Continuous monitoring equipment has been deployed from a buoy in the upper Forth estuary near South Alloa since 1988 to monitor dissolved oxygen, salinity, temperature and turbidity. Dissolved oxygen is consumed by the decomposition of organic matter. Organic matter in the upper Forth estuary originates from discharges of organic waste and organic rich sediments mixed into the water column as a re

Likelihood of Flooding The chance of flooding occurring. You can select to see information for three flooding likelihoods: High, medium and low.High likelihood: A flood event is likely to occur in the defined area on average once in every ten years (1:10). Or a 10% chance of happening in any one year. Medium likelihood: A flood event is likely to occur in the defined on average once in every two h

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

A full list of RBMP publications. This page provides a full list of RBMP data sources. Water environment hub The tool provides information on current condition and future targets for rivers, lochs, coastal waters and groundwaters. Classification information The most detailed and up to date classification information for all parameters is available in our water classification hub. This has maps of all results, along wit

The majority of dams will require an authorisation from SEPA under "The Water Environment (Controlled Activities)(Scotland) Regulations 2011 (CAR). This authorisation number will start CAR/.../... If you don't have a CAR authorisation for your dam, then you should contact your local SEPA team to discuss this. You can find more advice on impoundments and water resources authorisations on our Enviro

Frequently asked questions Why is a sea lice framework needed? Populations of wild Atlantic salmon have been in serious decline in recent decades and are now at crisis point. The pattern of decline is repeated across the salmon’s North Atlantic range and is likely caused, at least in part, by the effect of climate change on the survival of salmon during their time at sea. To build resilience of Sc

What is an elevated building? A building where structures such as pillars or stilts are used to raise it above the expected flood water level. The ground below the building remains at risk of flooding and allows for the free flow of water. Context for this position statement This position statement constitutes part of ‘relevant SEPA advice’ as referred to in criterion a) iv of the National Plannin

Further technical guidance This page brings together a number of ancillary guidance documents and previous email bulletin information relating to modelling of marine fish-farms for CAR licence applications.
