Our vision is for towns and cities to use nature-based, blue-green solutions to absorb and safely convey rainwater. This will: help strengthen their resilience to the intense downpours they face under climate change minimise the risk of polluting sewage spills by keeping rainwater out of sewers create fantastic places for people to live and work Urban wastewaters Over the past 20 years, SEPA has

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

Continuous water quality monitoring equipment was deployed in the inner Clyde estuary adjacent to Govan in 2011. Low dissolved oxygen concentrations are known to occur in the inner Clyde estuary at this location as a result of the decomposition of organic wastes from discharges and urban run off. Limited mixing between fresh water and more dense saltwater leads to large differences between the sal

List of data published by SEPA. Links to access data itself or applications that show the data We publish a range of datasets related to the environment, and we are continually reviewing and adding to this list. Please use our online form to contact us if you cannot find the dataset you require. We have a Corrections policy for handling revisions and corrections to the statistical summaries we produce. Our User engagement policy specifies how we engage with users to ensure our statistics ar

The SEPA Marine National Environmental Monitoring Buoy Network provides real time, high frequency environmental data from strategic locations around the coast, as part of SEPA obligations to monitoring the marine environment. What is being monitored? Continuous monitoring equipment gathers dissolved oxygen, water temperature, salinity and chlorophyll-a data at regular intervals. The data is stored

SEPA often receives environmental event notifications for issues for which are the statutory responsibility of other organisations. To help you get to the right place quickly the table below provides a quick guide to a number of issues, together with how you can contact the right organisation.

Groundwater This type of flooding is caused by water rising up from underlying rocks or flowing from springs. Groundwater is generally a contributing factor to flooding rather than the primary source. This map shows you where groundwater could influence the duration and extent of flooding from other sources. It does not show where groundwater alone could cause flooding.

Floodplain Storage Shows areas where there is the potential for floodplain storage. This is where flood water may be stored and slowed by natural features of the land. This map will be used in the Flood Risk Management Planning process to select the most appropriate action to take to tackle flood risk and will not be used in isolation. Please refer to the SEPA website for more information on natur

Use our flood maps to check flooding risks in your area or anywhere in Scotland. THIS CONTENT HAS BEEN MOVED TO BETA Flood maps Our flood maps are designed to help you understand how you could be affected by flooding. The maps show you areas which are likely to flood from rivers, the sea and surface water. The flood maps are a public tool and used by a wide variety of people for a range of work. We currently have two map viewers available. To determine which viewer will benefi
