Emirates Nortech Surveys provides an excellent quality bathymetric/Hydrographic Surveying Service. These Hydrographic Surveys are performed in/along Coastal Areas, rivers, areas near to jetties etc. A Differential Global Positioning System is used as local base station system for the navigation and positioning purposes during the survey. Trimble Hydro data logging & processing software’s are used for the measurement and storage of the position and depth survey data. A bar-check is carried out prior to the commencement of the bathymetric/hydrographic survey.

The Bathymetric Survey is carried out by running longitudinal run-lines at right angles to the shore line. Several lines running parallel to the coast line are also surveyed for the primary purpose of confirming the Bathymetric Data Quality and Integrity. Predicted tides are referred for reduction of soundings. In normal cases Nortech would run a water level monitoring station established within the site area and a survey team would record water level at regular 5 minute intervals.

A Bathymetry Chart/Drawing is prepared to show the interpolated depth sounding values. Contours are drawn at 0.5m or any other suitable interval. A Final Survey Report is submitted to the client including a Bathymetric Chart/Drawing of the surveyed area at a suitable scale.
