River bathymetry under the Old Iron Bridge, Delhi

Our hydrographic team works from a survey boat with a GNSS receiver and an echo sounder. The echo sounder records depth, the GNSS records position, and together they give bed levels across the whole channel. Life jackets on, every session.

What the client receives: bed contours, cross-sections, depth maps and XYZ data on the same datum as the land survey.
