Abstract
The Suez Canal runs through an important water body, the Bitter Lakes which are deepened regularly to suit passing by or parking vessels of different drafts. The bottom topographic is dynamically changing due to sedimentation by ships and water current movements that are usually impacting and requiring those continuing dredging processes performed by the Suez Canal Authority. Basically, studying the bottom dwellers of any lake requires bathymetric data which is very costly. Therefore, bathymetry maps can be derived from passive optical satellite sensors (multispectral). The present study used Landsat-8 and Sentinel-2 satellite imagery to produce water depth of the Bitter Lakes, Suez Canal. The satellite images data preprocessed then using log ratio to extract the raster values which integrated with in situ measured depth data to estimate absolute water depths. The landsat-8 resulted depth was supportive to detect bottom topographic, using two different datasets, one by using coastal band with R squared of 0.89 and the other dataset by using blue band with R squared of 0.84. Comparing with the Sentinel-2 resulted depth revealed R squared of 0.81 by using dataset of blue band and pixel size 10 m. The study could be used for further monitoring of lake bathymetry and detecting sedimentation dynamic.
