Any ideas on how to model flow over a mill pond damn? Like so:
It's a long uniform straight feature so the random waterfall/rapids construction techniques aren't applicable. Long clear filaments laid all paralell along the top of the mill dam, curving downward? And how would you do that? The foam and water ripples below the flow are not needed, this picture happens to show an energetic flood over the dam. In a low flow case, minimum foam produced.
Maybe somebody already did one of these.
