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 1, French, - surface%20de%20la%20nappe
Record number: 1, Textual support number: 1 OBS
Quand une formation encaissante sus-jacente existe, la zone de saturation n'a pas de surface libre. La surface d'une nappe souterraine libre n'est pas la surface d'eau qui, dans les matériaux perméables, se trouve, en général, au-dessus de la surface de la nappe souterraine libre. 4, record 1, French, - surface%20de%20la%20nappe
