AbstractWind erosion is an important component of coastal dune morphodynamics, and has been subject to research since decades (e.g., Bagnold 1941; Han et al. 2009). However, many expressions to predict fluid threshold velocity for wind erosion are not generally valid. For instance, Han et al. (2009) showed that some expressions struggle to predict the threshold velocity for tropical and/or humid coastal areas. We hypothesize that a shear strength limit equilibrium approach can incorporate the effects of moisture content, particle sorting and shape, slope angle, and cohesion into a general equation that would be applicable to a range of environmental and soil conditions. The objective of this study is to test this hypothesis using data sets published by McKenna-Neuman and Nickling (1989).
