  1. HYDROLOGICAL ANALYSIS Date of mission: 9th – 28th of June 2008 Basin hydrologist - ZX. FANG from BRL ingénierie

  2. OBJECTIVES • Data gathering and processing • Hydro-statistics • Scope of the work for next steps of the project

  3. DATA GATHERING AND PROCESSING • Existing studies /documents • Types of needed data • River data: hourly, daily, monthly and annual flows • Rainfall • Climatic data • Geomorphological data – land cover

  4. DAILY FLOW

  5. MONTHLY FLOW

  6. GAP FILLING & DATA VALIDATION

  7. REFERENCE PERIODE FOR FLOW DATA • Times series terminated in 1986, no recent flow data • Reference period 1952-1986 for monthly flow (Qm) • Daily flow (Qd): less data than QM • QM + Qd: basic data for water resource assessment, modelling, indicators of EMF, permits for abstraction…

  8. RAINFALL • No historic data in Kosovo • Monitoring network needs to be rehabilitated • Available sources: • interannual averages from printed Hydrological Year Books • Master plan

  9. WATER BALANCE & STATISTIC QA

  10. SPATIAL DISTRIBUTION OF QA • Spatial distribution of rainfall • Q = (P – E) .S • Catalogue of QA/ database • Obtain immediately QA at any point of the basin

  11. FLOW DURATION CURVES (FDC)

  12. EMF INDICATORS • Q95%, Q90% or 1/10 Qmean

  13. NEXT STEPS / HYDROOGY • Complete the data collecting and verification (recent data especially) • Estimate peak flows & hydrographs • Water resource management modelling • Flood risk assessment: flood modelling and flood risk management

  14. WATER RESOURCE MANAGEMENT MODELLING • Objective • To better assess water availability • To improve the management of conflicting situations • To optimise water allocation

  15. Advice • Optimisation of the management, • Implementation of the securing policy OPERATING PRINCIPLE Input module • Uses / Needs • Drinking water supply • Irrigation • resources • rivers • aquifer • Infrastructures • dams • wat. capture Hydro DB Database Adjustment over a logged series Calculation module Formalisation and Modelling of the management rules Simulation Daily or monthly time step Over a given period With given management policies And given needs Output module Results In the form of graphs and tables Annual, monthly, daily By nodes: requests satisfied, shortages, flows... • Diagnostic • Need/resource

  16. FLOOD RISK ASSESSMENT

  17. THANK YOU FOR COOPERATION
