SHANNON ESTUARY BARRAGE
Note added 24.10.20
​
A Shannon Estuary Barrage can take a multiplicity of forms and be used for a multiplicity of purposes.
Primary Function are listed under the following headings:
​
-
Surge Tide Flood Control
-
Fresh Water Conservation
-
Hydro Power
-
Inland Waterway Network via a sea lock

HYDRO POWER
The Concept
Ross's Tidal Barrage Hydro Power Concept, exploits both Shannon Estuary tidal water and Shannon river water flowing into a Containment Lake.
Generating capacity is estimated at circa 200 MW.
(See Swansea Lagoon Project as an example of tidal hydro).
​
Calculations are based on the following:
​
The Containment Lake extends circa 11km from Thomond Bridge, Limerick, to the Barrage.
Estimated capacity of the Containment Lake = 18 million cubic metres.
Average river flow at Thomond Bridge is 208 cumecs per second = 18 million cubic metres per day
Tidal range at Limerick Docks = 5.44m. Highest recorded tide = 8,5m
Tides Incoming ( 2 tides every 24hours 50 minutes). Tidal flow average per day = 22 million cubic metres.
Total of outgoing Tides + river flow volume = 40 million cubic metres/day.
