Geographic Information System (GIS) as a basis for the next generation of hydrogeological models to manage the geothermal area Waiwera (New Zealand)

Abstract. The geothermal hot water reservoir below the small town of Waiwera in New Zealand has been known to indigenous M?ori for many centuries. Overproduction by European immigrants led a level decrease and consequently artesian flow from wells seeps on beach ceased. Te Kaunihera o T?maki Makaurau Auckland Council established Thermal Groundwater Allocation Management Plan allow system recover. For sustainable operation, management regime can be informed hydrogeological models based monitoring data. underlying geological model revised according field observations an existing numerical transferred newly developed software package TRANSPORTSE. Monitoring digitally derived data have integrated geographic information (GIS).
