MEETING OF SOUTH DUBLIN COUNTY COUNCIL

Monday, October 08, 2007

QUESTION NO. 5

QUESTION: Councillor J. Lahart

To ask the Manager to outline whether there is a recognised pattern of flooding in the county or whether or not such a pattern is being monitored by the Council or any other body?

REPLY:

The most obvious pattern of flooding relates to low lying areas near rivers and streams. The river response to a particular rainfall event depends on the size, impermeability and slope of the catchment.

Some rivers such as Liffey are responsive to long duration rainfall while others such as the Dodder are responsive to short intense rainfall events.

The Council records flood levels where possible.
