Impacts on sediment transport of proposed expansion of the Port of Tauranga shipping channels and wharves

Abstract

We report results of an examination of the effects of proposed dredge-channel and wharf extensions in the Port of Tauranga (Figure 1). In previous work, we undertook a calibration and validation of a hydrodynamic model for Tauranga Harbour. The work used the hydrodynamic package Delft3D in depth-averaged mode (see Mullarney and de Lange, 2018, for details). The effects of the proposed developments on the hydrodynamics within the Harbour were examined and compared to flows with present-day bathymetry and wharf configurations.
