A catchment modelling approach integrating surface and groundwater processes, land use and distribution of nutriehnts: Elimbah Creek, Southeast QueenslandMartin Labadz PhD 2007 - 2010 
Faculty Institute for Sustainable Resources/Faculty of Science and Technology Supervisor/s Aspro Malcolm Cox, Prof Peter Grace Thesis Abstract Human activities are contributing to higher nutrient loads can have a significant impact on the ecological quality of a coastal drainage system and its estuary, often leading to the eutrophication of surface waters.
This study will contribute to the understanding of nitrogen (N) and phosphorus (P) cycling in soils, surface water and groundwater in a multiple land-use catchment in a subtropical setting (Elimbah Creek). It will identify N and P sources, concentrations, as well as the forms, controls on release, distribution and fixation. The study will therefore consider temporal and spatial mechanisms, such as seasonal changes, geology, soils, geomorphology and land use. The influence of the water balance on catchment processes will be tested as well as surface water– groundwater interaction. A major aim of the investigation is to determine whether N and P released within the freshwater catchment are subject to transport into the estuary and adjoining marine environments. |
