The LAMSAT model was used to study the relationship between cover and runoff for pastoral catchments in the Northern Territory. A good treatment of the statistical indicators for the optimisation of the runoff parameter CN2 is presented. The scatter in the cover-CN2 function obtained is believed to be due to the differences in the cultural history of the catchments studied. Similar studies are also discussed.
