**Bathymetric & Hydrographic Surveys** map the topography, water depths, and sub-aquatic features of water bodies. Beena Enterprises utilizes survey boats, digital echo sounders, and satellite receivers to map underwater terrain with extreme accuracy.
Designing underwater pipelines, measuring reservoir siltation, or building bridge piers requires detailed bathymetric profiling. We deploy high-frequency single-beam or multi-beam echo sounders mounted on specialized boats, synchronized with RTK DGPS coordinates. This lets us generate 3D bathymetric contour maps and cross-sections representing riverbed erosion, silt deposition, and clearance paths.
Provides high-fidelity 3D maps of underwater terrain.
Allows precise volume calculation of silt deposits and dredging profiles.
Crucial for design and alignment of underwater pipes, cables, and piers.
Water storage reservoirs, dams, and irrigation headwork basins.
Rivers, lakes, ports, and navigation canals dredging assessments.
Underwater pipeline crossing and electrical cable laying routes.
Establishing control benchmarks on the river bank using static GNSS.
Calibrating transducer velocity based on local water salinity and depth.
Navigating the boat in parallel grids while continuously recording depths and coordinates.
Filtering water level changes, generating 3D underwater profiles, and contour maps.
