Wind Erosion in Western Queensland Australia

Chapter 3 – Modelling Land Erodibility Review• That the models selected cover those across the full range of spatial scales in winderosion modelling applications (from the field to global scales);• That the models contain a representative range of land erodibility and dust sourceparameterisations, employing emission schemes developed from a range of approaches;• That the emission schemes contain a representative sample of empirical and theoreticalformulations; and• That the models selected have been developed for a variety of physical environmentsincluding cultivated lands, rangelands, and broader desert landscapes.Figure 3.1 illustrates the spatial and temporal scales at which the wind erosion modelsreviewed in this chapter operate.Figure 3.1 Space-time plot showing the spatial and temporal scales of wind erosion models reviewedin this chapter. Light gray boxes represent field scale models (Section 3.2), white boxes representregional scale models (Section 3.3), and dark gray boxes represent global scale models (Section 3.4)The first models reviewed are field scale models. These include empirical models designed tosimulate single erosion events at scales of 10 2 to 10 3 m 2 . The second group are the local to70
