English

Subject field(s)
  • Geomorphology and Geomorphogeny
  • Glaciology
DEF

A landscape characterized by swarms of closely spaced drumlins, distributed more or less an echelon, and commonly separated by small marshy tracts.

CONT

Review of published descriptions of drumlin fields suggests that the following conditions are important to drumlin growth :(1) compressive longitudinal and possibly extending transverse strain rates in the ice,(2) thin ice such as occurs near the glacier margin, and(3) high pore-water pressure in the subglacial sediments.

French

Domaine(s)
  • Géomorphologie et géomorphogénie
  • Glaciologie
CONT

Les drumlins sont rarement isolés; lorsque leur concentration est très intense, on parle alors de champs de drumlins.
