"""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) <doi:10.1007/s00477-017-1505-x>. 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 <doi:10.2134/jeq2008.0337>)."""
