Altered river morphology in South Africa related to the Permian-Triassic extinction

  
Science, Vol. 289, No. 5485. (2000), pp. 1740-1743, https://doi.org/10.1126/science.289.5485.1740

Abstract

The Permian-Triassic transition in the Karoo Basin of South Africa was characterized by a rapid and apparently basin-wide change from meandering to braided river systems, as evidenced by preserved sedimentary facies. This radical changeover in river morphology is consistent with geomorphic consequences stemming from a rapid and major die-off of rooted plant life in the basin. Evidence from correlative nonmarine strata elsewhere in the world containing fluvial Permian-Triassic boundary sections suggests that a catastrophic terrestrial die-off of vegetation was a global ...

 

Effectiveness of vegetation barriers for marly sediment trapping

  
Earth Surface Processes and Landforms, Vol. 29, No. 9. (August 2004), pp. 1161-1169, https://doi.org/10.1002/esp.1108

Abstract

Vegetation barriers can be effective in trapping eroded sediment, but little knowledge exists on the characteristics of vegetation barriers efficient in trapping all sediments from an eroded zone upslope. The objective of this study is to quantify the effectiveness of vegetation barriers for marly sediment trapping. Relationships between eroded zones and vegetation barriers – composed of low vegetation, that is to say herbaceous and under-shrub layers – located downslope and sufficient to stop all the sediments eroded above, have been studied ...

 

Influence of vegetation distribution on sediment yield in forested marly gullies

  
CATENA, Vol. 50, No. 2-4. (January 2003), pp. 549-562, https://doi.org/10.1016/s0341-8162(02)00121-2

Abstract

The cover provided by forest vegetation makes it possible to fight erosion efficiently. Furthermore, vegetation barriers can also play a major role by trapping eroded sediments and thus vegetation located downslope of a gully can be important. The objective of this study is to highlight the role of vegetation distribution in a marly gully in reducing sediment loss at the outlet. To do this, sediment yield in gullies with similar geological and geomorphological components, but with different vegetation cover and distribution, ...

 

Forests and erosion: Insights from a study of suspended-sediment dynamics in an overland flow-prone rainforest catchment

  
Journal of Hydrology, Vol. 428-429 (March 2012), pp. 170-181, https://doi.org/10.1016/j.jhydrol.2012.01.039

Abstract

Forests seem to represent low-erosion systems, according to most, but not all, studies of suspended-sediment yield. We surmised that this impression reflects an accidental bias in the selection of monitoring sites towards those with prevailing vertical hydrological flowpaths, rather than a tight causal link between vegetation cover and erosion alone. To evaluate this conjecture, we monitored, over a 2-year period, a 3.3 ha old-growth rainforest catchment prone to frequent and widespread overland flow. We sampled stream flow at two and overland flow ...

 

Modelling mean annual sediment yield using a distributed approach

  
Earth Surface Processes and Landforms, Vol. 26, No. 11. (October 2001), pp. 1221-1236, https://doi.org/10.1002/esp.275

Abstract

In this paper a spatially distributed model for the calculation of sediment delivery to river channels is presented (SEDEM: SEdiment DElivery Model). The model consists of two components: (1) the calculation of a spatial pattern of mean annual soil erosion rates in the catchment using a RUSLE (Revised Soil Erosion Equation) approach; and (2) the routing of the eroded sediment to the river channel network taking into account the transport capacity of each spatial unit. If the amount of routed sediment ...

 

Sediment-yield prediction with Universal Equation using runoff energy factor

  
In Present and Prospective Technology for Predicting Sediment Yield and Sources, Vol. ARS-S-40 (1975), pp. 244-252
Keywords: energy   modelling   runoff   sediment-yield   usle  

Abstract

[Excerpt] The universal soil loss equation was developed for predicting field soil loss as a guide to conservation farm planning, but it can be used to predict sediment yield from watersheds when a delivery ratio is applied. Delivery ratios (the sediment yield at any point along a channel divided by the source erosion above that point) have been computed for some physiographic areas and related to watershed characteristics. However, the few areas studied represent only a small portion of the United ...

 

Spatially distributed modelling of soil erosion and sediment yield at regional scales in Spain

  
Global and Planetary Change, Vol. 60, No. 3-4. (February 2008), pp. 393-415, https://doi.org/10.1016/j.gloplacha.2007.05.002

Abstract

Initiated by the need to quantify erosion rates and the impacts of global changes on erosion, several attempts have been made to apply erosion models at regional scales. However, these models have often been directed towards on-site soil erosion estimates, emphasising sheet and rill erosion processes, and disregarding gully erosion, channel erosion and sediment transport. These models are therefore of limited use for the assessment of sediment yield, off-site impacts of erosion, and for the development of environmental management to control ...

 

On the dynamics of soil moisture, vegetation, and erosion: implications of climate variability and change

  
Water Resources Research, Vol. 42, No. 6. (21 June 2006), pp. n/a-n/a, https://doi.org/10.1029/2005wr004113

Abstract

We couple a shear-stress-dependent fluvial erosion and sediment transport rule with stochastic models of ecohydrological soil moisture and vegetation dynamics. Rainfall is simulated by the Poisson rectangular pulses rainfall model with three parameters: mean rainfall ...

 

Sensitivity of runoff and soil erosion to climate change in two Mediterranean watersheds. Part II: assessing impacts from changes in storm rainfall, soil moisture and vegetation cover

  
Hydrological Processes, Vol. 23, No. 8. (15 April 2009), pp. 1212-1220, https://doi.org/10.1002/hyp.7250

Abstract

The impacts of climate change on storm runoff and erosion in Mediterranean watersheds are difficult to assess due to the expected increase in storm frequency coupled with a decrease in total rainfall and soil moisture, added to positive or negative changes to different types of vegetation cover. This report, the second part of a two-part article, addresses this issue by analysing the sensitivity of runoff and erosion to incremental degrees of change (from a -20 to +20%) to storm rainfall, pre-storm ...

 

Predicting postfire sediment yields at the hillslope scale: testing RUSLE and Disturbed WEPP

  
Water Resources Research, Vol. 43, No. 11. (1 November 2007), W11412, https://doi.org/10.1029/2006wr005560

Abstract

High-severity wildfires can increase hillslope-scale sediment yields by several orders of magnitude. Accurate predictions of postfire sediment yields are needed to guide management decisions and assess the potential impact of soil loss on site productivity and downstream aquatic resources. The Revised Universal Soil Loss Equation (RUSLE) and Disturbed WEPP are the most commonly used models to predict postfire sediment yields at the hillslope scale, but neither model has been extensively tested against field data. The objectives of this paper are to ...

 

Can control of soil erosion mitigate water pollution by sediments?

  
Science of The Total Environment (June 2013), https://doi.org/10.1016/j.scitotenv.2013.05.057

Abstract

The detrimental impact of sediment and associated pollutants on water quality is widely acknowledged, with many watercourses in the UK failing to meet the standard of ‘good ecological status’. Catchment sediment budgets show that hill slope erosion processes can be significant sources of waterborne sediment, with rates of erosion likely to increase given predicted future weather patterns. However, linking on-site erosion rates with off-site impacts is complicated because of the limited data on soil erosion rates in the UK and the ...
