摘要

Coastal environments such as marsh, dunes and estuaries are characterized by their high natural values what usually cause them to be considered as Site of Special Scientific Interest and subjected to high protection levels that make the activities sought to develop inside. The Bay of Santander is a very important environmental element, located in the north of Spain (Cantabria). Human spills to convert sea into land started about 1850 and gradually change the tide prism. This produced the Bay to start filling up and consequently, problems for the safety navigation. Whence the navigational channel must be periodically measured and dredged. Estuarine sediment accumulations are a product of continental and marine processes; the current work compiles and develops the process to estimate the grain size (sand, silt, clay, silty loam, sandy clay loam,...), Pb and Zn contents, and ripples from hyperspectral data.
