2 1. SUMMARY EU FLOOD DIRECTIVE EMERGENCY PLANS NATIONAL DIRECTIVE

3 2. CONCEPTS: FLOOD CHEIA Extreme hydrological phenomenon, with changeable frequency, natural or induced by human action, which consists in the overflow of a water course, originating flooding in marginal lands. FLOOD INUNDAÇÃO Extreme hydrological phenomenon, with changeable frequency, natural or induced by human action, which usually consists in a submersion area.

4 2. CONCEPTS: RISK MATERIAL DAMAGE AND ECONOMIC DISRUPTION SOCIAL WELL- BEING NATURE CONSERVATIO N PROJECT FUNDING AND NATIONAL PRIORITIES RISK PROTECTION OF LIFE SAFETY SUSTAINABILI TY

5 2. CONCEPTS: FLOOD RISK

6 2. CONCEPTS: FLOOD RISK Flood Hazard Intensity Probablity Frequency Exposition of vulnerable elements to the phenomenon RISK FLOOD RISK HAZARD EXPOSURE Vulnerability of the elements to the phenomenon Damages from the flood impact VULNERABIL ITY

7 3. METHODOLOGY ANALISYS VULNERABILITY ADAPTATION Hydrographic Basin Plan Lis River Social and biophysical characteristics Identified interventions and problems Historical flood registers Flood area Municipal Land Use + RiproCity Project Use + RiproCity Land use in flood area Urbanized territory Agricultural and agro-forest areas Natural and halfnatural forest Fragilities EU Floods Directive Exposure Population affected Economic activities affected Activities that can cause pollution Sensible and vulnerable zones affectedd Cultural patrimony affected Impacts Risk perceptio n RECOMMENDATIONS/SUSTAINABILI TY (?)

8 3. CASE STUDY: LIS RIVER Oceano Atlântic o The Lis river basin is situated in the region center of Portugal, demarcated by Mondego River Basin (North) and Tagus River Basin (South) Rio de Fora Ribª dos Milagres Rio Lena Ribª do Sirol Rio Lis Rio Alcaide

9 3. CASE STUDY: LIS RIVER LEIRIAPOLIS The Lis river as principal subject

10 3. CASE STUDY: LIS RIVER LAND USE (Flood area) (hect) Urbanized area 2,3 Florest and natural areas 1,3 Agriculture and/with florest 0,9 Watercourse 0,2 TOTAL 4,7

11 3. CASE STUDY: LIS RIVER Some exposure elements in flood area (LEIRIAPOLIS) Efforts needed to reduce the flood risk

12 3. CASE STUDY: LIS RIVER EXPOSURE INDICATORS LOW MEDIUM HIGH 1 People affectad < > Economic activities Agriculture 1 Agriculture 2 Agriculture, 3 affected 3 Acidental poluttion 1 and service 2 service and industry 3 provocqued by flood 4 Protected zonas affected MN, PP, SC 1 PN, RN, ZPE, 2 RMRB, PNAC 3 5 Patrimony affected IIM 1 SC IIP 2 PM, MN 3 6 Sensible zones extension (91/676/CEE Directive) 7 Vulnerable zones extension (91/271/CEE Directive) FINAL EVALUATION EXPOSURE LOW Under < 8 and MEDIUM 14 HIGH > 14

13 4. ROAD TO FLOOD RISK SUSTAINABILITY (?) Survive and prosper in the face of major natural events Reduce vulnerability of people and property FLOOD RISK SUSTAINABILI TY Sustainable does not, however, necessarily mean that all risk is eliminated Emergency Plans for high-risk areas Disaster-resistant communities
