HEL
Highly Erodible Land Model
HEL identifies land that is highly erodible. It identifies steep land that is at risk of mass movement. It identified land that should be under forest to... Read More The Highly Erodible Land (HEL) system identifies land highly susceptible to mass-movement erosion using a combination of the erosion terrains derived from the NZLRI database, a 15‑metre digital...

KerDST
KerBabel™ Deliberation Matrix
The KerDST Deliberation Matrix aims to help a group of stakeholders understand a particular issue or problem through a qualitative assessment of the problem including... Read More The KerDST (Deliberation Support Tool) including the KerBabelTM Deliberation Matrix (DM) and the KerBabelTM Indicator Kiosk (KIK) is an on-line tool offering users a multi-stakeholder...

NZeem®
New Zealand Empirical Erosion Model
NZeem® is an empirical model that predicts mean annual sediment yield from a given catchment, based on annual rainfall, type of terrain and percentage of woody... Read More NZeem® partitions the New Zealand landscape according to the factors controlling erosion: rock type, land form (especially slope angle), rainfall and land cover. The erosion co‑efficient (a) is... Read More Land Natural Hazards erosion, sediment, rivers, farm plans, soil conservation
SPASMO
Soil Plant Atmosphere System Model
SPASMO models the transport of water, microbes and solutes through soils integrating variables such as climate, soil, water uptake by plants in relation to farm and orchard practices,... Read More SPASMO, which has been in continuous development for over 20 years and is currently used by six Regional Councils for allocation of irrigation water. It has also...

SSYE
Suspended Sediment Yield Estimator
A New Zealand national GIS ‘layer’ to enable reconnaissance-scale estimation of suspended-sediment yields from New Zealand’s rivers and streams. It has been developed by NIWA in collaboration with... Read More SSYE uses a raster-based GIS layer of specific suspended-sediment yield (SSY, t/km2/y) from New Zealand’s rivers and streams has been generated based on gauged sediment yields at over...

MCA
Multicriteria Analysis
Multicriteria analysis or multiobjective decision making is a type of decision analysis tool that is particularly applicable to cases where a single-criterion approach (such as cost-benefit analysis) falls... Read More MCA describes any structured approach used to determine overall preferences among alternative options, where the options accomplish several objectives. In MCA, desirable objectives are specified and corresponding attributes...

Cost Benefit Analysis
Cost benefit analysis is a decision making tool that aims to assess the value of a proposal or competing proposals on a consistent basis. Read More Cost-benefit analysis is a method for organising information to aid decisions about the allocation of resources. Its power as an analytical tool rests in two main features: costs...
