Fine sediment transport and management [PDF]

, 2016
This chapter considers the key concepts to develop an improved understanding of the fine sediment loads of rivers. The key concepts are non‐capacity and supply‐controlled nature of fine sediment transport, the significance of grain size, sediment ...

A Method for Calculating Water Demand for Sediment Transport Based on the Principles of River Dynamics

, 2023
Sufficient water is pivotal in maintaining the stability of boundaries in sandy river systems. However the current methodologies employed for computing the water demand for sediment transport in rivers frequently neglect this component.

Modeling the dynamics of soil erosion and size-selective sediment transport over nonuniform topography in flume-scale experiments [PDF]

, 2011
Soil erosion and the associated nutrient fluxes can lead to severe degradation of surface waters. Given that both sediment transport and nutrient sorption are size selective, it is important to predict the particle size distribution (PSD) as well as the ...

Experimental Study on the Characteristics of Sediment Transport and Sorting in Pressurized Pipes

, 2021
Sediment transport in pipes is an effective engineering measure used to reallocate water–sediment resources and is widely used in reservoir flooding and sediment discharging, river dredging, floodplain area deposition, as well as other projects.

Sediment transport trend and its influencing factors in coastal bedrock island sea areas-a case study of Chudao island, China

Frontiers in Marine Science, 2023
Coastal bedrock islands sea areas have a unique natural environment, frequent human activities, and complex sedimentary dynamic processes. In this paper, we select the Chudao Island sea area off the coast of Shandong Peninsula, China, as a typical ...

Several understandings for sediment transport capacity by overland flow

Shui kexue jinzhan, 2018
Sediment transport capacity of overland flow, which is the maximum equilibrium sediment load that a flow can transport, is a key concept for developing process-based soil erosion models because it plays a pivotal role to determine soil detachment rate ...

Wave simulation for the design of an innovative quay wall: the case of Vlorë Harbour [PDF]

Natural Hazards and Earth System Sciences, 2017
Sea states and environmental conditions are basic data for the design of marine structures. Hindcasted wave data have been applied here with the aim of identifying the proper design conditions for an innovative quay wall concept.
