  2. Content • Why this knowledge program? • Objectives • Alignment with other programs

  3. 1. Why this program? Situation after 2012 Water supply in rural areas Remco van Ek (BGS) River basin management Rinus Vis (VEB) Fresh Water supply in urbanizing Deltas Remco van Ek (BGS) Beschikbaarheid Water en Grondstoffen Jaap Kwadijk (MT, ZWS) Ipo Ritsema (MT, GEO) Marc Bierkens (WR, BGS) Rinus Vis (VEB) (ondersteuning) Urban water supply Hans Gehrels / Frans vd Ven (BGS) Sustainable energy from water and subsoil Ivo Pothof (HYE) Visualization and characterization of the Subsoil Bob Hoogendoorn (BGS)

  4. 1. Why this program? Especially developing countries! More and more people, and more and more in cities! Global water demand: baseline scenario • 2000 • Irrigation is 67% of total • 2050 • Irrigation is 40% of total. • Water demand for manufacturing will increase x5

  5. 1. Why this program? Water Stress Index 2011, Maplecroft Overexploitation of groundwater resources, Gleeson et al, 2012

  6. 1. Why this program? No problem! We have more than enough water.

  7. 1. Why this program? Total water volume All fresh water All lakes, rivers All water Fresh water is a scarce resource

  8. 1. Why this program? Some numbers… • Total water volume (Oceans & Fresh water): 1.338.000.000 km3 • Fresh water (Frozen, groundwater, lakes & rivers): 40.140.000 km3 • * Groundwater: 10.530.600 km3 • * Lakes & Rivers: 104.590 km3 • IJsselmeer (total) 4.8 km3 • Zoet grondwater 1.100 km3

  9. 1. Why this program? Effect of Climatechange Droughtincrease (Dai, 2011) PDSI Palmer Drought Severity Index Normal [-0.5, 0.5] Mild drought < -1 Moderate drought < -2 Severe drought < -3 Extreme drought < -4 Dry becomes drier, Wet becomes wetter

  10. 2. Objectives • Fresh water supply in urbanizing deltas • Urban: Develop knowledge and tools that enable sufficient water of good quality for economic development and living conditions in urban delta areas • Linkage of urban and rural water supply, linkage delta-, agro, watertechnology • Subjects • Urban: Resource management, resource use efficiency, coupling water cycle with water system, water for cooling and greening, self sustaining cities, groundwater management. • Focus: international market. Delta metropolitan areas like Singapore, Shanghai, London, Jakarta, Randstad

  11. 2. Objectives

  12. 2. Objectives • Activities so far… • Reconnaissance NL:options for sustainable urban water supply in Deltaprogram(DP N&H + DP ZWV: VerkenningWaterbehoefte en -voorzieningstad) Eerste orientatie gestart met focus op duurzame watervoorziening stad

  13. 2. Objectives Reconnaissance for international market: • Inventory of character and size of problems with urban water supply in various cities around the world • Capability statement with portfolio en future plans • Picture all available water resources • Rainwater, groundwater, surface water, sewer water (grey water), seawater … • Quantify urban water use • Domestic water (drinking, sanitation), industrial water, water for energy production, recreation, urban blue/green infrastructure, biodiversity, water for cooling, water to prevent land subsidence and protect infrastructure/foundation. • Possibilities to reduce water demand / net demand • Closing the water cycle (closed cities), reduce, reuse water for functions • Develop tools / instruments for assessment, prediction and scenario analysis • Besides technology also focus on linkage with water governance • Build innovative showcases: urban fresh water supply

  14. 2. Objectives • Knowledgeproducts • Living labs (proeftuinen) forurban water supply • New approaches for sustainable strategies, innovative measures • Database? What is possible in what kind of situation? Impact? Cost? • Bringknowledgeintopractice (proof of concept) • For example • -“Watervoorziening Utrecht (Citychlor)” • - “Watervisie Uithof” Concept www.usi-urban.nl

  15. 2. Objectives • Knowledge products • Concepts, tools and instruments • Rapid Assessment Model for urban water supply in data scarce areas(assessment, prediction and scenario analysis) • Linkage with Open Streams • Makes use of RS data, additional free data and optional data collected through QS field reconnaissance (role of TGG?) • Map tables tools for data rich areas (3Di, Hydrocity?) • Research plan 2013:deliver prototype instrument thatallowsquantification of water supply and water distribution Concept

  16. 3. Alignment with other programs • Cooperation • NWO Urbanizing deltas (Bierkens/Rijnaarts) • Topsector water, SKIA’s • Duurzamedeltasteden, Proeftuinen NL, Digitale Delta • Deltaprogramma? • Internal alignment • “Open Streams” (VEB, DSC, ZWS/BGS) • Knowledge programs (Rinus, Ivo, Bob, Marco, Ad, …) • CIP / USI / UU • Desires of heads of Deltares departments / market development • External alignment • Consultants • Governmental programs

  17. 3. Alignment with other programs • Requirements for projects with SO funding • Project contributes to program objectives • A “plus” if • Good external matching • linkage between urban and rural • cooperation of several units (VEB, ZWS, BGS, DSC) • link deltatechnology with water- and agrotechnology • direct linkage with Topsector water • International R&D project

  18. "water city" concept, Ayutthaya, Thailand

  19. Fresh water supply in urbanizing deltas Global view on overexploitation of groundwater resources

  20. 2. Objectives • Fresh water supply in urbanizing deltas • Urban: Develop knowledge and tools to enable sufficient water of good quality for economic development and living conditions in urban delta areas • Rural: Develop knowledge and tools to enable sufficient water for food production and natural ecosystems. • Linkage of urban and rural water supply, linkage delta-, agro, watertechnology • Issues • Urban: Resource management, resource use efficiency, coupling water cycle with water system, water for cooling and greening. Closed city, groundwater management. • Rural: Water conservation, reservoir management (above and below ground) in relation to land use (e.g. agriculture, nature) • Focus: international market. Delta metropolitan areas like Singapore, Shanghai, London, Jakarta, Randstad

  21. Watervoorziening/benutting in de stad Speerpunt oude roadmap: Klimaatbestendig maken van steden • (Urban Flooding) • Hittestress – kwantificeren verkoeling door water en vegetatie • Stedelijke waterschaarste – droogteschade stad (fundering) • Kennis voor Klimaat Tranche 1 projecten voor Rotterdam en Haaglanden • Probleemanalyse, adaptatiemogelijkheden buitendijks, hittestress Tranche 2 Climate Proof Cities • Metingen Water & Hitte in de stad • Schadegevoeligheid stad voor wateroverlast en droogte Tranche 3 Waterbehoefte en watervoorziening steden • Offerte studie Waterbehoefte stad
