OBJECTIVE
At the end of the semester, the student shall be able to understand the coastal processes, coastal dynamics, impacts of structures like docks, harbours and quays leading to simple management perspectives along the coastal zone.
UNIT I COASTAL ZONE
Coastal zone - Coastal zone regulations - Beach profile - Surf zone - Off shore - Coastal
waters - Estuaries - Wet lands and Lagoons - Living resources - Non living resources.
UNIT II WAVE DYNAMICS
Wave classification - Airy's Linear Wave theory - Deep water waves - Shallow water waves -
Wave pressure - Wave energy - Wave Decay - Reflection, Refraction and Diffraction of waves
- Breaking of waves - Wave force on structures - Vertical - Sloping and stepped barriers - Force on piles.
UNIT III WAVE FORECASTING AND TIDES
Need for forecasting - SMB and PNJ methods of wave forecasting - Classification of tides -
Darwin's equilibrium theory of tides - Effects on structures - seiches, Surges and Tsunamis.
UNIT IV COASTAL PROCESSES
Erosion and depositional shore features - Methods of protection - Littoral currents - Coastal
aquifers - Sea water intrusion - Impact of sewage disposal in seas.
UNIT V HARBOURS
Structures near coast - Selection of site - Types and selection of break waters - Need and mode of dredging - Selection of dredgers - Effect of Mangalore forest.
