<\/P>

A TUFLOW hydraulic model was developed to simulate flood response across the Raupo Drainage Scheme in Kaipara District. This includes the town of Ruawai and surrounds, which are protected from the Wairoa River with a series of stopbanks and floodgates. These structures were included in the model, which was simulated for design events including the 1% (100 year), 2% (50 year), 10% (10 year) and 20% AEP (5 year), as well as the 1% AEP with Climate Change (100 year + CC) using a rainfall-on-grid approach.<\/SPAN><\/P>

The model outputs are able to identify the potential flooding extents, depths and velocities and can be used to assess the impact on the built environment, infrastructure, and community as well as, subsequently, aid in the development of effective mitigation measures.<\/SPAN><\/P>

This layer is the 10 year extent river flood hazard polygon output from the model.<\/SPAN><\/P>
