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...

This dataset is a subset of data, prepared by the Institute of Geological and Nuclear Sciences for the Hawke's Bay Regional Council, designed to help the Council plan to reduce the adverse impacts of future earthquakes. This data set refers to polygons in Hawke's Bay within each of which the ground has been assigned a uniform class of response to seismic...

This dataset is a component of a much larger dataset, compiled by the Institute of Geological and Nuclear Sciences for the Hawke's Bay Regional Council. This component refers to polygons in the Hawkes Bay Region within which the outcropping rocks are of Quaternary age and of one class. Each polygon is associated with a code indicating the class of the...

In 2009 Tonkin & Taylor Ltd were engaged by Hawke’s Bay Regional Council to undertake a preliminary assessment of the bank stability over a 12km reach of the lower Wairoa River, extending from approximately 3km downstream to 9km upstream of the SH2 bridge in Wairoa town.The purpose of the study is to provide a preliminary assessment of the existing...

Tsunami (pronounced tsu - nam - ee) is a Japanese word meaning 'harbour wave'. It describes a series of fast travelling waves caused by large disturbances on the ocean floor, such as earthquakes, landslides or volcanic eruptions. In the deep ocean tsunami pass almost unnoticed, but as they approach land and therefore shallower coastal waters, they change...

The Hawke's Bay Regional Council commissioned Tonkin & Taylor to undertake a regional hazard assessment using high resolution aerial survey of large areas of the cliff coastline and georeferenced photogrammetric analysis was carried out for other areas, enabling mapping of Cliff - shore hazard zones along the Hawke's Bay coastlineA delineation of the...

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...

This dataset represents the location and extent of the inland boundary of ‘Coastal Hazard Zone 1’ (CHZ1) identified in the Hawke's Bay Regional Coastal Environment Plan 2013 (‘RCEP’). The RCEP has been prepared for the purposes of assisting the Hawke's Bay Regional Council with its roles and responsibilities under the Resource Management Act. Any party...

The Coastal Environment means an environment in which the coast is a significant element or part, and includes: (a) the coastal marine area; (b) any areas identified as being affected by, or potentially affected by, coastal flooding or coastal erosion; (c) any of the following: (i) tidal waters and the land above mean high water springs; (ii) dunes; (iii)...

The RCEP has been prepared for the purposes of assisting the Hawke's Bay Regional Council with its roles and responsibilities under the Resource Management Act. Any party...

This dataset represents the inland boundaries of ‘Transition Hazard Zones’ (THZ1 and THZ2) identified in the Hawke's Bay Regional Coastal Environment Plan 2013. The RCEP has been prepared for the purposes of assisting the Hawke's Bay Regional Council with its roles and responsibilities under the Resource Management Act. Any party relying on this...

An aquifer fills with water from rain or melted snow that drains into the ground. In some areas, the water passes through the soil on top of the aquifer; in others, it enters through joints and cracks in rocks. The water moves downward until it meets less permeable rock. Aquifers act as reservoirs for groundwater. Water from aquifers sometimes flows out...

Shows the general location of known wells and bores in the Hawke’s Bay Region. Data is usually obtained where a consent has been granted and the bore construction proceeded (Current Bore Permits). As part of the consent process drillers return the data to Hawke’s Bay Regional Council. Each point contains basic summary information about the well or bore...

This dataset was created as a geospatial template to facilitate the development of a Water Allocation Framework for Hawke’s Bay Regional Council. Based on tributary catchments, these zones allow the establishment of specific rules for minimum flows and allocation limits. NIWA’s River Environment Classification was used to define each zone based on...

The New Zealand Land Resource Inventory (NZLRI) is a national database of physical land resource information. It comprises two sets of data compiled using stereo aerial photography, published and unpublished reference material, and extensive field work: An inventory of five physical factors (rock type, soil, slope, present type and severity of erosion,...
