Nappe (d'eau souterraine). Eaux souterraines remplissant entièrement les interstices d'un terrain poreux et perméable (l'aquifère) de telle sorte qu'il y ait toujours liaison par l'eau entre les pores. Une nappe se forme par accumulation des eaux d'infiltration au-dessus d'un terrain imperméable qui interdit leur progression vers le bas. L'eau remplit par gravité toutes les cavités accessibles du terrain jusqu'à un niveau appelé surface de la nappe. Cette tranche de terrain où toutes les cavités accessibles sont remplies d'eau est appelée zone de saturation. 1, record 2, French, - surface%20de%20la%20nappe
