Suspended load and bed load in irrigation furrows

CATENA, 2005
Abstract The circulation of water in irrigation furrows is a well-understood physical process. However, theoretical understanding of sediment dynamics is less well established. This study assesses an approach to determine the sediment load in irrigation furrows, involving the use of a suction device for sampling water with suspended sediments at ...

Bed‐Load and Suspended‐Load Transport of Nonuniform Sediments

Journal of Hydraulic Engineering, 1991
Methods are available for the computation of the bed-load and suspended-load transport rates of uniform sediments. However, limited studies exist for nonuniform sediments. These studies, in general, lack simplicity, and often make use of various correction factors to be read from a series of tables and graphs.

Suspended-Load Transport

2014
The mode of sediment transport where the sediment particles are surrounded by the fluid over an appreciably long period of time is known as suspended-load transport. This chapter introduces basic concepts of sediment suspension and formulations to predict the suspended-load transport rate.

Non-Colocated path tracking in crane suspended loads

2013 IEEE International Conference on Mechatronics (ICM), 2013
This paper proposes and validates experimentally a non-time based scheme for the non-colocated path tracking control of a crane suspended load. The controller is named Delayed Reference Non-Colocated Control (DRNC) and extends the idea of the Delayed Reference Control (DRC) schemes.

Nested saturation control of an UAV carrying a suspended load

2014 American Control Conference, 2014
This paper addresses the problem of using unmanned aerial vehicles for the transportation of suspended loads. The proposed solution introduces a novel control law capable of steering the aerial robot to a desired reference while simultaneously limiting the sway of the payload.

Suspended load in flows on erodible bed

International Journal of Sediment Research, 2009
Steady state suspended-load of sediment transported in flow over erodible beds usually is treated by the advection-diffusion approach, though in recent years, it is being treated as a two-phase flow phenomenon incorporating kinetics of sediment particles.

Discrete Sampling of Bedload and Suspended Load

1989
This aspect of the program included the development of fluorescent sand tracer and suspended sediment sampling devices and procedures for their use in measuring the transport rate of sand. These devices and procedures were employed at Torrey Pines Beach and at Leadbetter Beach.

Continuous Suspended Load Sampler

1989
Knowledge of the response of sediment particles to the hydraulic forces produced by shoaling waves is essential in studies of both large and small scale sedimentation patterns along sandy coasts. While accurate fluid-flow measurements are possible in even the most energetic nearshore waters because of technological advances in commercially available ...
