Further technical guidance This page brings together a number of ancillary guidance documents and previous email bulletin information relating to modelling of marine fish-farms for CAR licence applications. Auxiliary biomass sampling transect In areas where the tidal residual current is weak, the auxiliary transect (site-specific sampling 2) may be aligned along a bearing reciprocal to the primary

SEPA publishes a long-term river water quality indicator, based on a network of sites covering 253 water bodies (rivers or sections of rivers). This indicator is based on a consistent set of five water quality parameters which are sensitive to organic pollution, nutrients and toxic substances, and which provide a measure of species diversity across approximately 10% of all water bodies. Monitoring In 2011, the Scottish Environment Protection Agency (SEPA) established an indicator of river water quality based on a network of sites covering 253 water bodies (rivers or sections of rivers), which account for approximately 10% of all water bodies. The indicator is based on a consistent set of five water quality parameters which are sensitive to organic pollution, nutrients and toxic s

Marine aquaculture modelling Computer modelling is used as a guide to determining licensed discharge quantities of anti-parasitic chemicals and organic waste arising from marine fish-farm operations. The modelling tools promoted by SEPA provide robust predictions in most cases, requiring relatively little site-specific information. Nevertheless, the quality of the model outputs is dependent upon g

We are continually working to develop and improve our knowledge on flood risk and flooding impacts and to identify new technologies to better support our flooding work. As the strategic flood risk management authority in Scotland we are continually working to develop and improve our knowledge of the sources and impacts of flooding. We have developed a knowledge base of methods, guidance and summaries that may be useful to responsible authorities, academic projects and consultants delivering flood risk management projects, which can be accessed below.
