Explain tidal characteristics in terms of tide raising forces and local and regional morphological features Use tide tables and appropriate software to determine predicted water levels and tidal currents Explain the principles of operation of different types of water level gauges. Install, level and calibrate a water level gauge Configure water level gauges for logging data, data communication, data down load and for network operation with appropriate quality control measures Use tidal information, and vessel parameters to reduce soundings to a specified datum Configure and calibrate GNSS to reduce soundings to a specified survey datum Explain the forces behind currents and change in currents with tides Describe techniques for current measurement and identify appropriate methods for acquiring and displaying current data
Major harmonic constituents and different types of tide. Amphidromic points and cotidal charts Tide and current tables Tide prediction toolsChanges in water level caused by: atmospheric pressure, wind, seiches , oceantemperature and precipitationWater level variations inestuaries, wetlands and rivers
