This paper describes the potential and limitations of the HEC6T sediment transport model to describe changes in channel scour and deposition following the Cerro Grande fire near Los Alamos, New Mexico. The results indicate that it is capable
of modeling sediment transport in ephemeral channels following wildfire.

MEFIDIS (short for Physically Based Distributed Erosion Model) was developed to simulate the consequences of climate and land-use changes for surface runoff and erosion patterns during extreme rainfall events. The model relies on physically based

Impact of expected increase in precipitation intensities on soil loss - results of comparative model simulations

Climatic change ; Comparative study ; Erosion rate ; Germany ; Model ; Precipitation ; Saxony ; Simulation ; Soil erosion
Simulated precipitation for the 2031-2050 time period is used to model soil loss, and results are compared to soil loss based on 20 years of measured precipitation from 1981 to 2000. The simulation results allow the impacts of climate change
sites in Saxony, based on the EROSION 2D model (Schmidt J., 1990).

The AA. describe a dataset that offers possibilities for improved evaluation and parameterisation of spatially distributed soil erosion models. The dataset combines rainfall, runoff and sediment discharge data collected at the outlet and field
surveys within the catchments that describe soil surface charcteristics and soil erosion features. The paper dicusses and illustrates the use of the dataset to narrow uncertainties associated with model predictions.

Arizona ; Climatic change ; Erosion rate ; Europe ; Land use ; Model ; Plant canopy ; Precipitation ; Runoff ; Soil erosion ; United States of America ; Watershed
The AA. investigated the response of 7 soil erosion models to a few basic precipitation and vegetation related parameters using common data from one humid and one semi-arid watershed. Principal results were that soil erosion is likely to be more

The aims of this study were to evaluate the potential impacts of climate change on soil erosion, surface runoff, and wheat productivity in central Oklahoma. The Water Erosion Prediction Project (WEPP) model was run for 4 climate scenarios including

In this study, changes in management were assigned based on previous studies of crop yield, optimal planting date, and most profitable rotations under climate change in the Midwestern United States. The soil erosion model appeared to underestimate
