Fig. 5: Impact of constriction on excess flow thickness and excess volume over time.
From: Lava effusion in mountainous terrain generates flow backup and excess inundation
The excess flow thickness behind the constriction for (a) 100GS and 100GSB, b 98GS and c 100GLY, as a function of time since reaching the constriction, tc. In all cases, the backup thickness (xc) initially increases rapidly and then approaches a plateau value. The largest excess xc occurs in experiments with narrower constrictions (high R values) and higher flux (Qi) controlled by high pump speeds and steeper slopes. Also plotted is the excess flow volume (Vc) behind the constriction for (d) 100GS and 100GSB, (e) 98GS, and (f) 100GLY, as a function of time since reaching the constriction, tc. The largest excess Vc occurs in experiments with the highest R values.
