The height of water is still very important at the top of the valley
even if the most important quantity of water lies in lowest part of it.
We can remark that the line of maximum height goes between the two banks
of the valley.
Then, after 10000 seconds :
The water continues moving towards the lowest parts of the valley. The
water height is now twice more important than it was for the precedent
visualisation. The design of the flow of water is quite clear now, it follows
the lowest line of the valley. The regime of the flow begins to be established.
For 19200 seconds (5 hours and 20 minutes), we have :
We can now consider that the flow regime is established. The banks of
the valley are almost empty of water (only 4 mm of water). The whole quantity
of water follows the path we have designed for it, and the height of water
is quite constant with the time.
The sending of a flood is now possible with this established regime for the flow.
