Combined regional flood hazards extent for rivers and streams in the Wellington Region. Data supplied in Feb 2017 from GWRC Flood Protection Dept for the GWRC public flood hazard maps project. Extra extent data supplied by KCDC and WCC was added in May 2017. If you want more information about Flood Risk in the Western part of the Region, please contact...

Flood zones are identified from a combination of historic flooding records and flood modelling compiled by Wellington Water. Data has been compiled from a variety of sources and its accuracy may vary. Information supplied is to the best of Wellington Water's knowledge, and must not be used for detailed engineering design. Please contact Wellington Water...

Live river and rainfall information for the Marlborough District. Current flows are shown against know alarm thresholds.

This dataset is part of the proposed Marlborough Environment Plan, as amended by decisions. The layer identifies land subject to Level 1, 2, 3 and 4 flood hazard. For more information, check the Marlborough Environment Plan website. Symbology settings for display in GIS applications: Level 1 : Outline - None, Fill - RGB 179, 247, 255 Level 2: Outline -...

The East Cape has a history of “hits” from decaying tropical cyclones causing widespread flooding and disruption. There are also other events that are more localised and result from a weather system dumping a large volume of water in a small area. A recent study showed that there is a trend of less of these events, but when they occur more rain falls....

Stopbanks are continuous mounds of earth built near rivers to stop water from the river flooding nearby land. Americans call them levees. They may look like grassy banks, but they are actually constructed according to very specific engineering designs. When the river is in flood, they need to be able to contain the floodwaters without collapsing.

Known flooding areas throughout the Gisborne district that are not part of the official Tairawhiti Resource Management Plan flood zones.

Gisborne District Council (GDC) is required to identify areas in the coastal environment that are potentially affected by coastal hazards, over at least 100 years, as required by the New Zealand Coastal Policy Statement (NZCPS) (DoC 2010). In 2014 NIWA developed a Coastal Calculator to derive coastal-storm inundation elevations and likelihoods as a result...

Flood hazard assessments have been carried out for several areas in the District. These include the Poverty Bay Flats, Gisborne urban area, and the Mangatuna/ Wharekaka Area for the Hikuwai/Uawa River. The flood hazard varies across liable areas. Generally towards the edge of the flooded area depths are shallow and floodwaters move at slow speeds....

Council maintains a network of stopbanks, hydraulic structures and pump stations, as well as managing the river, stream and drainage channels to ensure they work as expected during floods. The overall aim is to reduce the risk of flood and erosion damage while maintaining a high quality river environment. The stopbanks on the major rivers are designed to...

Much of the settled Hawke’s Bay region is low lying and built on river flood plains. This brings the risk of flooding, which is our most common natural hazard - a severe storm or flood happens every 10 years on average. Major storms affect wide areas and can be accompanied by strong winds, heavy rain or snowfall, thunder, lightning, and rough seas. They...
