Forres Flood Alleviation Scheme – Chapelton Dam

Forres Flood Alleviation Scheme – Chapelton Dam

After severe flooding in 1997 and 2000 when the Burn of Mosset inundated homes & businesses in the centre of Forres, The Moray Council appointed Royal Haskoning to find a sustainable solution to alleviate flooding in Forres, as well as nearby Lhanbryde and Elgin.

Forres Flood Alleviation Scheme – Chapelton Dam

Chapelton Dam is the main part of the scheme and its purpose is to restrict the peak flow of water passing through Forres during flood events.
The Dam’s spillway was protected with a 400mm thick layer of OSA placed on a coarse aggregate filter layer and geotextile. Over 3,500m2 was placed in 3 weeks and the whole downstream face was top-soiled and grassed so despite the buried engineering the surface looks natural.
