The Catchment Land Use for Environmental Sustainability (CLUES) model is being transferred from the ArcMap GIS environment to ArcGIS Pro and we are looking for volunteers to help test the new model interface with a limited Beta release of the model.
The Catchment Land Use for Environmental Sustainability (CLUES) model is being transferred from the ArcMap GIS environment to ArcGIS Pro and we are looking for volunteers to help test the new model interface with a limited Beta release of the model.
NIWA’s Catchment Land Use for Environmental Sustainability (CLUES) model is a GIS-based system that predicts the effects of land-use change and farm practice scenarios on water quality and a range of socio-economic indicators at the catchment scale. CLUES allows users to create land use change and land management scenarios and view results in map or tabular displays. It was developed as a decision support tool for catchment managers, land-use planners and regulators and is available publicly for non-commercial use.
CLUES was developed by NIWA for the Ministry of Agriculture and Forestry (now part of the Ministry for Primary Industries) and the Ministry for the Environment and contains aspects of three existing water quality models (SPARROW, OVERSEER and SPASMO) as well as a socio-economic model. Various agencies contributed to the development of CLUES including AgResearch, Landcare Research, Plant & Food Research, Aqualinc Research and Harris Consulting.
CLUES is provided as a front-end interface for ArcMap and comes with a geospatial database that includes land use for the base year 2018 and stream data from the River Environments Classification, REC. The GIS platform allows geo-visualisation of both the model input data and model outputs. Users can also add their own spatial data for display and to create scenarios.
For each river reach in the REC stream network, CLUES predicts the annual average loads and yields of nutrients (total nitrogen and total phosphorus), total suspended solids and E. coli. Estimates of nutrient concentrations are also calculated.
Transition to ArcGIS Pro has required a rebuild of the model which means some of the functionality of CLUES is not yet available or is being replaced by new features. Modules have been coded for TN, TP and E. coli with a new sediment module based on NIWA’s sediment yield estimator planned for 2023. Changes that have been made include the following:
Planned further development
Ahead of the full model release in 2024, we plan to undertake the following tasks:
CLUES for ArcMap is still available for download. You will need access to ArcMap 10.6 or 10.8 to run CLUES. We are currently working on transferring CLUES to ArcPro with a new release planned for 2023.
CLUES is available for download free of charge for non-commercial use, downloading and using CLUES implies that you have read and accept the user licencing agreement. CLUES software, documentation and data files can be downloaded from the links below.
