MEASUREMENT OF LONGSHORE SEDIMENT TRANSPORT IN THE COASTAL REGIONS USING WIRELESS SENSOR NETWORKPearlin Sam Jinoj T., Mahija Hann J. and Ramesh R.Abstract In this paper, we introduced a system using wireless sensor network suitable to measure long shore sediment transport in the coastal region over time periods. This wireless sensor system measures and quantifies the littoral sediment movement based on the empirical formula and the ocean physical parameters such as significant wave height, current speed, current direction, etc. This oceanographic sensor system includes microcontroller, hardwares and sensors interconnected with long and short range wireless modem. The microcontroller triggers the sensor with suitable sampling interval, process the data and send the data through GSM/GPRS to the receiving base station. The real time data processing, prediction and validation were done by collecting the multi data series of different location sensor nodes. The WSN system is experimented and tested in the lagoon of Kavaratti Island during February 2018. The purpose of this research is to acquire real time datasets with low cost to investigate periodic coastal morphology dynamic changes and sediment transport processes particularly during extreme events. |
