Multiscale Hydrologic Remote Sensing: Perspectives and Applications
3.1 INTRODUCTION
The dynamics of coastal zones with intensive sea–land interactions are complex, and
their interaction mechanisms are under continuous investigation. The coastal processes and their variability are driven by the interaction of waves, currents, winds,
and tides and their enormous forces that are applied on the bathymetry, causing massive changes in the coastal geomorphology by accreting or eroding the shoreline.
The sensing, monitoring, and modeling of such physical processes of coastal environments are crucial for the sustainable development of coastal regions and effective
management of the available land and water resources.
The acquisition of the appropriate data is essential but challenging, as the spatial
extent of the coastal phenomena varies from centimeters to kilometers, and the time
scale of the processes varies from milliseconds to decades. An example of the interaction of the phenomena is illustrated in Figure 3.1 for Sylt, a barrier island in North
Sea. The general practice has proven that a coastal monitoring system works well
