The flooding type infiltrometers normally consist of tubes or concentric rings which are driven into the ground to depths of 15-21 in. These tubes are usually about 9 in. in diameter and 18-24 in. in length. Water is applied to the tube from graduated burettes and maintained at a constant head (...) over the soil surface. Readings of the water level in the burettes taken at successive time intervals permit direct determination of infiltration volumes and rates. 1, record 1, English, - flooding%20type%20infiltrometer
Les infiltromètres [à submersion] sont habituellement constituées de tubes ou cylindres concentriques qu'on enfonce dans le sol à des profondeurs de 15 à 21 pouces. En général, ces tubes ont environ 9 pouces de diamètre et 18 à 24 pouces de longueur. Des burettes graduées, qui maintiennent le niveau d'eau constant (...) au-dessus de la surface du sol, servent à alimenter les tubes en eau. Des lectures du niveau d'eau à des intervalles successifs permettent de déterminer directement les volumes et les taux d'infiltration. 1, record 1, French, - infiltrom%C3%A8tre%20%C3%A0%20submersion
