Journal ArticleDOI
TL;DR: In this paper, a series of experiments were conducted in a wave flume, 72.5m long, 2m wide and 2.5 m deep, where a custom made strain gauge based force transducer has been mounted to measure two force components namely vertical and horizontal.

Journal ArticleDOI
TL;DR: In this paper, the authors used the Kamphuis (2002) formula for the estimation of longshore sediment transport (LST) along the entire coastal stretch of Kerala is challenging as the sediment transport pattern varies both spatially and temporally depending on the nearshore wave climate.

Journal ArticleDOI
TL;DR: In this article, the effects of high Re in predictive relationships for maximum amplitude response (Ymax) were investigated in a cylindrical structure with a towing tank, and a new equation was proposed to capture hysteresis as part of the main objective of the study.

TL;DR: In this article, the authors measured the sediment transport rates through measurements of the hydrodynamic driving parameters along the coast of major port of Chennai instruments were deployed for the measurement of waves and flow field.
Abstract: The east coast of the Indian Peninsula experiences the effects of a devastating cyclone at least annually. The Thane cyclone of 29–30 December 2011 has been once such event that resulted in significant damages along the coastline of Tamil Nadu on the southeast coast of India (13° 9′ 10′ N and 80° 21′E). Waves as high as 8–12 m in a water depth of 20 m have been measured. Such huge waves, combined with a storm surge of 0.5 m, lead to severe damages to coastal structures during the passage of the cyclone. As a part of an exercise in assessing the sediment transport rates through measurements of the hydrodynamic driving parameters along the coast of major port of Chennai instruments were deployed for the measurement of waves and flow field. The measurement campaign was carried out at a location of about 120 km north of the cyclone made landfall. The ENCEP wind data formed the input for executing the WAM model for the simulation of wave characteristics, which are compared with the measured wave data. The agre...
