Eleven areas throughout the county will come under the spotlight this week.
The work will rely on the public to help determine potential hazards, so the Council can identify measures to manage the risks and prepare a strategic flood risk management plan to deal with the problem areas.
Two public consultation days have been organised.
The meeting for flood issues affecting Ardara, Bundoran, Donegal Town and Killybegs will be held this Wednesday between 3pm and 7pm in the Donegal Public Service Centre, Donegal Town.
A separate meeting for the Ballybofey-Stranorlar area will also take place between 3pm and 7pm on the same day but at the Villa Rose Hotel in Ballybofey.
Consultations will continue the following day, Thursday, March 26 between 3pm and 7pm at the Old Courthouse, The Diamond, Lifford for the Castlefin, Convoy, Killygordon and Lifford areas.
The Letterkenny Public Services Centre on the Neil T Blaney Road will be the venue for consultations for those affected by any flooding issues in the Letterkenny and Newtowncunningham areas. This also takes place between 3pm and 7pm on Thursday 26 March.
