Assessment of the stream conditions associated with the Hudson Street Gully erosion control works

Abstract

Before the commencement of the Hudson Street Gully erosion control works there were two waterfalls and a 58–m long culvert on the Hudson Street Gully Stream. The works have replaced the 3-m waterfall at the confluence of the stream with the Waikato River with a 75-m concrete pipe culvert with a fall of 3.45 m, and a 10-m long culvert between the new, 75-m long culvert and the original culvert. The 2.6-m waterfall with its overhanging lip that is 9 m upstream of the original Hudson Street Gully culvert remains unaltered.
