DENUDATIONAL ISOSTATIC REBOUND OF INTRAPLATE HIGHLANDS - THE LACHLAN RIVER VALLEY, AUSTRALIA - DISCUSSION

Episodic terrace cutting cannot be a complex response to the steady is ostatic rebound forecast by an elastic flexure model because three ter races match epiphreatic passage levels in nearby caves. There is also some doubt about how fluvial incision rates should be extrapolated to catchment-wide rates. At the local scale of the Lachlan River highland s, active tectonic compression may be more important than flexure, whi ch is more important at a regional scale.
