  1. CUAHSI In EthiOpia :First Implementation and perspectiveS Xavier Thomas - BRLi TesfayeAbebe : Project manager - MoWR of Ethiopia Fang Zhong-Xue - BRLi CUAHSI Conference 2013, Logan, 07/19/13

  2. Tana Beles Water Integrated Resource Development Project • The largestlake in Ethiopia (Area : 3150 sq. km, Basin : 150000 sq. km) • The source of the Blue Nile • A growth corridor • Total cost : 70M$ • funded by WB :45M$, GoF:7.25M$, GoE : 17$M • HIS implementationrun by companies : BRLi (France), Halcrow (GB), Géo-Hyd (France), Omega (Ethiopia)

  3. HIS implementation : Needsanalysis • Thinkbig, startsmall : Tana Beles IS is a « template », must bedeployed to the others basins • Water management willrespond to a distributedorganization, not centralized : More responsabilitiesat basin level,data collection, data validation, dissemination and decisionmaking • A lowcost of implementationisexpected • based on International standards data exchange • Data dissemination to stakeholders and partially to general public

  4. Why CUAHSI (the pros and cons) Pros Cons • An open source : • Available software • Reuseexisting code • Module extension model of hydrodesktop • A simple database model able to store WQ, Hydrometric and meteorologic data • Adocumentedsemantic • A shared variable repository • A unique way to access multiple databaseslocatedatdifferent places: • Water One Flow Web Service • Data transmitted in WaterML XML format (OGC standard) • A unique semanticmanaged by Update Controlledvocabularymecanism • Neededmissingfunctionalities : • gap filling, • rating curves management • Needs a reliable communication network betweenorganizations and general public

  5. Data collection :Teletransmission, observers, laboratory,… Existing datasets :Stakeholders Databases,Historical dataset Modeling activities ODM1.1 extended Interpreted DataDerived ProductKnowledge product Unknown, qualitycontrolled Read only data set Addedentitiesmatch project requirements ODM 1.1 Draft Data validation Raw QualityControlled Gauging Source QualityControlled Site Rating Variable Dissemination Role Unit Read only data set Values User Quality Control level

  6. The data management tools StakeholdersDatasets Data Converter Data Capture ODM file ODM ODM streaming data loader Data Capture Template editor Data Expert Time series management, gap filling, validation, rating curves, derivation,…

  7. ABA Information system (nextstep) • Web site implemented with the Content Management Software DotNetNuke • Contents of web pages can be updated by a non Programmerspecialist • A Web portal gathering time series and spatial data : reports, analysis, maps,yearbooks, etc. • Search capabilities based on documents indexation by keywords (DNN module from the market) • Embed HydroServerTSA as a DNN module • Use of DNN user rights management system (Access to HydroServerTSA module)

  8. Sensitive Time Series Data protection Attributeadded to match data protection requirements ODM 1.1 Times seriescatalog Sensitive series Web portal (Protectedaccess) Web portal (Public access) Water One Flow WS

  9. Main Conclusions • This projectintroduces CUAHSI Data model in Ethiopia and provides data management tools • The added value of CUAHSI willbeobtainedwhenitwillbedeployedto the othersbasins : • Data sharing, use of hydrodesktop • Use of a controlledvocabularyat National level
