TECHNICAL CAPABILITY FOCUS

Bathymetric & Hydrographic Surveying

Echolocation profile mapping for waterbeds, rivers, and ponds. Essential for channel dredging computations, bridge pier designs, and coastal revetment audits.

Precision Rating: Depth Resolution: ±1cm, IHO Special Order CompliantVerified SOB Standard

Technical Overview & Standard Operating Procedure

Bangladesh's dynamic river systems require constant underwater bathymetric depth profiling to maintain navigable shipping channels and prevent vessel groundings. Our hydrographic team measures underwater topography and sediment accumulation.

Execution Methodology & Equipment Calibration

Survey vessels equipped with South SDE-28S single-beam echo sounders tied to RTK GPS receivers record bathymetric depths. Data points are corrected for real-time water tide variations.

Key Application Scenarios

Capital dredging quantity calculation
Bridge foundation & riverbed scour monitoring
Port & jetty bathymetric depth charting
Reservoir capacity and siltation mapping
