Summary
[edit]DescriptionVue subaquatique de la Créquoise section très encroûtée le 10 aout 2017 Lamiot 03.jpg |
Français : Vue subaquatique de la Créquoise, affluent de la Canche, dans le Pas-de-Calais (département 62, France) sur une section très encroûtée, dans une zone de bord de route ("Rue principale") urbanisée (village de Royon) le 10 aout 2017.
Localement le fond est complètement colmaté par un biofilm bactérien (biominéralisation), comme si une couche de quelques millimètres de béton avait été coulée. Ce jour là l'eau est laiteuse (période pluvieuse). Le niveau est bas (10 cm environ) English: Underwater view of "La Créquoise", a tributary of the Canche in the Pas-de-Calais (department 62, France) on a very encrusted section in a roadside area ("Rue Principale" in village Royon, August 10, 2017) Locally the bottom is completely clogged with a bacterial biofilm (biomineralization), as if a layer of a few millimeters of concrete had been poured. On that day the water is milky (rainy period). |
