Description :
Much controversy exists in literature concerning the processes by which tunnel valleys evolve, and a number of theories now exist in this regard. This article aims to evaluate critically the literature on tunnel valleys, focusing specifically on the major theories which attempt to explain their formation. Before doing so, however, it summarizes salient aspects of tunnel valley geomorphology, and the sedimentology of their infills. Tunnel valleys incised into both bedrock and unconsolidated sediments are discussed.
