Vegetated Filter Strip and Erosion Model

Empirical models for runoff, erosion, and phosphorus loss across a vegetated filter strip, given slope, soils, climate, and vegetation (Gall et al., 2018) . It also includes functions for deriving climate parameters from measured daily weather data, and for simulating rainfall. Models implemented include MUSLE (Williams, 1975) and APLE (Vadas et al., 2009 ).

Vegetated Filter Strip and Erosion Model

This series of daily timestep models links:

  • rainfall simulation (Poisson or Markov chain models)
  • temperature simulation (simple Fourier function)


  • soil water storage based on soil properties, rainfall, and crop evapotranspiration
  • runoff generation


  • two field-scale erosion models

    • C-Q model
    • MUSLE


  • vegetated filter strip model removing sediment


  • phosphorus loss model (APLE)

While the models can be calibrated for particular fields, the main objective is to assess the relative effect of vegetated filter strips on soil erosion and phosphorus loss under different soil texture and climatic conditions. Our focus is on regional identification of high risk areas and assessment the role of vegetated filter strips as a best management practice, rather than on accurately simulating particular field conditions.
