Hydrography survey
Hydrographic Section of Survey Department in Dubai Municipality responsible for all Hydrographic and Oceanographic activities in Dubai maritime zones include Dubai creek, territorial water ,EEZ area and international boundary to cover following the IHO international standards.
Hydrographic information is required for the safe, efficient and sustainable conduct of every human activity that takes place in, on or under the sea. Hydrography involves measuring the depth of the water and fixing the position of all the navigational hazards that lie on the seafloor, such as wrecks and rocks. This is done mainly with specialized ships and boats operating echo sounders and sonars, but also using survey aircraft fitted with lasers. Useful information can also be derived sometimes from satellite observations. Hydrography also involves measuring the tide and the currents.
Bathymetry Survey
The conduct of Bathymetric survey for Dubai territorial sea and creeks are done according to International Hydrographic Organization (IHO) Standards Special Order ,full seafloor search with maximum detection capability for Multi Beam Echo sounder System for High resolution seabed mapping and inspection system. And Order1A from the upper areas
Geophysical Survey
The geophysics survey is required on shore and offshore to identify the dedicated features which found through bathometric survey , here we use side scan system to get imager and geometrical height, marine magnetometer to observe metal features and sub bottom profiler to find The buried features
Hydrographic Survey equipment’s
Hydrographic surveying is the scientific measurement & we at Survey Department of Dubai Municipality are using very advance & Latest Hydrographic Survey equipment’s in order to achieve the precise & accurate data to meet the IHO specifications.
a. Single Beam Echo Sounder
b. Multi-Beam Echo Sounder with Side Scan Sonar
c. Global Positioning System
d. Sub-Bottom Profiler
e. Magnetometer
Oceanographic Observations
We conducting Oceanographic observation of physical phenomena of water this include Tide , Tidal stream, sound velocity profiler ,current, water temperature and sea bed Grab sample
Tide Station
DM has 6 Tide-Met stations along Dubai coast and Dubai Creek to measure water level and meteorological parameters. And also DM has deployed two offshore buoys to measure offshore meteorological and oceanographic parameters. System further integrates 6 existing tidal meteorological stations and 2 offshore buoys. In addition to the meteorological parameters, the buoy also measure water quality like water temperature, and conductivity.
The Main Objective of Hydrographic survey
1. Management of advanced maritime infrastructure
2. Becoming a global reference for the provision of marine infrastructure data for the Emirate of Dubai.
3. Precise bathymetric survey of full sea floor coverage according international standers
4. produce nautical charts for safe and efficient navigation of ships.
5. Support strategic planning of development of Dubai maritime zones.
