Predicting soil erosion and sediment yield at the basin scale: Scale issues and semi-quantitative models
Joris de Vente,Jean Poesen +1 more
TLDR
In this article, the relation between basin area, dominant erosion processes, and sediment yield by a combination of measured sediment yield at different spatial scales in Mediterranean environments is discussed. But the applicability of these models at the basin scale is troublesome.About:

TL;DR: An unprecedentedly high resolution global potential soil erosion model is presented, using a combination of remote sensing, GIS modelling and census data, that indicates a potential overall increase in global soil erosion driven by cropland expansion.

Tolerable Versus Actual Soil Erosion Rates in Europe
TL;DR: In this paper, a modified definition of tolerable soil erosion is proposed as any actual soil erosion rate at which a deterioration or loss of one or more soil functions does not occur, with soil formation consisting of mineral weathering as well as dust deposition.

Prolegomena to sediment and flow connectivity in the landscape: A GIS and field numerical assessment
TL;DR: In this paper, two new definitions of sediment and water flux connectivity (from source through slopes to channels/sinks) with examples of applications to sediment fluxes are presented, and two indices of connectivity are operatively defined, one (IC) that can be calculated in a GIS environment and represents a connectivity assessment based on landscape's information, and another (FIC) can be evaluated in the field through direct assessment.

The sediment delivery problem revisited
TL;DR: In this article, three typical trends are identified to conceptualize the main driving forces of the relation between A and sediment yield, including land cover, land cover conditions, climate or topography, which can result in non-linear relations with A.

A meta-analysis of soil erosion rates across the world

TL;DR: In this article, a meta-analysis of published data from more than 4000 sites worldwide was carried out, revealing a negative relationship between erosion rate and the size of the study area involved; significant differences associated with differing measurement methods, with direct sediment measurement yielding the lowest erosion rates, and bathymetric, radioisotope and modeling methods yielding the highest rates; and a very important effect of the duration of the experiment.

Predicting rainfall erosion losses : a guide to conservation planning
W. H. Wischmeier,Dwight D. Smith +1 more
TL;DR: The Universal Soil Loss Equation (USLE) as discussed by the authors is a model designed to predict the average rate of soil erosion for each feasible alternative combination of crop system and management practices in association with a specified soil type, rainfall pattern and topography.

Large Area Hydrologic Modeling and Assessment Part i: Model Development
TL;DR: A conceptual, continuous time model called SWAT (Soil and Water Assessment Tool) was developed to assist water resource managers in assessing the impact of management on water supplies and nonpoint source pollution in watersheds and large river basins as discussed by the authors.

World-Wide Delivery of River Sediment to the Oceans
John D. Milliman,Robert H. Meade +1 more
TL;DR: The authors showed that rivers with large sediment loads (annual discharges greater than about $15 \times 10^{6}$ tons) contribute about $7 −times 10 −9$ tons of suspended sediment to the ocean yearly.

Geomorphic/Tectonic Control of Sediment Discharge to the Ocean: The Importance of Small Mountainous Rivers
TL;DR: In this paper, data from 280 rivers discharging to the ocean indicates that sediment loads/yields are a log-linear function of basin area and maximum elevation of the river basin.
