APSIMAPSIM is internationally recognised as a highly advanced simulator of agricultural systems. It contains a suite of modules, or components, which enable the simulation of systems that cover a range of plant, animal, soil, climate and management interactions. It is undergoing continual development, with new capability added to regular releases of official versions over time. Its development and maintenance is underpinned by rigorous science and software engineering standards.Soil-plant-animalVal Snow, AgResearch; Hamish Brown, Plant and Food; Dean Holzworth, CSIRO Ecosystem Sciences, Toowoomba, Queensland, Australia, http://www.apsim.info/Wiki/
AquiferSimAquiferSim is a GIS-based steady-state regional scale groundwater flow and contaminant transport model. It was developed as part of the multi-organisation IRAP (Integrated Research for Aquifer Protection) Project.Groundwater, OtherSimon Woodward, Lincoln Ventures Ltd / Linda Lilburne, Landcare Research.
BNZCatchment-scale water quality model for sediment and nutrients. The daily USDA GLEAMS model is run for each unique grid cell and contaminant are then routed to the stream and down the stream network with attenuation.Soil-plant-animal, Streams and riversSandy Elliott, NIWA
C-CALMCatchment Contaminant Annual Loads Model Urban water quality model with a GIS platform (ArcMap - versions available for 9.3 and 10) which estimates the annual loads of TSS, zinc and copper (total, dissolved and particulate) generated by different land covers at the stormwater catchment scale. Based on the Auckland Council spreadsheet CLM model and has the same choice of land covers which represent different landuses and yields for those covers. Allows users to choose between a range of stormwater treatment options and the proportion of each land cover treated to reduce annual loads.
