Models of Dam Spillways
Dam spillways are constructed from timber, plastic and GRP. Usually a representaive section of ground surface is constructed to gauge the likely effect of overspill from the reservoir spillway. Scales typically range from 1:20 to 1:25, and models would be tested for:
- Stage discharge of weir/spillway top end
- Overspill from channel
- Stilling at the bottom of spillway
Ray Baker, who has special responsibility within the company for spillway modelling is a long term member of the BDS, and has over 25 years experience in testing spillway models.
We aim to use our experience of spillway modelling to try to build as many potential modifications as possible to reduce the time and expense to the client if the spillway does not pass PMF.
