On the dynamics of quasi-steady gravity currents flowing up a slope

Quasi-steady gravity currents propagating first on a horizontal and then up sloping boundary are investigated by means of theoretical analysis laboratory experiments. The bottom slope ranged from 0.18 to 1 full- partial-depth configurations were considered. developed model, using the depth averaged momentum equation, provides new physical insight into importance different forces that act current accounts for component along slope, whose effect increases with both angle ratio ambient fluid depths. height decreases linearly up-slope distance spatial rate decrease, expressed shape parameter is determined theory, measured at which stops. This found depend only it not dependent It can be used calculate velocity reached current. shown front all performed experiments predicted theory indicating remains valid equal 1.
