Modeling of streamflow- suspended sediment load relationship by adaptive neuro-fuzzy and artificial neural network approaches (Case study: Dalaki River, Iran) [PDF]

Desert, 2015
Modeling of stream flow–suspended sediment relationship is one of the most studied topics in hydrology due to itsessential application to water resources management.

Comparison of sediment rating curves and sediment yield in subbasins of the Itacaiúnas River Watershed, Eastern Amazon

RBRH, 2021
Understanding the hydrosedimentological dynamics of tropical rivers is a challenge in the Amazon due to its remote and difficult-to-access areas. This study was based on data collected from 16 hydrosedimentological control sections in the 6 subbasins ...

Anabranching and maximum flow efficiency in Magela Creek, northern Australia [PDF]

, 2004
Anabranching is the prevailing river pattern found along alluvial tracts of the world's largest rivers. Hydraulic geometry and bed material discharge are compared between single channel and anabranching reaches up to 4 times bank-full discharge in Magela

Regionalization of sediment rating curve for sediment yield prediction in ungauged catchments

Hydrology Research, 2013
The main objective of this research is to regionalize the sediment rating curve (SRC) for subsequent sediment yield prediction in ungauged catchments (UCs) in the Lower Mekong Basin. Firstly, a power function-based SRC was fitted for 17 catchments located in different parts of the basin.

Trend analyses with river sediment rating curves

Hydrological Processes, 2014
AbstractSediment rating curves, which are fitted relationships between river discharge (Q) and suspended‐sediment concentration (C), are commonly used to assess patterns and trends in river water quality. In many of these studies, it is assumed that rating curves have a power‐law form (i.e.C = aQb, whereaandbare fitted parameters).

Risk Analysis of Sediment Load Dynamics in the Shaharchay River Basin: Implications for Sustainable Water Management [PDF]

Journal of Hydraulic Structures
In the current study, Sediment load and the related hazards were studied in the Shaharchay River basin, a sub-basin of Lake Urmia, northwestern Iran. The various statistical and modeling methodologies were used to analyze discharge and sediment load data

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

Analysis of Stage–Discharge Relationship Stability Based on Historical Ratings

Hydrology, 2020
We explored the stability of the rating curves at six streamflow gauging sites in the state of Iowa, USA, to examine temporal variability of their stage–discharge relationships. The analyzed sites have up to 10 years of rating and shift records.

Assessing the effects of climate change on Assessing the effects of climate change on suspended sediment values in some watersheds of Ardabil provincet values in some watersheds of Ardabil province [PDF]

نشریه جغرافیا و برنامه‌ریزی, 2020
Introduction Estimation of the rivers sediment load has high complexity due to effecting different parameters in this aspect. Regarding the power relationship between discharge data and suspended sediment load use of sediment rating curves is one of the ...
