energy - particularly in India and China
Tidal energy generation has advantage over
wind and waves - tides are predictable
UK target of generating ≥ 20% of electricity
from renewable resources by 2020
Wales’ 2025 target for marine renewables is
14 TWh/yr - Barrage could generate 65%
Severn Estuary basin is ideal for tidal energy

EIA Studies for All Impoundments
(Courtesy of Prof RA Falconer)
Computer models used to predict changes to:􀂾Tidal currents – speed, levels, eddies, river plumes
􀂾Wave climate – height, length, refraction,
reflection
􀂾Suspended sediment – distribution along channels
􀂾Sediment deposition – in and out of impoundment
􀂾Coastal morphology – changes to beach profiles
􀂾Water quality – turbidity, bacteria, light
penetration
􀂾Pre-/post-construction – short & long term
impacts
􀂾Mitigating measures – changes to
design/operation

Main Effects of Barrage
• Spring tide range reduced from 14 m to 7 m
􀂾 Significant loss of upstream inter-tidal habitats
􀂾 Reduced tidal currents upstream of barrage
􀂾 Reduced suspended sediment levels upstream
􀂾 Increased light penetration in water column
􀂾 Increased dissolved oxygen concentrations
􀂾 Increased primary productivity and changed
bio-diversity of benthic fauna
• Upstream tidal range of 7m is comparable to
other UK estuaries, e.g. Thames & Humber
