| Abstract: | Complex natural resource degradation problems such as dryland salinisation require integrated management solutions. Integrated catchment modelling can be used to develop such solutions. This paper presents three models that were applied independently in the Liverpool Plains Catchment, an important crop production area, in Eastern Australia. They are a point soil-plant-water model, an economic catchment model, and a catchment hydrology model. After discussing their individual merits and limitations, the paper develops the concept of a holistic modelling framework by combining these models to gain synergy effects in analytical ability as well as applicability and implementation of results. |
