soils and surface condition data. The sediment delivery ratio (SDR) is used as a logical tool to integrate the factors that affect the production of sediment from the gross ero-sion occurring in a watershed. Traditionally, the SDR is defined as the ratio of sediment load delivered to the wa-tershed outlet (sediment yield) to gross erosion occurring

Data from the area indicate that the sediment delivery ratio (SDR) can be estimated as a function of two variables, ψ (the product of catchment area and channel slope) and A g (the temporally averaged gully area for the period). Sediment input from gullies was determined from a well defined relationship between sediment yield and gully area.

The sediment delivery ratio (SDR) is a bond of slope erosion and channel sediment transport but exhibits poor dynamic applicability, which makes it difficult to accurately identify the spatio-temporal evolutions of sediment yield in an ecological restoration watershed with different governance degrees.

This work involves a 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 solid transport in stream channels, water quality degradation, and frequency increase of natural disasters such as debris flows and mudflows.

A variety of land use and its change plays a vital role in the water quality of lakes. Especially, urban and built-up and cultivated areas influence the water quality within the lake basin. To understand sediment and nutrient processes using sediment delivery ratio (SDR) and nutrient delivery ratio (NDR) models under the InVEST software suite, sediment export and nutrient export were examined ...

A sediment delivery ratio (SDR) is assigned based on characteristics of flow from the gully and is applied to estimate sediment reduction. Sediment-attached phosphorus reduction is estimated from the sediment reduction, default phosphorus content of 1.0 lb of phosphorus per 1 ton of soil, and a correction

The sediment delivery ratio (SDR) is a key link between slope erosion and river sediment transport but the accurate quantification of sediment yield in different catchments has been hampered by a lack of dynamic multi-scale information on SDR.

The Sediment Delivery Ratio (SDR) is fraction of gross erosion (interill, rill, gully and stream erosion) that is expected to be delivered to the outlet of the river. The sediment transfer and deposition can be modelled with sediment distribution models such as WaTEM/SEDEM.

The watershed sediment delivery ratio (SDR) reflects the transport status of eroded soil in a watershed, and it is an important parameter in studying the relationship between basin erosion and sediment yield of rivers. This review study mainly focuses on China.
