Abstract

The present work aims to understand the potential effects of bathymetry and geometry on the total water level in Manukau Harbor in the present and future projections of sea-level rise. Our study site is in the southwest region of Auckland. The tide is mesotidal amplitude, and the estuary has a prismatic geometry, extensive tidal zone, and depths ranging from 30m (close to the estuary entrance) to 1m in the inner channels. We analyzed the observed total water level in 2 tide gauges. The first one, located outside the Harbor, is the Anawhata tide gauge — managed by the National Institute for Water and Atmospheric Research (NIWA) —; the second, located in the inner estuary, is the Onehunga tide gauge, managed by the Auckland Council. Our methods can be divided into two sessions, the data and numerical analysis.
