Survey plan was prepared as guuidance during bathymetry survey. Collecting data was done by tracking the river/sea according to the planed routes. The routes are made every 10-15 meters depending on the width of the river/survey. Data correction is necessary to justify the result such as water level observation, to record tide detail and a tranducer offset measurement.
There are 2 Bathymetry Surveys :
- Sea; conducted in the beach area to ensure the safety of activity in the sea area. This survey resulting bathymetry map that cover the seabed over the particular area. This is useful for jetty/port location design to avoid any obstruction such as rocks, coral, calculate the tide to reach the safety distance for the port and shipping process.
- River; conducted along the the river area. It will cover riverbed as precaution while travelling in the river to avoid rocks, logs calculate the stream power to ensure safety distance for the shipment collections.
