Entropy-Based Temporal Downscaling of Precipitation as Tool for Sediment Delivery Ratio Assessment. [PDF]
Entropy (Basel), 2021 Many regions around the globe are subjected to precipitation-data scarcity that often hinders the capacity of hydrological modeling. The entropy theory and the principle of maximum entropy can help hydrologists to extract useful information from the scarce data available.

Comparison of conceptual landscape metrics to define hillslope-scale sediment delivery ratio
Geomorphology, 2012 Abstract The aim of this study was to evaluate four metrics to define the spatially variable (regionalised) hillslope sediment delivery ratio (HSDR). A catchment model that accounted for gully and streambank erosion and floodplain deposition was used to isolate the effects of hillslope gross erosion and hillslope delivery from other landscape ...

Estimating sediment delivery ratio by stream slope and relief ratio [PDF]
MATEC Web of Conferences, 2018 Nowadays, the storage capacity of a reservoir reduced by sediment deposition is a concern of many countries in the world. Therefore, understanding the soil erosion and transportation process is a significant matter, which helps to manage and prevent sediments entering the reservoir.

Simulating with a Combination of RUSLE GIS and Sediment Delivery Ratio for Soil Restoration
Environmental Monitoring and Assessment, 2023 Abstract Erosion by water is the main cause of land degradation. Landscapes degraded by erosion need to be restored in many respects, and particularly in terms of ecosystem services. From an economic and management perspective, care is needed to select priority areas and determine the means to be applied to restore them.

A GIS BASED TOOL FOR THE SEDIMENT DELIVERY RATIO COMPARISON
Italian Journal of Engineering Geology and Environment, 2021 The note deals with a new tool implementation for evaluating Sediment Delivery Ratio (SDR) in a river basin, through GRASS GIS software. The definition of a spatially distributed value of SDR is a very important task as the sediment routing can affects losses of soil productivity, increase of solid transport in stream channels, and water quality ...

Variation in suspended sediment yield across the UK – A failure of the concept and interpretation of the sediment delivery ratio [PDF]
Journal of Hydrology, 2014 Summary The sediment delivery ratio (SDR) has been a common approach developed to understand change in sediment yield and flux through a catchment. In this study we propose that the underlying concept of the sediment delivery ratio is flawed for a number of reasons: its linear extrapolation is physically meaningless; there is no evidence of the ...

Sediment Delivery Ratio from a small Semiarid Watershed of Brazil
Revista Brasileira de Geografia Física, 2021 Assessing technologies based on sediment yield in watersheds is increasingly important to determine the delivery rate. This work aimed to determine values of sediment delivery of the hydrographic basin of the river Jacu in the semiarid of Pernambuco and its relations with the soil and vegetation.

Factors influencing the sediment delivery ratio of the Three Gorges Reservoir [PDF]
E3S Web of Conferences, 2018 In recent years, the sediment delivery ratio (SDR) of the Three Gorges reservoir (TGR) has noticeably decreased as a result of the increase in water levels at the dam site and the decrease in inflow of fine particles, thereby resulting in increased reservoir siltation.

A GRASS tool for the Sediment Delivery Ratio mapping
, 2016 This work involves the implementation of a tool for evaluating Sediment Delivery Ratio (SDR) in a river basin, through GRASS GIS software. The definition of a spatially distributed value of SDR is a very important task as the sediment routing can affect solid transport in stream channels, water quality degradation, and frequency ...

DETERMINATION OF SEDIMENT DELIVERY RATIO IN DRAINAGE SYSTEM
Acta Scientiarum Polonorum. Formatio Circumiectus, 2019 Określenie ilości rumowiska, odpływającego rowami systemu odwadniającego na podstawie znanego natężenia procesów erozyjnych w zlewniach tego systemu, wymaga dysponowania wskaźnikiem dopływu rumowiska (SDR – sediment delivery ratio). W wyniku badań procesów erozji i transportu rumowiska unoszonego w rowie głównym R systemu odwadniającego Łączany ...
