Based on d=0.5 mm, z = 10 m (height of anemometer), z0 = 10-4, ρsand = 2380 kg/m3, ρair = 1.23 kg/m3, porosity = 0.4, average height of dunes = 2.0892 m:
|
u*,crit (critical shear velocity for transport) |
0.350 m/s |
|
qs,mean (expected annual mass flux of sand) |
4078 kg/m/yr |
|
qs,dir (expected dune migration direction) |
21.7° (trigonometric direction, ENE) |
|
c (expected dune celerity) |
1.37 m/yr |
