VALLEY AQUIFER [3 records]

Record 1 2012-04-13

English

Subject field(s)
  • Hydrology and Hydrography
  • Geomorphology and Geomorphogeny
DEF

The condition of a region in which little or none of the surface drainage reaches the sea.

CONT

Storm water flowing down the plateau edges reaches sand-blocked fossil valley bottoms where it accumulates into small pools and subsequently recharges the underlying aquifer. This hydrographic feature, called endoreism, is ubiquitous in this region : it is induced by gentle slopes, aeolian sand deposits and the small annual number of rainfall events.

Fait, pour une région, de ne pas avoir d'écoulement des eaux vers une mer ouverte.

CONT

L'endoréisme est une conséquence du relief (cuvettes fermées), du climat (forte évaporation), des sols (perméabilité, fortes infiltrations). Le centre de l'Eurasie est le principal domaine de l'endoréisme [...]

Record 2 2008-09-30

English

Subject field(s)
  • Hydrology and Hydrography
  • Geology
CONT

Bounded aquifers. Pumping tests sometimes have to be performed near the boundary of an aquifer. A boundary may be either a recharging boundary(e. g. a river or a canal) or a barrier boundary(e. g. an impermeable valley wall). When an aquifer boundary is located within the area influenced by a pumping test, the general assumption that the aquifer is of infinite areal extent is no longer valid.
