Source sentences:
text: Since there are less fine-grained deposits near the source, this is a place where aquifers are often unconfined (sometimes called the forebay area), or in hydraulic communication with the land surface.
text: Typically (but not always) the shallowest aquifer at a given location is unconfined, meaning it does not have a confining layer (an aquitard or aquiclude) between it and the surface.
text: Where the aquifer is unconfined or thinly confined, infiltrating water dissolves the rock and transmissivity
text: In the St. Francois Mountains area where the aquifer is unconfined, water from precipitation can move downward into the aquifer.
text: The aquifers are unconfined, and have variable transmissivity from about 9 to 90 m2/d, and specific capacity values of the order of 1 to 10 m3/d/m.
text: In the latter area, aquifers in the upper part of the system lie immediately below the modern land surface and are unconfined, whereas deeper parts of the system may be locally confined or semiconfined by extensive till sheets.
text: The recharge potential is greater where the till-confining units are thin or breached by sand and gravel bodies, and greater still where aquifers are unconfined.
text: The aquifer may be unconfined beneath a standing water table, or confined by an impermeable or weakly permeable horizon.
text: These aquifers are typically unconfined.
text: The aquifers are typically unconfined.
text: The aquifers are typically unconfined.
text: The aquifer is unconfined and the water table typically between 10 m and 30 m below the ground surface.
