Using single-beam bathymetric data technique to estimate dredging: a case study in Lake Manzala (Egypt)

Abstract Marine dredging is an excavation activity carried out worldwide. Dredging a critical component of most major infrastructure developments the lakes. This research work was conducted, using two epoch data (year 2016 and year 2022), to investigate changes in morphometry Lake Manzala. Data acquisition done depth sounding with echo sounder GPS, further processing ArcGIS 10.7.1 software. Results obtained for activities Manzala were as follows: slight change its surface area, aquatic macrophytes removed, inside fish farms have been completely appearance mud islands, high amount removed sediment. The total area estimated at 524.94 million m 3 from With continuous process, results manuscript serve good reference material decision policy formulation relating.
