METHODOLOGY
3.1 Modelling Approach
The hydraulic model prepared for this study utilised a linked 2D version of the TUFLOW HPC (Heavily
Parallelised Compute) model. For this flood study, a Direct Rainfall (also known as Rain on Grid) modelling
approach has been utilised; rainfall data inputs with model losses defined based on catchment surface
characteristics generate surface runoff, which is then hydraulically routed through the model topography. More

Dry conditions in South Taranaki caused by the current La Nina weather pattern could mean further restrictions on how much water can be taken from rivers, Taranaki Regional Council has warned. The environmental watchdog is keeping a close eye on rainfall levels, soil moisture, river flows and climate across the region, with most of the Council’s monitoring sites recording less rain than usual over the last three months. Council data for the lowest rainfall sites shows Pātea recorded 61% of
