Courtesy of Arnold HornerMany of the longer Irish rivers flow, for at least part of their journey to the sea, along courses where the gradient is quite limited. As a result, they are quite sluggish. When there is prolonged rainfall in their upper reaches, they may overflow downstream, flooding adjacent areas. The longest Irish river is the Shannon, which rises on Cuilcagh mountain, Co. Cavan. With its tributaries, notably the Rivers Suck, Inny and Brosna, and the Rivers Fergus and Maigue, which flow into its estuary, it drains over 15700 square kilometres of central Ireland. Its total length is 360.5km including some 102.2 km of tidal water.
Over its first ten kilometres to Lough Allen, the Shannon descends some 500 metres, but along a middle section of some 120km, between Lough Boderg and Lough Derg, the river falls less than nine metres, while at the same time receiving the input of the Suck, Inny and Brosna. Not surprisingly, perhaps this part of the Shannon, which includes the famous Shannon Callows, south of Athlone, and the ancient monastic site of Clonmacnoise, is liable to serious winter flooding, on a scale which so far has proven difficult to control.
