QUE SIGNIFIE WATER TABLE EN ANGLAIS
Niveau hydrostatique
La nappe phréatique est la surface où la pression de l'eau est égale à la pression atmosphérique. Il peut être visualisé commodément comme la «surface» des matériaux de subsurface qui sont saturés d'eau souterraine dans un voisinage donné. Cependant, les conditions saturées peuvent s'étendre au-dessus de la nappe phréatique car la tension de la surface maintient l'eau dans certains pores en dessous de la pression atmosphérique. Les points individuels sur la nappe phréatique sont généralement mesurés comme l'altitude à laquelle l'eau augmente dans un puits tamisé dans les eaux souterraines peu profondes. Les eaux souterraines peuvent provenir des précipitations infiltrantes ou des eaux souterraines qui s'écoulent dans l'aquifère. Dans les zones où les précipitations sont suffisantes, l'eau s'infiltre dans les espaces poreux du sol en passant par la zone insaturée. À des profondeurs croissantes, l'eau remplit plus de pores dans les sols, jusqu'à ce que la zone de saturation soit atteinte. Dans des matériaux perméables ou poreux, tels que les sables et le substrat rocheux fracturé, la nappe phréatique forme un plan relativement horizontal. Au-dessous de la nappe phréatique, dans la zone phréatique, les unités perméables qui produisent des eaux souterraines sont appelées aquifères.
définition de water table dans le dictionnaire anglais
La définition de la nappe phréatique dans le dictionnaire est la surface de la partie saturée d'eau du sol, qui suit généralement les contours de la surface terrestre sus-jacente. Une autre définition de la nappe phréatique est celle d'un terrain décalé ou à cordes qui a une moulure conçue pour évacuer l'eau de pluie du mur en dessous.
