Objectives:
The objectives of the research are to:
1. develop and improve calibration of the existing hydrodynamic model;
2. establish parameterisation of sediment transport processes;
3. undertake preliminary assessment of transport pathways and distribution of wastes
4. investigate dispersion modelling.
5. identify data gaps and provide recommendations for further research

Project Summary:
SEPA has undertaken previous investigations in this field which have led to the development of a near-field/mid-field prediction tool (AutoDEPOMOD) for the assessment of chemical and faecal contamination levels resulting from fish-farm wastes. The proposed research will provide an alternative means of validating AutoDEPOMOD predictions as well as providing a means of assessing levels of contamination in the far-field. The proposed research will focus on a defined geographical region such that a range of hydrographic conditions are accommodated within the model domain. There is currently significant uncertainty associated with the far-field fate of contaminated material thus SEPA currently operate a precautionary approach in the regulation of waste generated by fish-farms. An accurate description of the physical processes controlling dispersion of contaminants, particularly in the far-field, is required to ensure the fish-farming industry around the Scottish coastline is managed in a sustainable manner. The research will provide a site-specific model that can also be used to investigate generic issues related to fish-farm activities around the Scottish coastline. The results of the study will advance technical understanding of the far-field dispersion processes of waste from fish-farms and provide a means of validating existing research tools developed for the investigate processes in the near-field/mid-field region.
