Overview

KMR is seeking to produce advanced tools and geospatial layers that enable the prioritisation of sediment mitigation and remediation actions on farms, enabling targeted implementation to reduce the rate of sediment delivery to the Kaipara Moana Catchment (see Figure 1).

The key technical and operational vehicle for achieving this outcome is the procurement and creation of high-resolution heat maps of 1) active erosion, 2) delivery pathways for the sediment, to form 3) A priority index for treatment or mitigation geospatial reference called the Kaipara Moana Sediment Remediation Layer.

There has been a significant investment in the procurement and development of relevant datasets held by NRC and Auckland Councils including LiDAR information and other geospatial data holdings. It is proposed through this RFP the relevant datasets are brought together in order to simplify farm planning and target implementation, please note this proposal identifies some important datasets that still need developed.

The successful consultant(s) will also be asked to propose a methodology and implement to a yet to defined area, using satellite data timeseries interferometric synthetic aperture radar (InSAR) to identify and assess the relative magnitude of ground elevation change related to mass movement and erosion across the Kaipara Moana catchment over time (initial 12-month period and after historic and significant known weather events in the recent past event dates).


Please refer to KMR supporting documentation for Sediment Risk Layer to explain some of the potential approaches.
