Quote: Over the last couple of years there has been significant discussion about the coupling of the earth surface with the atmosphere and in particular the feedback between soil moisture and the atmospheric processes such as rainfall through vegetation. Older work in NSW has suggested a decrease in the stream flow due to increased re-vegetation. However, some recent Australian simulation modeling work suggests a decrease in rainfall and increase in temperature due to land clearing (McAlpine 1997). In addition, large irrigation areas could increase the local rainfall and decrease the annual mean temperature. This suggests a strong coupling between the land surface and the atmosphere. This project first analyses NSW rainfall data for evidence of changes during the 20th century, followed by simulation modeling to prove that these changes are due to variations in landuse in NSW. Finally, scenarios looking at the impact of increased re-vegetation in combination with climate change on local rainfall and streamflow are analysed taking into account the level of atmospheric feedback.
