The New Zealand Water Model (NZWaM) – a new water modelling approach
Models have an important role to play in water management in New Zealand.
To be useful, models need to be both flexible and complex; flexible because they are needed for a wide range of purposes, and complex because they need to simulate complex natural and man-made systems (Figure 1). Ideally, these models will have a modular design, so that sub-models that represent hydrological, climatic, water quality, ecological and other processes can be added.
