The River Murray Floodplain Inundation Model (RiM-FIM) : Hume Dam to Wellington

[摘要] Executive Summary:The River Murray Floodplain Inundation Model (RiM-FIM) was created as a research and decision support tool for environmental flow management in the River Murray.The project has been funded, commissioned and developed by several organisations since beginning in 1997.RiM-FIM encompasses the River Murray floodplain from Hume Dam at Albury (Victoria) to Lake Alexandrina at Wellington (South Australia).This is the entire length of the regulated section of the River Murray (~ 2, 155 km).The model was developed using a Geographical Information System (GIS), remote sensing and hydrological modelling.Floodplain inundation extents were detected from satellite imagery for a range of flows and interpolated to model flood growth patterns.The RiM-FIM predicts the extent of flooding on the River Murray floodplain from a rang eof river flows and weir levels.it is useful for predicting the extent of inundation on the River Murray floodplain (~ 606, 000 ha) including the flow regimes of wetlands and floodplain vegetation.It allows for spatial and quantitative analysis of the flood extents to be used as an input into the management decision process.
