In the Howe of Tay and Tilt (Pont manuscript 23). ca. 1590 he makes three frustrated attempts at mapping the river around Castle Menzies (Weem/Aberfeldy) just after it leaves Loch Tay and before Dunkeld. Dominic Habron, who works at SEPA, is one of those involved on hydrocoding and error identification for the SEPA project. His methods then used both photographic questionnaire and Graphic Information Systems analysis. A key part of this initiative involves the development and application of a standard hydrological coding (shortened to ‘hydrocoding’) scheme, which is to be used to reference sampling locations in relation to main river catchments, individual rivers and each other. The adoption and use of such a scheme will allow easy access to defined subsets of a catchment’s data, such as data for a particular subcatchment or river.
The ability to uniquely identify any location on the river network will greatly improve SEPA’s data analysis and reporting capabilities and will likely be an important reference system for the forthcoming European Water Framework Directive. It is envisaged that one of the first major uses of the dataset will involve automation of the water quality classification and reporting procedures. The efforts being expended on the project in these relatively early stages will pay dividends in the future in terms of improved information retrieval and catchment management capabilities.
SEPA Science staff have been involved in the development of the UK Chemical Strategy which was launched in December and aims to speed up the process of assessing the risks of chemicals already in use. a lack of some of the most basic information about chemicals entering the environment, even those entering it in high volumes.
Key elements behind the Strategy are a precautionary approach (in which chemicals which cause an unacceptable risk to the environment must be phased out); better information achieved through voluntary industry agreements, reinforced by legislation if progress is not satisfactory; and greater transparency with a new Chemicals Stakeholder Forum to be set up by summer 2000 involving representatives of all groups interested in the impact of chemicals on the environment and human health Technical mixtures were manufactured in the UK until the mid-1970’s when their use in most applications ceased, even so, significant quantities remain sealed, for example, inside electrical equipment.
