Catchment Management

Scotland’s contribution to international water policy and research (Report)

On World Water Day in 2018, we held a workshop exploring Scotland’s contribution to international water policy development and research needs. This workshop brought together Scottish academics, practitioners and policy makers to share experiences in promoting the UN Sustainable Development Goal: “ensure availability and sustainable management of water and sanitation for all” (SDG 6).

The use of remote sensing to detect and monitor algal and cyanobacterial blooms

At a UK and European level there is currently no suitable way to measure the frequency and intensity of algal blooms. One of the major stumbling blocks is the cost involved in undertaking sufficient sampling (and counting) of the frequency of algal blooms at a large number of sites. Additionally, a single sample may not be representative of an algal bloom, in particular cyanobacterial blooms, which can form surface scums and be blown towards lake shorelines. The use of satellite remote sensing can overcome some of these problems.

Investigation of the relationship between humic substances and total phosphorus and the processes of release from catchment soils to loch waters

This study outlines proposals to clarify the importance of water colour (in terms of dissolved organic matter - DOM - compositional quality, e.g. humic substances (HS) content) for predicting TP concentrations in Scottish Lochs to help meet regulatory criteria under the Water Framework Directive. 

What evidence does SEPA need to deliver RMBP objectives for 2027 for rural diffuse pollution pressures?

Rural diffuse pollution is the main cause of downgrades to the water quality of Scotland.  The objective for this workshop was to confirm the evidence gaps in our understanding of rural diffuse pollution, which are hindering the delivery of the ambitious RBMP improvement objectives set for 2027.

Experts attended the workshop to help SEPA understand the state-of-knowledge and determine what the priorities should be for research and evidence gathering for the next six years.

World Water Day - 22 March

Every year World Water Day is celebrated on 22nd March. This year the theme is 'Nature for Water' with events being held worldwide. The theme is encouraging nature-based solutions to the problems that we currently face, like floods, droughts, and pollution. Check out more at the World Water Day website.

Factoring Ecological Significance of Sources into Phosphorus Source Apportionment

Models describing the relative contributions of phosphorus (P) from different sources to water bodies (source apportionment) are key tools in determining priorities for mitigation strategies within the River Basin Management Planning process under the Water Framework Directive (WFD). Previous source apportionment was simplistic because it was based on total P loads, even though not all P loading has the same ecological significance due to the form or timing of the loading.

How do we increase public understanding of the benefits provided by SuDS?

There is a need to increase awareness of the benefits that water provides and how our actions can help protect and improve them. Concerns over water quality and quantity are increasing around the world and these are exacerbated by climate change and other pressures. Arguably, and having a plentiful supply of water from rainfall, Scotland has not been severely affected by these issues. Consequently there is a perception that public understanding of water and the benefits provided is often low.
