Abstract

A 3D numerical model of the flow in estuaries and coastal seas has been developed. Several options have been included for the turbulence closure. The first part of the paper describes the model and its validation against existing models. The model is then applied to the Hauraki Gulf and the second part of the paper describes this application and the development of a field work program for calibration. The model has been developed as a tool for predicting wind generated surface currents. This will provide a tool for determining water quality issues in a body of water, which is used as a major recreation area. 1 Introduction The Hauraki Gulf is a shallow sea bounded in the west, south and east by New Zealand's North Island (see Fig 1). It is the gateway to New Zealand's
