A waterline network computation.
The high probability of precence of a waterline is in black.
Next slide is a zoom on the Mazamet region, the left big black area.
The observed waterline network is superimposed in white lines. The constructions
are superimposed in black lines.
The computed waterlines fits the observed waterlines .
The first big confluent (slightly to the south-east, right limit of Mazamet)
gathers the Arnette from the south, the Thore from the lower east, the
Arn from the upper east.
Remember that Mazamet developed a strong industry in wool in the northern
and northern-western zones. This activity involved nocive products in big
quantities so here 'Flood is Pollution'.
The computed waterlines shows other possible ways for the Thoré
( lower right ).
