In this paper, the authors investigated the dynamic stability of the NeendakaraKayamkulam sector on the coast of Kerala related to the offshore waves and local wind conditions and found that a major portion of the beach is dynamically stable except for a few hot spot locations.Abstract:
Beach processes along the NeendakaraKayamkulam sector on the coast of Kerala related to the offshore waves and local wind conditions are investigated. This study is based on the field observations made during March 2012 to March 2013, which indicates that a major portion of the beach is dynamically stable except for a few hot spot locations,wherein, the natural balance or equilibrium has been disturbed due to excessive mining or introduction of hard structures as a part of harbour development activities or shore protection measures. It is also observed that the condition of some of the areas which were under heavy erosion during the last decade has improved considerably or remained more or less stable in recent past probably due to the protection measures adopted.read more

Heuristic Models of Sand Transport in the Surf Zone
TL;DR: In this article, physical mechanisms for both the onshore/offshore and longshore modes of sand transport within the surf zone are described, and two important parameters are the wave steepness and ratio of fall velocity to wave period.
Beach profile change: morphology, transport rate, and numerical simulation
TL;DR: In this paper, an empirically based engineering numerical model is presented for simulating beach profile change in the surf zone produced by waveinduced cross-shore sand transport, which simulates the dynamics of macroscale profile change, such as the growth and movement of berms and breakpoint bars.

Numerical Model Studies on the Effect of Breakwaters on Coastal Processes — A Case Study along a Stretch of the Kerala Coast, India
TL;DR: In this paper, the authors report the application of numerical models as an effective tool to study the coastal dynamics of the area and also to quantify and assess the shoreline changes for predicting the seafloor evolution pattern over a period of time.
