CE3024 Hydrographic Surveying Syllabus:

CE3024 Hydrographic Surveying Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES

 To provide the necessary knowledge and practical instrument operational and data processing skills needed for them to confidently accomplish a bathymetric survey in the real world
 To develop students’ critical and creative thinking, as well as cooperative attitudes & behaviour of working with others.

UNIT I INTRODUCTION, TIDES AND DATUMS

Overview of hydrographic surveying concepts- bathymetric and nautical charts- Basic tidal theorytidal observations and predictions – common types of recording tide gauges – different vertical datums – Indian tides.

UNIT II SOUNDINGS

Overview of depth data types- Working principle of echo sounders – characteristics and nature of underwater acoustic signals – transducers – error sources and calibrations- Advanced instrumentation.

UNIT III NAVIGATION AND POSITION FIXING

Horizontal positioning methods and requirements – concept of line and surface of position – positioning and navigation using satellite positioning systems – differential GPS and Real-time kinematic (RTK)

UNIT IV PLANNING AND DATA PROCESSING

General considerations for planning of an inshore hydrographic survey – ground and track control – practical soundings in inshore and coastal surveys – data processing and chart compilation – hydrographic software packages for data collection – processing and plotting.

UNIT V MARINE ENVIRONMENTAL MEASUREMENTS

Methods of measuring and recording of currents – composition of the sea bed – and solids in suspension – Case Studies (The role of the hydrographic surveyor on different marine projects)

TOTAL: 45 PERIODS
COURSE OUTCOMES:

On completion of the course, the student is expected to be able to
CO1 Learn the fundamentals of hydrographic surveying
CO2 Identify the appropriate techniques for different types of survey
CO3 Understand the various options available during the Navigation
CO4 Analyze the data collected from a survey and assess its quality against the project requirements
CO5 Discuss the different roles for a hydrographic surveyor on marine projects
