Hydrogeology of SMART Area in Lebanon: Water Resources Briefing

This briefing provides an overview of the hydrogeology in the SMART area of Lebanon, including information on precipitation, surface water, springs, and groundwater. Details on major rivers, springs, and aquifers are covered, highlighting the physical and hydrological properties. The study area's water resources, including volumes and sources, are examined in depth.

  1. SMART-Lebanon Briefing on Hydrogeology National Center for Remote Sensing Amin Shaban

  2. Location of the study area

  3. Water Resources 1. Precipitation *It ranges between 600-1000mm *According to Thiessen and Isohyts methods, the average PPt.=830mm. This is equivalent to a volume of 285 Mm3/years *25-35% of this volume is derived from snowmelt 2. Surface water * Only one permanent river is located : Abou Ali River, and there are a treble number of intermittent streams * Springs (on-land): Thee are around 75 issuing springs, with average discharge of about 20l/sec. This is equivalent to 50 Mm3/year * Springs (submarine): a common phenomenon along the Lebanese coastal line. There are ten of this type (littoral & off-shore), with total volume of 300 Mm3/year

  4. Physical and hydrological properties of a major rivers in/nearby the SMART area

  5. Volume of precipitated and evapotranspirated water from watersheds in SMART area

  6. Major issuing springs in SMART area

  7. Major submarine springs in the SMART area

  8. Water Resources 3. Groundwater * The area of study is almost covered by impervious rocks and thick alluvial deposits. However, the recharge into subsurface strata is relatively low. So far, the located aquifers are fed from the neighboring areas along the tilted bedding planes * These aquifers are mostly characterized the secondary porosity, which is attributed to fracturing and karstification.

  9. Hydrostratigraphic characteristics of major aquifers in the SMART area
