Abstract

The aim of this study is to analyse the geomorphic responses of the ephemeral Bushrangers Creek, central western New South Wales, Australia, following the 2002 removal of 15 m high dam. Comparisons of pre- and post-dam removal survey data indicate that there has been repeated base-level lowering upstream of the former dam site. Longitudinal profiles of the thalweg before and after dam removal show an average bed lowering of 0.5 m and reveal a 90 m long channel with a slope in excess of two-times greater than the pre-dam removal channel has formed upstream of the former dam wall
