2 ‘CFRAM’ STUDIES ‘CFRAM’ PROGRAMME
Outcome of National Flood Policy Review, 2004 Compatible with FD Requirements, 2007 Flood Maps FRMPs Pilot Studies: Lee, Dodder, Fingal – East Meath: National Programme: Focused on 300 Communities (‘AFAs’)

3 300 ‘AFAs’

4 SCOPE OF WORK Survey & Data Collection Hydrology Hydraulic Modelling
Appx. 6,500kms River Channel Hydrology Incl. Use of FSU Hydraulic Modelling 1D-2D Dynamically Linked Models Flood Mapping Extent, Depth, Velocity, ‘Risk-to-People’, Flood Zone & Various Risk Maps

8 ‘CFRAM’ STUDIES FLOOD MAPS (‘CFRAM’ PROGRAMME)
Range of Flood Maps Produced Extent, Depth, Velocity, ‘Risk-to-Life’, Flood Zone & Various Risk Maps Up to 8 Flood Event Probabilities Future Scenario Mapping 2 Representative Climate Futures MRFS: +500mm MSL, +20% Qp HEFS: +1000mm MSL, +30% Qp

9 FLOOD MAPS Detailed Mapping for 300 Communities
Incl. 90 Coastal Communities Communities with Appx. 3m People (Appx. 2/3rds Population) Less Detailed Mapping for Appx. 2,500 km Other River Inform: Sustainable Planning Emergency Response Planning Community Resilience

10 ‘CFRAM’ STUDIES FRMPs – COMMUNITY-LEVEL MEASURES

11 ‘CFRAM’ STUDIES FRMPs – COMMUNITY-LEVEL MEASURES
Screening & Option Development Options Developed to ‘Line-&-Level’ & Costed Appraisal Multi-Criteria Analysis (MCA) Cost-Benefit Analysis (CBA) SEA / AA Environmental Assessment Adaptability to Climate Change Public Consultation: Over 450 PCDs

12 ‘CFRAM’ STUDIES FRMPs – COMMUNITY-LEVEL MEASURES
Overall FRS Programme (Protection) 43 Schemes Completed 35 Schemes in Construction, Design, Planning 118 Further Schemes Proposed in FRMPs Protection for Appx. 33,000 Properties: Appx. 95% Properties at Risk in AFAs Appx. 80% Properties at Risk Nationally

13 ‘CFRAM’ STUDIES FRMPs – NATIONWIDE MEASURES Prevention:
Sustainable Planning & Devt. Management Sustainable Planning Critical for Sustainable FRM Guidelines: The Planning System and Flood Risk Management (OPW/DECLG, 2009) Supported by OPW Advice & Flood Mapping

22 FUTURE WORK CAPITAL FLOOD RELIEF PRPOGRAMME Government Commitment
Budgets Allocation of Circa €1bn (NDP ) Annual Budget to Increase to €100m/yr 10 Schemes in Construction, 25 in Design / Planning Almost 120 Additional Schemes – FRMPs Prioritisation – Appx. 50 ‘Tranche 1’ Schemes Progressing to Project-Level Assessment Generally Local Authority Lead; Part X Thanks for opportunity Presentation take about minutes Followed by Q&A Feel free to stop me at anytime Handout of presentation available

23 FUTURE WORK ADAPTATION TO CLIMATE CHANGE The ‘CFRAM’ Programme
Future Scenario Flood Mapping / Risk Assessment Assessment of Adaptability of Options National Future Scenario Flood Mapping Adaptation in Flood Relief Schemes Adaptability of Past Flood Relief Schemes Apply Managed Adaptive Approach Scheme Adaptation Plans Update Sectoral Adaptation Plan: Sept. 2019 Thanks for opportunity Presentation take about minutes Followed by Q&A Feel free to stop me at anytime Handout of presentation available

24 FUTURE WORK NATURAL WATER RETENTION MEASURES
Emerging Approach often Promoted Detailed Assessment at Project Scale Concerns / Issues to Address: Difficulty in Quantifying Projected Benefits Effectiveness in Large Events Intensive Land Owner Engagement Benefits to Other Sectors: Integrated Catchment Mgt. Research / Pilot Projects Thanks for opportunity Presentation take about minutes Followed by Q&A Feel free to stop me at anytime Handout of presentation available

25 FUTURE WORK PREVENTION AND PREPAREDNESS Flood Forecasting and Warning
National Flood Forecasting Service in Development Emergency Response & Community Resilience Review of Emergency Response Plans, Informed by CFRAM Maps Enhance Community Resilience Property Resilience Home Relocation Scheme Pilot ‘IPP’ Schemes Thanks for opportunity Presentation take about minutes Followed by Q&A Feel free to stop me at anytime Handout of presentation available

26 FUTURE WORK SECOND CYCLE OF FLOODS DIRECTIVE
Review of PFRA, Flood Maps, FRMPs Review, Not a ‘Re-Do’ Opportunities for Refinement / Improvement Consideration of Climate Change Scope (AFAs): 1st Cycle Relatively Low Threshold of Risk (Recent Floods) Comprehensive Coverage of Communities 2nd Cycle No Need to Replicate CFRAM Programme Focus on Understanding Risk in Rural Areas

27 FUTURE WORK SECOND CYCLE OF FLOODS DIRECTIVE Sources: Impacts:
New National, Indicative Fluvial Mapping Review Extreme Coastal Levels Groundwater / Turlough Mapping Risk from Urban-Storm Water Systems / Artifical Water-Bearing Infrastructure Impacts: Understanding Rural Risk Critical Infrastructure Impacts of Climate Change

28 FUTURE WORK SECOND CYCLE OF FLOODS DIRECTIVE PFRA: Flood Maps:
Historic Flood Information (Floods 2012-Date) Predictive Assessment of Risk (Incl. CFRAM Data) Local and Expert Knowledge Flood Maps: Ongoing Changes (Infrastructure, Floods) Need to Reflect Changes in Timely Manner Flood Risk Management Plans: Review of Progress on 1st Cycle FRMP Measures Additional / Amended Measures

29 SUMMARY CFRAM – EVOLUNTIONARY STEP FORWARD: PROTECTION:
Assessment Covering 3m People (2/3rds National Population) 2nd Cycle: Review, Refine and Improve PROTECTION: >150 Schemes In-Hand / Proposed in FRMPs Broadening Approach: NWRM / ICM Ensuring Adaptability to Future Climate PREVENTION & PREPAREDNESS: Sustainable Planning & Development National Flood Forecasting Centre Community Resilience Thanks for opportunity Presentation take about minutes Followed by Q&A Feel free to stop me at anytime Handout of presentation available
