Western Catchment Flood Risk Assessment and Management Plan (Western CFRAM), Ireland

JBA Consulting

The project, over 8 years, included a number of stages: management of survey contracts; hydrological

analysis and flood modelling; risk assessment and options development; strategic environmental

assessment; climate change assessment; and production of the flood risk management plan and

consultation.

Challenge

We were commissioned to develop flood hazard and risk maps and the flood risk management

plan for the Western River Basin District, for the first cycle of the Floods Directive.

Western Catchment Flood Risk Assessment and Management Plan (Western

CFRAM), Ireland

Location: Ireland Client: Office of Public Works

Solution

To deliver this project we managed large scale river survey contracts, we undertook hydrological

assessment of gauges, we regionalised estimates of flood flows, we assessed flood risk through

detailed 1D/2D hydraulic models and we prepared detailed flood mapping including flood extent,

probability and its consequences.

This led to the development and appraisal of options to manage the flood risk, including both structural

and non-structural measures. Throughout the project a number of consultation events were held and

driven by our team.

Benefit

The resulting flood risk management plans have enabled the Irish Government to prioritise and

progress the development of flood relief schemes and minor works schemes in the west of Ireland.
