Observations, classification, and dynamics of furrows in cohesive sediments.

Sedimentary furrows are geologically important longitudinal bed forms which form in fine-grained, cohesive sediments of the deep- sea floor as well as in estuaries and in large lakes. These bed forms fall into broad morphological classes: those developed in muddy, cohesive sediments have steep walls and flat floors, while those developed in carbonate-rich cohesive sediments are broad with gently-sloping walls. Characteristics of furrow echo patterns are summarised and a model for furrow initiation and development in muddy cohesive sediments is presented.-after Author
