ModelsLASCAM
LASCAM (Large-scale catchment model) can be used to predict the long-term impact of land use and climatic changes on the daily trends of stream flow and water quality (represented by salt, sediments and nutrients). The model is unique in that it was developed for Australian conditions that can make predictions on water quantity and quality for a large catchment. The model simulates the hydrological processes at the subcatchment scale, before being aggregated to yield the response of the entire catchment.
Recent applications include the prediction of the water yield, salinity and sediment and nutrient outflows from the Swan-Avon.River Basin in Western Australia (catchment size 140,000 km2. It is presently being used as a management tool to evaluate a number of catchment management options for sediment and nutrients inputs to a number of catchments feeding the Swan River, near Perth. LASCAM has also been used to assess land use changes in tropical environments (Sarawak, Malaysia).
