摘要：Coastal morphodynamics of any site is dependent on many factors such as environmental conditions,
sediment properties, human interference and their complex interaction. The human interferences due to infrastructure
development may lead to several problems such as Coastal accretion and erosion, choking of tidal inlets, formation of
sand bar, changes in the flow regime etc. To avoid excessive or unwanted morphodynamics changes at a desired
location, proper understanding of area before any infrastructure development to be taken up is very essential. Honnavar
location in Karnataka was selected to study the coastal dynamics and sediment transport based on the data available at
Central Water & Power Research Station (CWPRS), Pune. To study coastal dynamic features MIKE 21 HD
(Hydrodynamic Module) and for sediment transport MIKE 21 MT (Mud Transport Module) was used. Calibration of
model was done with field data to improve the accuracy of dynamic properties and to assess the sediment transport
pattern. The studies were carried for both monsoon and non monsoon season. The model was calibrated for non
monsoon season. Sedimentation studies indicated that during non-monsoon season deposition was taking place in the
river mouth due to low discharge from the rivers and formation of sand bars was noticed. During monsoon rivers carry
more suspended sediments and those sediments will be discharged into the sea. Due to high discharge from the rivers in
monsoon period the deposition was not taking place near the river mouth and it was distributing along the coast.
Further, it is planned to provide a hypothetical harbour layout and test it for the changes in the flow conditions and
sedimentation pattern so as to ascertain the trend of sedimentation in this region.
