Figure 3: Predicted sand fluxes using two independent dune growth mechanisms.
From: Unravelling raked linear dunes to explain the coexistence of bedforms in complex dunefields
(a) Resultant sand flux QI at the crest of dunes growing in the bed instability mode. (b) Resultant sand flux QF along the crest of elongating dunes. Solid (wind tower W1) and dashed (wind tower W2) lines are the sand flux predicted from the wind data shown in Fig. 1c. Dots are the sand flux derived from the morphodynamics of individual dunes between 2006 and 2014. The coloured areas show the 90% confidence intervals centred on the mean sand flux values 〈QI〉=48.3 m2s−1 and 〈QF〉=34.0 m2s−1.
