1914J. L. Rich in Jrnl. Geol. XXII. 470 The In-grown Meander Valley is one whose stream, which may or may not have inherited a meandering course from a previous cycle, has developed such a course or expended its inherited one. Thus, as the stream sunk its channel lower and lower into the bed-rock, the meanders were continually growing or expanding. The term ‘in-grown’ has been chosen to express this idea. 1954W. D. Thornbury Princ. Geomorphol. vi. 145 Two types of incised or inclosed meanders are generally recognized: (1) entrenched or intrenched meanders.., which show little or no contrast between the slopes of the two valley sides of a meander curve, and (2) ingrown meanders.., which exhibit pronounced asymmetry of cross profile with under⁓cut slopes on the outside of the meander curves and slipoff slopes on the inside. 1960B. W. Sparks Geomorphol. ix. 225 Ingrown meanders are more slowly incised, due to less rapid downcutting or to more resistant rocks. |
