  1. Optimization for Sustainable Water Resources Lebanon Case StudyThe Lower Litani River Basin First Management Board Meeting ELARD in cooperation with NCRS IzmirApril 1 and 2, 2005 Environmental and Water ResourcesManagement Consultants Lebanese National Center forRemote Sensing

  2. OUTLINE • Status of Stakeholders Involvement • Issues Questionnaire • Data Collection Progress • Model Tools and Scenarios

  3. Status of Stakeholders Involvement • Major Stakeholders were identified (<Stakeholders-general list-Lebanon>)Not fully taken into account in D01 • Still need to identify key communities to be involved and other major water users (farmers COOPs) • Key stakeholders are already involved in the project (Litani River Authority (GOV), NGOs, MoE) • Next steps: • Introducing remaining stakeholders to project (letters, issues questionnaires, interviews) • Local participatory workshop (?)

  4. Issues Questionnaires • Already tested by: • ELARD and NCRS • LRA (GOV) • Amwaj of Environment (NGO) • Comprehensiveness • Data availability (?) (under Water management) • R&D (under water management) • DSS (?) (under Water management)

  5. Issues Questionnaires (2) • Clarity: • Water scarcity • Coastal interaction • Coexistance of public and private responsibility, privatization • Gender issues • Technology and investments • Development of demand (generic) • Household/Tourism/Agriculture/Industrial Water Quality under Water Demand • Shipping and flooding (under Water demand, other uses)

  6. Issues Questionnaires (3) • Structure: • Water scarcity under physical conditions (?) or under Water Supply (as water availability)? • Separate groundwater availability and quality • Separate Standards and Quotas • Water Quality Issue within Demand and SupplyWhy not as a stand-alone category (in order to address key issues affecting water quality)?

  7. Issues Questionnaires (4)Comparative Analysis

  8. Data Collection and Availability • Identification:Lower Litani River Basin, South Lebanon • Description: • Coastal southern Lebanon along Eastern Mediterranean • Sub-Basin Area: 600 km2 • Elevations from 0 to 600 m amsl • Average annual precipitation: 700 mm • Over 100 springs and increasing number of groundwater wells • Around 120 towns and a total population of about 300,000 persons

  9. Data Collection and Availability (2) • Location: • GIS data and satellite imagery are available

  10. Data Collection and Availability (3) • Basin: • High-resolutionDEM is available

  11. Data Collection and Availability (4) • Land-use:

  12. Data Collection and Availability (5) • Meteorology: • Data available from the Lebanese Meteorological Service • Annual total/average precipitation and temperature; min/max/average, monthly total/average time series of daily values are available • Number of relevant stations being checked with LMS (limited number of stations – 1 or 2) • Hydrology: • Data available from the Litani River Authority

  13. Data Collection and Availability (6) • Monitoring infrastructure: • Major limitation with respect to water quality monitoring • No systematic monitoring of groundwater levels • No monitoring/measurement of water consumption (metering systems) • No systematic monitoring available other than hydrological and meteorological data • Water budget: • Precipitation = 282 million m3/year • Evapo-transpiration = 143 million m3/year • Runoff = 43 million m3/year • River discharge = 130 million m3/year • Different uses = 66 million m3/year • Groundwater storage = 100 million m3/year

  14. Data Collection and Availability (7) • Structures: • One major reservoir: Markaba • No water/wastewater treatment plants available • Water resources: • More than 70% of water consumption goes to irrigation • No environmental water use • Main source of water supply is from surface water • No unconventional sources • Domestic distribution networks need upgrading • Irrigation networks are still deficient and need to be implemented • No treatment facilities

  15. Data Collection and Availability (8) • Demography:

  16. Modeling • Basic review and initiation to manuals • Effective start after long expected modeling training workshop
