Modeling of paleohydrologic change during deglaciation.

Abstract

Modeling paleodischarges of former braided stream systems on each terrace surface is shown to be at a tentative stage, because of numerous error sources and assumptions that remain to be tested. These are discussed in relation to field measurements of channel width, depth, gradient and sedimentology; to theoretical modeling of flow depth, resistance coefficients, velocity, Froude number and discharge; and to geomorphic interpretation of the flow events being modeled.-from AuthorDept. of Geography, Univ of Aberdeen, St. Marys High Street, Old Aberdeen AB9 2UF, UK.
