The British Dam Society
The BDS provides technical subjects relating to the planning, design, construction, maintenance, operation, safety, social and environmental aspects of dams and reservoirs.
Maintaining healthy grass cover is necessary for safeguarding the resilience of embankment dams and levees and is critical if they are designed to overflow.
Grass will tolerate a range of operational stresses ranging from drought to saturated ground if:
The use of standard ‘grass only’ mixes, is likely to lead to disappointment if it is unsuited to the local site conditions and not measured against a sufficiently robust specification.
The presentation will draw on the contents of a paper, jointly written by Mike Hughes (Atkins) and David Holland (Salix River & Wetland Services Limited), published in the Proceedings of the 21st Biennial Conference of the British Dam Society held at Nottingham University from 15 to 17 September 2022.
The presentation will provide a practitioner’s viewpoint on the importance of grass cover and explore a number of current industry publications and specifications to provide recommendations for more easily enforceable definitions of what acceptable grass cover is. The presentation will also question the standardised approach of specifying grass only seed mixes, and whether more diverse seed mixes including a small percentage of appropriately selected herbs or legumes may instead be beneficial and whether resilience can be improved by selection based on observations of existing grass diversity in the embankment and adjacent areas.
In this Yorkshire and Humber knowledge sharing session, a broad overview will be covered on the use of laser scanning and how the benefits of this can be used to aid in project design, delivery and improve efficiency.
