Dual Behavior of Suspended Sediment Concentration in a Regulated River
Better understanding of suspended sediment transport processes allows for better management of both rivers and coasts. Based on field data and sediment transport energy theory, this study presents an analysis on the suspended sediment hysteresis in the Lower Tenryu River of Japan in connection to the channel carrying capacity of suspended sediment and morphological characteristics. The transpor...
متن کاملThe effect of properties of sediment type on the relationship between suspended sediment concentration and radiance
A laboratory experiment was designed to determine the spectral characteristics of different types of sediment suspended in water in the visible and near infrared wavelengths (0.45-0.9 /xm) using a fourchannel radiometer. Field collected sediments were resuspended in water to produce different concentration levels for the measurement of radiance. Spectral measurements of turbid water showed a di...
متن کاملHigh-frequency turbulence and suspended sediment concentration measurements in the Garonne River tidal bore
The study details new sediment concentration measurements associated with some turbulence characterisation conducted at high-frequency in the undular tidal bore of the Garonne River (France). Acoustic Doppler velocimetry was used, and the suspended sediment concentration was deduced from the acoustic backscatter intensity. The field data set demonstrated some unique flow features of the tidal b...
متن کاملSediment Flushing at the Nakdong River Estuary Barrage
The Nakdong River Estuary Barrage (NREB) prevents salt-water intrusion but causes sedimentation problems in the Lower Nakdong River in South Korea. Its mitigation requires mechanical dredging to maintain the flood conveyance capacity during typhoons. This analysis focuses on the possibility of replacing mechanical dredging with sediment flushing through gate operations changes at NREB. The new ...
متن کاملComparison and evaluation of intelligent models for river suspended sediment estimation (case study: Kakareza River, Iran)
Sediment transport constantly influences river and civil structures and the lack ofinformation about its exact amount makes management efforts less effective. Hence,achieving a proper procedure to estimate the sediment load in rivers is important. We usedsupport vector machine model to estimate the sediments of the Kakareza River in LorestanProvince and the results were compared with those obta...
