7 HF COASTAL RADAR The technology of HF Radar is based on the property of emitted Electromagnetic wave from a transmitting source being backscattered by sea waves Operating frequency: 25 MHz Spatial resolution : 750 x 750 m Range : > 20 km Magnitude error : < 5 cm/s Direction error : < 5 degrees Hourly radial maps are obtained averaging over a 1.10-hour interval with reference to a central hour The network of HF Radar is composed of three stations: Lido, Pellestrina and offshore Oceanographic Platform Radial data from two or more sites are combined to produce maps of vector currents within a regular grid.

17 Wireless networks for coastal monitoring The wireless networking technology can be used for improved coastal monitoring systems Main benefits Real-time data collection and dissemination In-network network processing of data Possibility of automatic intervention Quick reaction to sensed environmental changes Abundance of working technologies Low cost Easy to deploy Mobility can be fully supported Some challenges Application requirements drive network design Deployment and maintenance in rough environment Choice of proper technology Interdisciplinary dialogue is needed Sensor interfaces Must match node interfaces Power sources and energy harvesting
18 Low costs system for videomonitoring Applications: Shoreline and morphological time and space evolution Hydrodynamics Turistic fluxes Ship traffic..many others.. The camera control software permits a remote operator to schedule image collection of specified types of images at arbitrary desired intervals. The associated PC based controller performs camera control and image collection, creates the timeaveraged images (thereby sharply reducing data transmission overhead) and transmits the resulting to the remote data collection center.
