COASTAL CURRENTS MONITORING USING RADAR SATELLITES BASED ON WAVE TRACKING APPROACH

Abstract. Use of high resolution radar imagery for coastal currents monitoring has been known as an active topic in several research institutions. In this study, we demonstrate a new method for coastal currents monitoring based on current tracking by deformed wave reconstruction.

The magnitude and shape of the echoes (or waveforms) hold information regarding the surface characteristics that can be described analytically. Accordingly from this shape, several parameters can be construed, by comparing the real waveform with the theoretical curve. Safety in coastal zones containing coastal engineering for construction of ports, marine structures, beach erosion, natural hazards, and environmental problems are the issues related to hydrodynamic studies of currents, waves, and winds. Therefore, monitoring of coastal currents is very important .The ability of the internet to accompany our results to track past and near real-time movements of every coastal waters for monitoring is appropriate. Surface Current Mapping is utilized using an interface to radar altimetry data derived surface currents. Then Data access is available in a number of formats and protocols such as Google Earth KML and so on. In this study Jason1 satellite data has been used as input data for assessing the coastal environment.
