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 Jason! satellite data has been used as input data for assessing the coastal environment. 1. INTRODUCTION ltimetry is basically a technique for measuring height. Satellite radar altimetry measures the time taken by a radar pulse to travel from the satellite antenna to the surface and back to the satellite receiver. Moreover, this measurement yields a wealth of other information that can be used for a wide range of applications tm, Many current studies are attempting to enhance the quality of altimetry data close to the coasts. New processing methods and applications can then be developed for littoral and shallow- water regions, some of the most fragile and important areas of the oceans. There is a shortage of altimetry data near the coasts (or their inferior quality) which is caused due to several factors: The technique itself, since the radar echoes reflected off water, and off a combination of water and land are not identical, and basically only the former undergo processing by the ground segments. Other altimetry satellite measurements also suffer from the same problem, such as those from the radiometer (at a distance of about 50 km from the coast) *. But even this amount of data needs to be used in a way which is effective and efficient. Since the satellite altimetry and radar observatory came to existence, various approaches have been offered to use their data in solving environmental problems and at most to construe and derive out valuable and profiting information to use in various areas of research. An alternative method for calculating surface currents is through the exploitation of the Doppler shift in synthetic aperture radar data (Chapron, 2005) P! This method has ! Corresponding author promise in particular for coastal zones, although there are many technical challenges, including isolating the surface currents from signals such as wave orbital motion or tides. Another method is a feature tracking algorithm to monitor ocean currents by using satellite sequential images of surface water (V.M.Krasnopolsky and et all, 1999) A One area of research is in waveform re-tracking reprocessing individual satellite track signals to recover the distorted waveform as it reaches land (Deng and Featherstone, 2006) DI One of the new ways of monitoring the coastal areas with radar technology is using the HF radar monitoring system. HF radar tracks currents and eddies of coastal surface waters from just beyond the surf zone to 150 km offshore. The movement of these surface waters can be viewed in near real-time in a Google Maps interface or at web pages developed for specific users. If an oil spill occurs, these maps and products can be used to track where the oil is moving, even at night or in dense fog and extreme weather. Similar maps and websites allow city environmental managers to follow the trajectory of coastal discharges(like sewage spills or coastal runoff after heavy rains)so that only the affected beaches are targeted for water safety testing and subsequent closures when needed to protect our health. In this paper unlike using pressure based or radar received wave power analyse which are examples of physical properties of water wave, the geometrical aspect of surface water wave is under concentration. So this can be described as a numerical and mathematical approach which applies on the oceanic water surface model taken from the altimetry data over a specific area [6]
