About Engr. Md. Rokib Hossain

I am a Professional Hydrographic Surveyor and River Training Specialist with 25+ years of field experience across Bangladesh, Singapore, UAE, Canada, and the UK. My expertise spans the entire lifecycle of hydrographic projects — from designing river training structures (spurs, groynes, bank revetments) to executing high‑precision MBES bathymetric surveys and dredging volume calculations.

I have personally supervised river training works on the Jamuna, Padma, and Meghna rivers for over two decades, providing practical, cost‑effective solutions that withstand monsoon extremes. My work has been instrumental in protecting critical infrastructure, maintaining navigational channels, and supporting sustainable river management.

Core Engineering & Surveying Services

Hydrographic Surveying: Multibeam (MBES) and Singlebeam (SBES) operations, patch test calibration, sound velocity profiling (SVP), tide correction, and IHO S‑44 compliant data acquisition for ports, rivers, and offshore projects.
Dredging & Volume Computation: Pre‑dredge and post‑dredge volume calculations using trapezoidal and prismoidal methods, cost estimation, and production monitoring for TSHD/CSD dredgers.
River Training & Bank Protection: Design and supervision of spurs, groynes, geobags, riprap revetments, and slope protection structures for major rivers (Jamuna, Padma, Meghna).
GNSS & Geospatial Solutions: RTK/PPK surveying, geodetic projections, Total Propagated Uncertainty (TPU) analysis, and GIS mapping for engineering and environmental applications.
Equipment Repair & Calibration: Troubleshooting and repair of MBES, echo sounders, GNSS receivers, and total stations to minimize costly field downtime.
Engineering Tool Development: Custom engineering calculators and automation scripts for field data processing, reporting, and project management.

Why This Blog?

This blog is created to share real, field‑tested knowledge with fellow engineers, surveyors, and students.
