Scottish legislation (Section 17) of the Flood Risk Management (Scotland) Act 2009 dictates that records of culverts must be created and maintained. Specifically: (1) Every local authority must prepare a map which shows (or more than one map which, taken together, show) relevant bodies of water and sustainable urban drainage systems in its area. (2) Each map must - (a) be prepared by such date as the Scottish Ministers may direct, (b) be prepared at a scale that the authority considers most appropriate, and (c) contain such information and be in such form as the Scottish Ministers may specify in regulations. (3) A local authority must, from time to time, review and where appropriate update the map (or maps) prepared for its area under subsection (1). (4) A local authority must make available for public inspection the map (or maps) prepared under this section for the time being applicable to its area. (5) In this section and section 18 - “relevant body of water” - (a) means - (i) a body of surface water other than a stretch of coastal water, or (ii) a body of underground water forming part of a watercourse (but not including a watercourse which is wholly underground), but (b) does not include sewers and drains which drain into sewers, “sustainable urban drainage system” has the meaning given in section 59(1) of the Sewerage (Scotland) Act 1968 (c.47). Most Local Authorities have contributed (natural) culvert data to the new OS MasterMap Water Network Layer either through providing data to the Scottish Government or through the James Hutton Institute. As this data is now live, a mechanism for managing/maintaining/updating this data needs to be put in place. SCOTS (Society of Chief Officers for Transportation in Scotland) have approved for this dataset to be managed by the Spatial Hub and any amended data can be uploaded (and potentially downloaded) before being shared with OSMA members and the OS. We have initially created a point and line data layer representing the data we have been sent by some LAs. However, we really need line data in order for it to be merged into the OS MasterMap Water Network Layer data in due course. The LA "culverts" data as included in the OS MasterMap Water Network Layer is also available for LAs to download and use as part of this dataset

Hydrographic elements, including river basins and sub-basins.

Blue-Green Algae Warning Notices for Lochs within The Highland Council Area

Inland Electronic Navigational Chart (IENC) means: the database, standardized as to content, structure and format, for use with inland electronic chart display and / or information systems operated onboard of vessels transiting inland waterways. An IENC is issued by or on the authority of a competent government agency, and conforms to standards [initially] developed by the International Hydrographic Organization (IHO) and [refined by] the inland ENC Harmonization Group (IEHC). An IENC contains all the chart information necessary for safe navigation on inland waterways and may contain supplementary information in addition to that contained in the paper chart (e.g. sailing directions, machine-readable operating schedules, etc) which may be considered necessary for safe navigation and voyage planning.

This dataset provides assessment of over 5600 watercourse along the west coast of Scotland for their nationally/internationally important water-loving oceanic bryophyte (moss and liverwort) communities. The approach is applied in line with Scottish Natural Heritage’s 'Planning for Development - Service Statement'. The aim of the database is therefore to help users take account of Europe's most important watercourses for these species before selecting sites for potential hydro development. Individual watercourses, or sites that contain multiple watercourses, have been assessed for either their known (categories A-C) or potential (categories D-E) importance. The category descriptions provide clear guidance as to whether a watercourse is known to hold bryophytes or likely to be of low bryological importance, and whether further survey is recommended. This assessment only considers the impact of water abstraction on water-loving oceanic bryophytes and additional consideration should be given to direct impacts of construction on important bryophyte habitats (e.g. springs/flushes, ancient woodland, deadwood, bogs). The data was derived from the database saved in eRDMS B796293.The full methodology is described in SNH Commissioned Report 449b: Bryological assessment for hydroelectric schemes in the West Highlands (2nd edition).

After distinguishing between groundwater containing nitrate and groundwater without nitrate, the first step of the method allows for the classification of groundwater with iron (anoxic) or without iron (oxic). Water types having both iron and nitrate at either low or relatively high concentrations at the same time are classified as 'mixed'. The method can either end here or if needed continue in a second step for mixed samples. The second step considers NH4 and O2 concentrations. After applying the methodology to individual sampling points the results were aggregated to lithological units. The results of these calculations and how the redox potential map was build are described in this report.
