Less-frequent and inadequate sampling of sediment data has negatively impacted the long continuous records required for design operation hydraulic facilities. This data-scarcity problem is often found in most river basins Taiwan. study aims to propose a parsimonious probabilistic model based on copulas infill daily suspended loads using streamflow discharge. A copula-based bivariate distributio...

Sediment balance is essential for understanding changes in river morphology and ecosystems related services depending on them. However, the currently used methods to quantify riverine sediment processes are not adequate enough. We have examined regime of Danube River, particularly suspended yield. This parameter can be calculated based stage or discharge using a yield rating curve; however, unc...

Jangkok River, a very important river for irrigation purposes in Lombok Island Indonesia is experiencing rapid change the land use of its watershed. The conversion trees into seasonal crops watershed causes decrease carrying capacity and reduces ability to prevent soil erosion. Environmental damages such as erosion sedimentation along are becoming increasingly difficult control. This paper prop...

Cop Abstract: Event sediment transport and yield were studied for 45 events in the upstream part of the 260 km agricultural Koga catchment that drains to an irrigation reservoir. Discharge and turbidity data were collected over a period of more than a year, accompanied by grab sampling. Turbidity was very well correlated with the sediment concentrations from the samples (r = 0.99), which allowe...

this review provides the basic principle and rational for roc analysis of rating and continuous diagnostic test results versus a gold standard. derived indexes of accuracy, in particular area under the curve (auc) has a meaningful interpretation for disease classification from healthy subjects. the methods of estimate of auc and its testing in single diagnostic test and also comparative studies...

The effective discharge constitutes a key concept in river science and engineering. Notwithstanding many years of studies, a full understanding of the effective discharge determinants is still challenged by the variety of values identified for different river catchments. The present paper relates the observed diversity of effective discharge to the underlying heterogeneity of flow regimes. An a...
