Monitoring baseline suspended sediment in forested basins: the effects of sampling on suspended sediment rating curves

Rating curves are widely used for directly assessing changes in the suspended sediment delivery process and indirectly for estimating total yields. Four sampling methods were simulated over a 31-day record of suspended sediment from the North Fork of the Mad River near Korbel, California. The position and size of the four groups of plotted slope/intercept pairs indicated differences in bias and...

The effect of land use and discharge changes on the coefficients of suspended sediment rating curve in Zagros forest areas

Extended abstract   1- Introduction   The forests of the Zagros vegetation area cover about six million hectares (40%) of Iran's forest area, which is dominated by oak species. These forests are exposed to a number of threats, including land use change, deforestation, over grazing, deliberate and unintentional fires, pest and disease attacks, and climate change. Although accurate and timely...

Suspended Sediment Estimation for Rivers using Artificial Neural Networks and Sediment Rating Curves

The methods available for sediment concentration and flux estimation are largely empirical, with sediment rating curves being the most widely applied. In this study, a comparison is made between artificial neural networks (ANNs) and sediment rating curves for two rivers with very similar catchment areas and characteristics in the north of England. Data from one river are used to estimate sedime...

تعیین مناسب‌ترین روش برآورد رسوب معلق بر اساس آماره‌های خطاسنجی (مطالعه موردی-تعدادی از زیرحوزه‌های کشف‌رود)

The phenomena of erosion, sediment transport and sedimentations have tremendously destructive effects on environment and hydraulics structures. In general, sediment transportation depends on river discharges, but the proposed equations inherited with large errors. To evaluate the suspended sediment loads and an optimized model on them, in this research, data were collected from some sub-watersh...

Quantifying total suspended sediment export from the Burdekin River catchment using the loads regression estimator tool

[1] The loads regression estimator (LRE) was introduced by Wang et al. (2011) as an improved approach for quantifying the export of loads and the corresponding uncertainty from river systems, where data are limited. We extend this methodology and show how LRE can be used to analyze a 24 year record of total suspended sediment concentrations for the Burdekin River. For large catchments with high...
