Single Beam Echo Sounder (SBES) survey is a reliable and cost-effective hydrographic technique that emits a single sound pulse directly beneath the vessel to measure water depth. It is ideal for shallow waters, inland waterways, and as a complementary tool alongside multibeam surveys for cross-checking and verification. ________________________________________ Technology Overview • Single Pulse Emission – Measures depth directly beneath the vessel • Simple & Reliable – Proven technology with consistent results • Cost-Effective – Lower operational costs compared to multibeam • Shallow Water Capability – Ideal for rivers, lakes, and coastal waters • Quick Deployment – Rapid mobilization and survey execution • Easy Integration – Works with RTK GNSS for accurate positioning ________________________________________ Key Applications • Inland Waterways & River Surveys • Lake & Reservoir Depth Mapping • Shallow Coastal Water Surveys • Dredging Volume Calculations • Pipeline & Cable Route Verification • Navigation Channel Surveys • Pre-Construction & As-Built Surveys • Cross-Checking Multibeam Data ________________________________________ Deliverables • Bathymetric depth charts • Cross-section profiles • Volume calculations • Contour maps • GIS-ready data • Comprehensive survey reports
