A flume study was conducted using a soil, yard waste compost, and an erosion control compost to investigate the response to concentrated flow and determine if the shear stress model could be used to describe the response. Yard waste compost (YWC) and the bare Cecil soil (CS) control responded to concentrated laboratory runoff similarly in rill formation, and the shear stress model was useful in...

Pyrogenic carbon (PyC) constitutes an important pool of soil organic matter (SOM), particularly for its reactivity and because of its assumed long residence times in soil. In the past, research on the dynamics of PyC in the soil system has focused on quantifying stock and mean residence time (MRT) of PyC in soil, as well as determining both PyC stabilization mechanisms and loss pathways. Much o...

A Cellular Automata model for soil erosion by water, SCAVATU, was developed. It involves a larger number of states in comparison to the previous models: alti-sidering some of the most significant processes of the phenomenon: water flow, infiltration, soil erosion by water flow, sediment transport and deposition. Simulations gave encouraging results, in agreement with the findings of other studi...

Basically, water erosion is one of the most significant environmental problems in the world. The major variables affecting soil erosion are climate, soil, vegetation, and topography. Of these, vegetation and, to some extent, soil and topography may be controlled. However, for adequate intervention, reliable and representative model parameters and running conditions are necessary, which requires...

Soil erosion is a crucial problem in Nepal where more than 80% of the land area is mountainous and still tectonically active. Although deforestation, overgrazing and intensive agriculture, due to population pressure, have caused accelerated erosion, natural phenomena inducing erosion, such as exceptional rains, earthquakes and glacial-lake-outburst flooding in the high Himalayas are also common...

Erosion processes and their impact are driven by a multitude of biophysical factors that are poorly understood in the Andean highlands. The first attempt to assess soil erosion rates in Peru was made by Felipe-Morales et al. (1977) using runoff plots. Since then, very few erosion investigations have followed and reference to Andean soil erosion is often criticized because of the lack of quantit...

This paper presents an integrated assessment model aimed at evaluating land degradation by water erosion in dehesa rangelands in the Iberian Peninsula. The model is built following the system dynamics approach. The degradation risk is likened to the probability of losing a certain amount of soil within a number of years, as estimated over a great number of stochastic simulations. Complementary ...

Distributed erosion models are potential tools for identifying soil sediment sources and guiding efficient Soil and Water Conservation (SWC) planning. However, the uncertainty of model predictions has yet to be resolved. Splash erosion is one of the most important mechanisms in soil loss. In this study, monthly splash detachment rates were predicted using the Morgan, Morgan and Finney (MMF) emp...

A standalone version of the Wind Erosion Prediction System (WEPS) erosion submodel, the Single-event Wind Erosion Evaluation Program (SWEEP), was released in 2007. A limited number of studies exist that have evaluated SWEEP in simulating soil loss subject to different tillage systems under high winds. The objective of this study was to test SWEEP under contrasting tillage systems employed durin...
