Sediment impacts Great Barrier Reef water quality and coral health. Erosion of gullies within a river catchment are the dominant source of sediment. This project aims to develop a novel catchment level modelling tool, allowing land managers to compare rehabilitation options and identify optimal actions. The project will generate new knowledge in applied mathematics, using innovative model emulation techniques to bring process insights to the catchment scale. Expected outcomes include a validated land rehabilitation decision making tool, benefiting both natural resource managers by increasing ability to meet Reef 2050 policy targets and landowners though development of Natural Capital Markets.

沉积物影响大堡礁水质和珊瑚健康。河流流域内的冲沟侵蚀是沉积物的主要来源。该项目旨在开发一种新的集水区建模工具，使土地管理者能够比较各种恢复方案，并确定最佳行动。该项目将产生新的应用数学知识，使用创新的模型仿真技术，使过程的见解集水规模。预期成果包括一个经过验证的土地恢复决策工具，通过提高实现珊瑚礁2050政策目标的能力使自然资源管理者受益，通过发展自然资本市场使土地所有者受益。
