Water-deposited materials in Alaska are important for engineering uses because of their general flat topographic situation and abundance. For the purposes of this study, the airphoto patterns of water deposited materials are divided on the basis of origin as follows: coastal plain; stream-deposited materials in the form of flood plains and terraces; and deltas. There are several other water-deposited types such as lacustrine, valley fill, and the several outwash groups. Outwash materials are discussed in the chapter on glacial patterns since complete knowledge of the pattern and its suggested features frequently depend on an analysis of glacial events. Successful interpretation of conditions of various water-deposited materials is contingent on the treatment of each topographic situation as an entire and separate unit.
