Summary
A technician who measures the water depth, water level, and flow velocity of waterways such as rivers and irrigation channels, providing data necessary for water engineering design and maintenance management.
Description
Hydrographic surveyors use echo sounders, GNSS, total stations, etc., in waterway environments such as rivers, ports, and irrigation canals to measure water depth, water level, flow velocity, etc. The acquired data is processed and analyzed using CAD and GIS software to create cross-sectional diagrams and bathymetric charts. These are utilized in water engineering design, maintenance management, and disaster prevention measures. They handle everything from field survey planning and equipment operation to office-based data processing and report preparation, requiring high accuracy and flexible adaptability.
