This document reports on the rebuilding and calibration of the
new numerical model, HAM2 (Hutt Aquifer Model 2). It offers an
improved calibration facilitating in the reassessment and
refinement of the sustainable and safe yield of the Waiwheteu,
and Moera Aquifers. The report provides an understanding of
river recharge processes and an improved understanding of
the effects of abstraction on groundwater levels under various
river recharge conditions. It also contributes towards the
process of reviewing the minimum allowable Waiwhetu
Aquifer water level at the Petone foreshore.
