Bed-load measurements on large, sand-bed rivers in the United States

E3S Web of Conferences, 2018
The movement of bed forms (sand dunes) in large sand-bed rivers is being used to determine the transport rate of bed load. The ISSDOTv2 (Integrated Section Surface Difference Over Time version 2) methodology uses time sequenced differences of measured ...

Parameter Optimization of a Bed Load Transport Formula for Nestos River, Greece

Proceedings, 2018
In the Second EWaS International Conference (June 2016, Chania, Crete, Greece), the bed load transport formula of Meyer-Peter and Müller (1948) was calibrated with respect to the bed roughness coefficient for Nestos River.

A Formula for The Maximum Rate of Bed-load Transport on Smooth and Fixed Bed

PROCEEDINGS OF HYDRAULIC ENGINEERING, 1994
This paper describes a new formula for the calculation of the maximum rate of bed-load transport on smooth and fixed beds. The transport rate in unit width is expressed as the product of the volume of the moving particles on unit area of bed surface and their mean advancing velocity.

Correction to “A general power equation for predicting bed load transport rates in gravel bed rivers” [PDF]

Water Resources Research, 2007
[1] In the paper ‘‘A general power equation for predicting bed load transport rates in gravel bed rivers’’ by Jeffrey J. Barry et al. (Water Resources Research, 40, W10401, doi:10.1029/2004WR003190, 2004), the y axis for Figures 5 and 10 was incorrectly labeled and should have read ‘‘log10 (predicted transport) – log10 (observed transport).’’ In ...

Effect of sampling time on measured gravel bed load transport rates in a coarse‐bedded stream [PDF]

Water Resources Research, 2005
This study empirically quantified the effect of sampling time on measured transport rates and fitted rating curves based on results obtained from bed load traps deployed for 2, 10, and 60 min in a coarse‐bedded stream. As expected for a skewed distribution of transport rates, 2 min deployment underpredicted transport rates obtained from 10 and 60 min ...

Influence of Suspended Sediment Load on Roughness Coefficient and Intensity of Flow Turbulence (Case study: Haraz, Rostamabad and Beheshtabad Rivers) [PDF]

محیط زیست و مهندسی آب, 2020
Estimating the effect of sediment transport, especially suspended load, is important in river planning and management. The aim of this study was to investigate the effect of suspended sediment load on the roughness coefficient and the intensity of flow ...

Improvement of Sickle Cell Disease Care Mitigates the Healthcare Utilization Induced by Increased Prevalence: Experience of a Tertiary Pediatric Center

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) has undergone major changes in the last decades. Its prevalence has been steadily increasing and numerous advances have been made in the management of the disease. However, the effect in real‐life setting of these major changes is unknown, particularly in a Canadian environment. Procedure We aimed to assess

Improving a multi-grain-size total sediment load model through a new standardized reference shear stress for incipient motion and an adjusted saltation height description [PDF]

Earth Surface Dynamics
Modelling sediment transport is important to understand how fluvial systems respond to climatic change or other transient conditions such as catastrophic sediment release.

Experimental Study on Uniform and Mixed Bed-Load Sediment Transport under Unsteady Flow

Applied Sciences, 2020
The scouring and deposition of sediment caused by unsteady flows (e.g., storm waves and floods) produces many secondary disasters. The resultant bed-load movement exhibits different transport laws compared with that by steady flow.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.
