Sounding Pole or Rod: Crafted from timber using a direct shoe, this rod is graduated to measure drinking water depth straight.
Surveyors spend unique attention to buying specific places of shallow parts, obstructions, and aids to navigation that alert mariners. In addition they document tide or drinking water stage measurements to deliver a vertical reference (imply decrease small h2o) for water depths.
Geo Procedure Corporation is on the mission. We’re not simply doing hydrographic surveys; we’re ensuring Bangladesh’s waters are Secure, stuffed with potential, and nicely looked just after.
Surveying this route is vital to ensure the fundamental bathymetry is Safe and sound for vessel passage.
