to quantify …

Evolution of a non-cohesive granular bed subject to a succession of erosive turbidity currents
… was performed to study the evolution of a non-cohesive granular bed subject to a succession of erosive turbidity currents to evaluate the applicability of a proposed interface model that prescribes a relationship between the bed shear stress and the local bed elevation and local bed slope. …

Effect of self-stratification on channel flows and boundary layers: a study using direct numerical simulations
… have helped to differentiate the effect due to cohesive and non-cohesive sediment; but an inherent property of suspended sediment irrespective of being cohesive or non-cohesive is to evolve into a stable stratification, thereby suppressing turbulence in the flow. New insights into inherent …

Dynamics of particle clouds related to open-water sediment disposal
… capture (i.e., "trap") mechanisms, and various cohesive and non-cohesive particles. Particle sizes were scaled to real-world dimensions through the cloud number (Nc), defined as the ratio of the particle settling velocity to the characteristic cloud velocity. An "inverse" integral model was …

Sediment erosion and deposition within mangrove forests
… the erosion threshold and rate of natural cohesive sediment collected from a black mangrove habitat. Sediment cores with intact belowground and aboveground biomass were placed in a recirculating channel. Pneumatophores were removed from one side of each core. Each side of the core, with and …

Extrusion performance and physicochemical characterization of texturized native and chemically modified whey proteins in carbohydrate-containing systems
… bonds contributed to the formation of hard, non cohesive products, whereas hydrophobic interactions resulted in brittle, less cohesive extrudates. Free amino groups of whey proteins appeared to play an important role in texture formation. An increase in the negative charge of the protein …

Adjustment Experiences of African American Graduates of Historically Black Colleges or Universities Attending Graduate School at a Southern Predominantly White University
… frustration, lack of African American presence, non-cohesive African American community, racial microaggressions, prior acquaintances and resilience.

The context-specific roles of a bioturbating crab (Austrohelice crassa) on ecosystem functioning
… manipulation experiment was conducted in a non-cohesive sand and a cohesive muddy-sand to test the hypothesis that the functional plasticity of Austrohelice among sediment types would be reflected in measures of solute exchange; a proxy for ecosystem functioning. In both habitats, …

Estabilização de areia com cinza volante e cal; efeito do cimento como aditivo e de brita na mistura
… to enhance fly ash role the soil chosen was a non-cohesive one - a uniform dune sand - which is not quite suitable for stabilization with cement and not at all with lime. Stabilization effect results from cementation of sand grains by the product from pozzolanic reaction of lime with fly ash in …

Influence of riparian vegetation on near-bank flow structure and rates of erosion on a large meandering river
… of roughness along banks composed primarily of non-cohesive sediment vary as bank elevation increases and show a tendency for a dominant length scale of roughness, whereas banks composed of fine-grained silt and clay increase the resistance properties of the banks and promote uniform roughness …

An investigation of the structural capacity of the Alabama Department of Transportation’s standard prestressed precast concrete piles
… particularly uses them in the coastal regions in non-cohesive soils and where corrosion would be expected from salt or brackish water. ALDOT’s currently listed pile design capacities in their structural design manual (SDM) were found to be lower than those for similar PPCP pile sizes used in …

Do Muds Sort? Experimental Test of a Hypothesis Key to Understanding Marine Bottom Currents
… 'sortable silt' hypothesis and states that the non-cohesive, coarse silt in the 10 to 63 µm size range within a deposit can be used as a proxy for paleocurrent velocity. Slow deposition rates on contourites (2−10 cm/kyr) make it difficult to test this hypothesis in the field and few laboratory …

Characterization and Modeling of Deformable Soils for Tire Performance Simulations
… presents significant challenges because of its non-linear and complex behavior, which depends on multiple external and internal factors. This thesis focuses on developing a methodology for physics-based modeling of soil for accurate tire performance simulations and its validation. For this …
