Description

This paper describes progress on techniques in the modelling of sediments andnutrients to inform management effort. It describes a catchment-scale model known asCatchMODS, and the integration of knowledge from a range of collateral sources to informits development and application. A full description of the model, including its hydrologic,sediment and nutrient modules, is presented. The paper describes how knowledge fromfield-based studies is incorporated to support the modelling. Knowledge is generated from:(i) water quality monitoring; (ii) sediment tracing of critical source areas and relativesubcatchment contributions (using geochemical, and mineralogy techniques); and (iii) fieldinvestigation, particularly landscape measurement. This knowledge is used for modelconceptualisation, correct parameterisation and performance testing.
