Abstract |
Lake Burullus is one of Egypt's four northern wetlands located along the Mediterranean Sea coast. Its water quality has deteriorated significantly due to huge agricultural drainage volumes, municipal, and industrial effluents. The main aim of this study is to map the Lake's surface water quality conditions utilizing remote sensing and Geographic Information Systems (GIS) as a tool for water quality monitoring using spectral water indices retrieved from Landsat satellite images. Nitrate, phosphate, turbidity, nitrogen, ammonia, iron, and total phosphorus were all represented on the output maps. Water samples from the lake were collected in October 2020 to demonstrate the lake's deterioration and changes in the measurements of analyses at this time of the year. Furthermore, a series of depth measurements were obtained at appropriate distances from each sample to create a map of the depths (Bathymetry map) inside the lake. Depth measurements followed drilling, disinfection, and dredging activities within the lake when samples were collected. The resulting maps demonstrated a suitable distribution of many water quality metrics. The most worse water quality was found in the eastern and southern extensions of the lake compared with other regions, owing to polluting drainage water and wastewater discharge in these areas. In summary, the study empahsises that remote sensing integrated with GIS are powerful tools to map water quality |
