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.
