Abstract
Coastal processes are natural processes that operate along coastal zones, resulting in morphological changes in erosion and deposition. The western coast of India is affected by extreme monsoonal wave activity, which can lead to the loss of beaches and the vulnerability of the dunes. As a result, understanding actual near-shore physics and long-shore sediment transport becomes a prerequisite for the development of an effective coastal zone management strategy. The aim of this study is to quantify and investigate longshore sediment flux as a result of wave action based on sediment trap experiments (Kraus 1987). The Kraus (1987) method, along with wave hydrodynamics and current measurements, is performed using acoustic instruments across the surf zone.
Highlights
Coastal processes are natural processes that operate along coastal zones, resulting in morphological changes in erosion and deposition
Several instruments were deployed in a single crossshore transect to measure tides, currents, waves, and long-shore sediment transport characteristics
The sensors were installed in the order of the Recording Current Meter (RCM), Miniature Wave Buoy and Acoustic Doppler Current Profiler (ADCP) at a depth of 5 m, 7.5 m and 10 m, respectively
Summary
Coastal processes are natural processes that operate along coastal zones, resulting in morphological changes in erosion and deposition. The western coast of India is affected by extreme monsoonal wave activity, which can lead to the loss of beaches and vulnerability of the dunes. As a result , understanding actual near-shore physics and long-shore sediment transport becomes a prerequisite for the development of an effective coastal zone management strategy. The aim of this study is to quantify and investigate longshore sediment flux or rate as a result of wave action based on sediment trap experiments (Kraus 1987). The Kraus (1987) method, along with wave hydrodynamics and current measurements, is performed using acoustic instruments across the surf zone
