Nadine Nassif1 2Remote Sensing Center, National Council for Scientific Research, Beirut, Lebanon ABSTRACT The littoral of Lebanon has been impacted by several pollutants whose source is the terrestrial environment and human activities. The two major pollutants are detritus and organic materials. The detritus spreads over a large areal extent and consists mainly of sediments and debris from watercourses. Organic pollutants are mainly wastewater and oily and chemical residues. The factors influencing the spread of these materials into the sea were studied, including the physiography, landcover/use, and hydrography of the terrain. Remotely sensed data was used for the study. Major pollution sources appear as distinct optical features.and 34 are identified along the littoral, Field verification confirmed the satellite imagery information. Detritus and wastewater appear to directly flow into the sea and are often derived from sources at remote distances inland. Oil and chemical products appear to have a more diffusive flow behavior. Dynamic changes are much exaggerated in the case of wastewater and oil and chemical products. Reference: Nassif, N., and A. Shaban. 2007.
