Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller
Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller
Theses : Honours
The Bremer river catchment, on the South-coast of Western Australia, is typical of most river catchments in this region in that it has been seriously affected by sedimentation, salinisation and eutrophication brought on by the gradual dominance of agricultural land management practices. Vegetated rehabilitation and changed agricultural land management practices (ie minimum / zero tillage) have now been widely adopted throughout the catchment in response to these degradation issues. This study examined the potential impact minimum / zero tillage, vegetated rehabilitation and remnant vegetation could have on both a farm and catchment wide scale. A Geographical Information System was developed …
Fuel Characteristics Of Rehabilitated Bauxite Mines In Western Australia, Sarah J. Collins
Fuel Characteristics Of Rehabilitated Bauxite Mines In Western Australia, Sarah J. Collins
Theses : Honours
This investigation assessed the fuel characteristics of Alcoa of Australia's rehabilitated bauxite mines in the south-west of Western Australia. The study determined the fuel loads, their composition and structure. The characteristics of fuel were determined, their relationship with time ascertained, and the similarity of these characteristics to the jarrah forest ecosystems that they have replaced was discussed. Pits aged from four to twenty years since rehabilitation were assessed. Predictive models were developed to allow the rapid assessment of fuel. The fuel characteristics in two controlled bum areas were also assessed to how much fuel would burn in a fire and …
