This report documents the mapping of the extent of saltwater influence in three Hawke's Bay estuaries, the Tukituki, the Waitangi and the Ahuriri.
The current report provides a specific benchmark or reference point in time against which change over time may be assessed. These changes may be driven either by Council managed activities (such as those regulated through the resource consent process), or natural events (e.g. climate change, change in shape and extent of the estuary following an unusual hydrological event).
The extent of saltwater influence was mapped using ArcGIS interpolating continuous conductivity data collected using Odyssey CT loggers. The data collected indicates that the individual estuaries have different saltwater regimes, driven largely by their physical characteristics and the magnitude of freshwater inflows. Correlations indicate that the dominant variable influencing the extent of saltwater influence was flow in the Tukituki, flow and tide height in the Waitangi estuary and tide height in the Ahuriri estuary.

This report compiles information gathered by Hawke's Bay Regional Council on the waterways of the Karamu catchment, in addition to aquifers of the Heretaunga Plains. The Characterisation Summary (Section 2 of this report) synthesizes results by topic (e.g. water quality) across the 11 subcatchments, with key points selected for this Executive Summary. Monitoring results are then
summarized by major sub-catchment, with report sections dedicated to each:

4509 Continuous Ambient Air Quality Monitoring Summary Report 2013
Author(s): Dr Kathleen Kozyniak
Publication Date: 2 October 2013
Publication Number: 4509
HBRC contracted GNS Science to oversee the installation of three 500 mm diameter rainfall
recharge lysimeters and an instrument enclosure at Ashcott Road, Ruataniwha Plains
(Figure 1 and Figure 2). The monitoring site is located on well-drained soil, overlying an
unconfined recharge area (Griffiths, 2004; Landcare Research, 2013). Rainfall recharge
datasets from the site will complement datasets from previously installed sites in the
Heretaunga Plains at Bridge Pa, Maraekakaho and Fernhill (Figure 3). Rainfall recharge
information from the network of HBRC monitoring sites will be useful to estimate rainfall
recharge across the Hawke's Bay region to assist in groundwater management.

GNS Science was contracted to provide advisory assistance to Hawke's Bay Regional
Council (HBRC) during the installation of a rainfall recharge monitoring site in the
Ruataniwha Plains (Contract Number: RM-13-24-4540). Abigail Lovett (Groundwater
Scientist) attended the installation for a total of three days, including the 19th, 20th and 23rd
September 2013. The installation was undertaken by HBRC according to standard
procedure as detailed in Lovett and Cameron (2013), which is included with the contract.
