The need for operational reasoning in data-driven rating curve prediction of suspended sediment [PDF]

, 2012
The use of data-driven modelling techniques to deliver improved suspended sediment rating curves has received considerable interest in recent years. Studies indicate an increased level of performance over traditional approaches when such techniques are ...

An Evaluation of various developing methods for sediment rating curve and computer simulationmodels for sediment load estimation in Mazandaran basin, Iran [PDF]

علوم و مهندسی آبیاری, 2017
A sediment curving rate is a method to describe the relationship between river discharge and suspended sediment load for a particular location. The rating curves have been used to predict sediment load by hydrologists for more than sixty years (Horowitz,

Application of Hydrological and Sediment Modeling with Limited Data in the Abbay (Upper Blue Nile) Basin, Ethiopia

Hydrology, 2022
In most developing countries, biophysical data are scarce, which hinders evidence-based watershed planning and management. To use the scarce data for resource development applications, special techniques are required. Thus, the primary goal of this study

ASSESSING SUSPENDED SEDIMENT YIELD IN THE SAF SAF GAUGED CATCHMENT, NORTHEASTERN ALGERIA [PDF]

Malaysian Journal of Geosciences, 2019
Many studies on sediment transport have been carried out on Algerian rivers but few studies have been undertaken in catchments of the Northeast of Algeria. The scarcity or discontinuity on sediment transport measurements reduces knowledge about soil loss.

The erythrocyte sedimentation rate time curve: Critique of an established solution

Journal of Biomechanics, 1983
Abstract A sigmoid curve is required to characterize the time course of the erythrocyte sedimentation rate (ESR) test. The widely used ‘logistic’ form has been thought to have a theoretical foundation in a sedimentation model of Puccini et al. (1977) which claims to account for the sigmoid form without rouleaux formation. We show the curve of these
