Flooding is a serious problem in Scotland. Dundee City Council is one of the authorities responsible for making sure local flood risk is recognised and acted upon.
What were the challenges?
- Establishing joined up working between a large number of organisations.
- Ensuring it supports its communities during floods, as well as flood protection and mitigation projects.
- Accessing effective spatial data tools to help implement flooding policies.
What was the solution?
Dundee City Council has saved, by use of the SDRN information, an initial outlay of £9,000 and over the last two years licencing fees in the region of £3,000. Offsetting staff time in creating our own GIS mapping layer for water body clearance and repairs against lost time in training on proprietary software, has saved a further £1-2k.Ross Speirs, Senior Engineer,, City Development Dept., City Engineers Division
The Scottish Detailed River Network (SDRN) was set up by Ordnance Survey and a number of Scottish stakeholders who consequently devised OS MasterMap Networks Water Layer to give a complete hydrological centre line for Scottish rivers.
It sits with other Ordnance Survey products such as OS MasterMap Topography Layer and is part of the One Scotland Mapping Agreement, providing a consistent framework to those responsible for meeting the requirements of the Flood Risk Management (Scotland) Act 2009, including Dundee City Council.
What were the outcomes?
- More detailed analysis, including flow rates.
- Joined up working through a consistent national dataset that meets statutory requirements.
- Detailed records of the maintenance of the council’s waterbodies and watercourses.
- Savings of £10,000 to £15,000, with similar potential savings possible for a further 31 local authorities.
