| Popis: | Coastal erosion and accretion are short-term and long-term processes that may cause changes in shoreline and beach profiles. Monitoring beach profile is important to figure out the factors that are responsible for these changes so it helps the stakeholders in planning sustainable beach management that plays a vital role in achieving Integrated Coastal Zone Management (ICZM). For this reason, a beach survey was conducted at the study area to monitor and determine the factors that led to erosion and accretion on beach profile. DEM (Digital Elevation Model) helped on comparing between the elevations of ground control points through four seasons of the survey, which compensated: November 2020, December 2020, February 2021, April 2021 and July 2021. The used methodology of using GPS (Global Positioning System) depended on stop and go methodology within the two locations in the study area: site A (Jal El Bahr north of Tyre) and site B (Bahr Slaiyeb south of Tyre). GIS (Geographic Information System) is another tool that was used to have LC (land cover) map. Meteorological data was extracted from Saksakye weather station north of Tyre. Results of beach survey indicated that the two study areas were exposed to change on profile through the study period especially at Bahr Slaiyeb. These changes in the two study areas are a result of anthropogenic pressure (grooming and cleaning, grazing, human trampling, construction, etc..), vegetation cover and meteorological factors (wind speed, wind direction and precipitation). This database could be used to support in outlining the baseline of strategic beach monitoring and ICZM. |
