Our challenge • By 2025, 1.8 billion people will live where water is scarce • Water is fundamental to health, nutrition and energy • Water security is a pressing concern due to population Water security is a pressing concern due to population growth, climate change and drought • The threat of flooding in both vulnerable and established • The threat of flooding in both vulnerable and established communities is increasing • Water is a power source that is not yet being properly exploited. Water is a power source that is not yet being properly exploited 2

Dealing with flooding Mike Woolgar , Managing director, Environmental and Water Management g g , g 3 November 2011
Agenda • What are the effects of flooding? • Why is it happening? • Why is it happening? • How can we deal with it? 11
Flooding Recent flood events have had devastating impacts all had devastating impacts all over the world 12
Why floods matter Death Despair Despair Raft of devastating social and economic Damage Damage impacts Dereliction Dereliction Decay Decay 13
Thai floods - 2011 Infrastructure & workforce Stocks fall -Thai economy impacted suffers double whammy Severe Flooding – 300 people killed Worldwide rice supplies 1000 factories inundated are threatened International technology companies face shortage of hard drives 14
Floods - types • River flooding • Coastal/sea flooding • Coastal/sea flooding • Surface water flooding. 15

Why are floods more visible? • 70% of world’s populations already live in areas at risk of flooding 70% of world s populations already live in areas at risk of flooding …Urban developments are frequently on rivers or by the sea for historical reasons . • ‘Business as usual’ means that we are building more and more in these locations …which by itself increases risk… hi h b it lf i i k • Add climate change risk • Add climate change risk …rising sea levels, increased storminess and higher intensity rainfall = even more risk. • So, more stuff to be damaged + increasing likelihood = a double hit! • Social commentary post-Pitt has raised awareness …But Nature Check (October 2011) said government “failing” to implement ( ) g g Pitt Review. 17
What should we do? • Planning must take place at a landscape or catchment level to understand the many interactions y • In a more tightly-packed world decisions are more complex and need multi-disciplined response • Systems approach is needed We live in a world where food, water supplies, roads, power (etc) are interlinked i t li k d Systems approach to urban management to ensure the close interdependencies of water and economics are: fully understood – and decisions are made in the interests of resilience. – 18
Flooding around the world • Flood risk management around the world has different drivers and faces different challenges • Case studies: • UK • Africa • Middle East. 19
UK Shaldon Shaldon • Low lying ground and ‘basin’ caused serious flood risk • 1.7km of tidal defence protection 1 7k f tid l d f t ti • Atkins designed and project managed flood defence scheme • Extensive consultation with the local community • Protection to 453 properties against a 1 in 1,000 chance of flooding • Other environmental improvements. Teignmouth Teignmouth • Design of Teignmouth flood defences awarded to Atkins due to excellent work at Shaldon • £4 £4m scheme will reduce flood risk to over h ill d fl d i k t 400 properties. 20
UK Severn estuary flood risk management strategy • 300km of coastline, 200,000 residents and £14bn of infrastructure • Unique and internationally designated Unique and internationally designated environment • Atkins is producing this long term plan for management of flood and coastal risk management of flood and coastal risk - in light of climate change - achieving UK and European legal req irements for managing habitat requirements for managing habitat - building robustness into the plan due to longer term uncertainties. 21
Africa Malawi – Shire River • World Bank project to carry out an integrated World Bank project to carry out an integrated flood risk management plan for the Shire Valley in Malawi • Country’s main source of water for food Country s main source of water for food crops, industry, water supply and hydro- electric power • Atkins investigating resilience of existing Atkins investigating resilience of existing infrastructure and the institutional framework • Team is preparing recommendations to strengthen flood risk management and strengthen flood risk management and protect a fragile but developing economy • Builds on our water resource management work to examine economic management work to examine economic development paths. 22
Africa Nzoia River, Kenya • World Bank funded flood protection project along 40km reach of river project along 40km reach of river • Existing embankments have been failing with increasing frequency since 1997 • C Crops and homes are destroyed and d h d t d d 7,000 people (many subsistence farmers) are displaced when embankments breached breached • The area is one of the poorest in Kenya, largely as a result of the regular inundation inundation • Atkins is assessing flooding issues in the downstream section of the catchment, evaluating management options and evaluating management options and providing detailed design for the proposed approach. 23
Middle East Wadi Hilti-Salahi Flood Protection Dams – Oman • Flooding in Muscat and surrounding area caused by Gonu cyclone in 2007 • • Atkins has been contracted to carry out Atkins has been contracted to carry out a feasibility study, detail design and construction supervision of flood retention dams • Protection provided against floods up to 1,000 year return period • • Delicate environment and archaeological Delicate environment and archaeological sites. 24
