Scottish Environment Protection Agency (SEPA) Flood Map

The link below will connect you to SEPA’s Flood Risk Management mapping system. Firstly, zoom in to an area of your choice or use the search function to view the flood data. Then proceed to follow steps 1 and 2 provided in the menu which will allow you to select the flood data you would like to be displayed. Use the legend at the right hand side to interpret the colours given on the map.

This could be a useful tool in a Geography lesson. Pupils could assess the impact of flooding from a hypothetical proposed new road (considering river, surface water and perhaps even coastal flooding).

SEPA Water Level Database

The link below will connect you to an overview of the available data collection sites. Select ‘Map Search’ from the blue headings. Pan in and click a red dot to provide a summary of the associated water level. Specific tabular (spreadsheet) data can be downloaded by clicking ‘Level Data’ in the table.

This could be a useful tool in a Geography lesson. This could be used in conjunction with the SEPA Flood Risk Management Map and SEPA Rainfall Data Map. Pupils could evaluate the water levels, average rainfall and other physical features they can spot (relief, built up areas / flood plains etc.) and assess the flooding risks of two ‘proposed roads’ and determine the least intrusive location. They could then use SEPA Flood Risk Management Map which will show the current flood risk.

SEPA Water Environment Hub – Classification Database

The link below will connect you to SEPA’s Water Environment Hub mapping system. Using the search ‘Pan Narrative’ on the left hand side will allow you to sieve for official classifications of quality, physical condition, fish migration, water flows and levels on different types of waterbodies.

This could be a useful tool in a Geography lesson. Pupils could identify the classification, physical condition, fish migration etc. of the river closest to their home.

SEPA Bathing Water Areas

The link below takes you directly to SEPAs Bathing Waters results for Scotland map. Clicking on a dot will provide you with the Escherichia coli (E.coli) and Intestinal enterococci levels as well as the historical classification record. The URL ‘Bathing Water profile, including further information and maps’ contains in depth information, images and maps of the selected waterbody.

This could be a useful tool in a Geography or biology lesson. Pupils could identify a bathing water location closest to their home and the levels of E.coli and enterococci present; as well as its classification status. Pupils could use the Water Environment Hub (above) to identify any other characteristics of this waterbody. Pupils could then research E.coli and enterococci and their associated health implications.

SEPA Rainfall Data Map

The link below will take you directly to SEPAs Rainfall data for Scotland mapping system. Clicking on a dot will display the associated rainfall data for the station on the right hand side.

Scotland’s Environment Interactive Map

The link below will take you directly to the Scotland’s Environment interactive mapping system. This mapping system provides a lot of data concerning air, water, land and people and the environment. Under the Water drop-down box on the left will provide accessible layers of energy, fishing, quality, heritage and monitoring and classification layers. Zoom in to an appropriate scale to activate the selected layers. Clicking on the activated layers will provide you with another drop box containing additional information.

This could be a useful tool in a Geography lesson. Pupils could list as much information possible about a particular water body and report any results (i.e. needs better management or it is likely to flood). Google maps is a useful tool to determine characteristics about rivers i.e. meandering could mean it is slow moving, hydropower stations on the tributaries could result in low flow, flood plains / built up areas could result in increased flood risk.

Modelled Water Levels Data

The spreadsheet below provides the Annual Exceedance Probability (AEP) data (flooding probability for different events) for the watercourse. The 50% AEP levels represents a flood that is likely to occur every two years, the 3.33% event every 30 years, the 0.5% event is an extreme flood occurring every 200 years, and the 0.5% event including climate change uses predicted climate figures to estimate future extreme flooding events.

This data could support a geography lesson. The pupils could be asked to calculate the difference between maximum levels for different flood events. Pupils could also use the pdfs and mark on the map the associated water level points. Pupils could then be asked to use the topographical contour maps and predict the geographical extent of the flooding at different locations i.e. where the maximum water level height lies in comparison with the surrounding land.
