What types of hydrographic survey services does ROKIB HYDRO-TECH offer?

We offer comprehensive hydrographic survey services including Multibeam (MBES) and Singlebeam (SBES) bathymetric mapping, dredging volume estimation using the Trapezoidal method, river bank protection and scour monitoring, GNSS RTK positioning, geospatial data processing, and IHO S-44 compliance reporting for marine construction and navigation projects.

How do you ensure the accuracy of your hydrographic survey data?

We ensure data accuracy through rigorous MBES Patch Test calibration, GNSS RTK centimeter-level positioning, sound velocity profiling, and Total Propagated Uncertainty (TPU) analysis. All our surveys comply with IHO S-44 Special Order and Order 1a standards.

What is the Trapezoidal method for dredging volume estimation?

The Trapezoidal method computes dredging volume by calculating the average cross-sectional area between consecutive survey lines and multiplying by the distance between them. This provides precise pre-dredge and post-dredge material quantification for accurate cost estimation and contract management.

Can you handle large-scale river training and bank protection projects?

Yes, we have extensive experience in designing and implementing river bank protection works using riprap, geobags, and other erosion control measures. Our projects on the Jamuna, Padma, and Meghna rivers have successfully protected critical infrastructure, reduced erosion, and supported sustainable river management.

Who We Are & What We Deliver

ROKIB HYDRO-TECH is a specialized hydrographic surveying and river engineering consultancy with over 25 years of field experience on the Jamuna, Padma, and Meghna rivers — Bangladesh's most dynamic and challenging waterways. Our portfolio reflects our commitment to precision, innovation, and client satisfaction.

We provide end-to-end solutions for:

Multibeam (MBES) & Singlebeam (SBES) Surveys – High-resolution bathymetric mapping for navigation safety, dredging planning, and infrastructure development.
Dredging Volume Estimation – Pre- and post-dredging volume computation using the Trapezoidal method, ensuring accurate cost estimation and contract management.
River Bank Protection & Scour Monitoring – Design and implementation of riprap and geobag installations for erosion control and infrastructure protection.
GNSS RTK Positioning – Centimeter-level accuracy for precise georeferencing of all survey data.
Geospatial Data Processing – Advanced data processing, GIS mapping, and IHO S‑44 compliance reporting.

 Trusted by Port Authorities, Contractors & Government Agencies: Our survey data and engineering solutions have been used for dredging contracts, bridge foundation design, navigation safety assessments, and river training projects across Bangladesh.
