Tidal resource assessment is presented for Rathlin Sound, located between Rathlin Island
and the north-east coast of Northern Ireland. The flow is simulated in 2D, using the shallow
water equations. For an M 2 tide, the natural flow conditions exhibit local spatial mean and
maximum flow speeds of 2 and 3 m/s. Upper limits to power extraction are about 298 MW for
M 2 and 330 MW for M 2+ S 2 tidal signals (different to undisturbed kinetic power and power
naturally dissipated at the seabed). An analytical model of a channel connecting two infinite …

abstract Tidal resource assessment is presented for Rathlin Sound, located between Rathlin
Island and the northeast coast of Northern Ireland. The flow is simulated in 2D, using the
shallow water equations. For an M2 tide, the natural flow conditions exhibit local spatial
