Curvature is transformed into a 'nominal migration rate' through multiplication with a migration rate (or erodibility) constant; in the Howard and Knutson, 1984 paper this is a nonlinear relationship based on field observations that suggested a complex link between curvature and migration rate.</p></br></br><p>In the 'meanderpy' package we use this linear relationship between the nominal migration rate and curvature, as recent work using time-lapse satellite imagery suggests that high curvatures result in high migration rates (Sylvester et al., 2019).</p></br></br><p>You can read more about the model, find references at: https://csdms.colorado.edu/wiki/Model:Meanderpy.<p></br></br><p>There is a keynote lecture on the concepts behind this model that you can watch here: </br>https://csdms.colorado.edu/wiki/Presenters-0433</p>this model that you can watch here: https://csdms.colorado.edu/wiki/Presenters-0433</p>)
